Leak

“ One leak will sink a ship; and one sin will destroy a sinner. ”

“ The flues cannot stand such treatment, as they are thinner than the shell or flue sheet, and therefore cool much quicker, and in contracting are drawn from the flue sheet, and as a matter of course must leak. A flue, when once started to leak, seldom stops without being set up, and one leaky flue will start others, and what are you going to do about it? ”

“ A tempest ceases, a cyclone passes over, a wind dies down, a broken mast can be replaced, a leak can be stopped, a fire extinguished, but what will become of this enormous brute of bronze? ”

“ In two days there won’t be a single leak, and our boat will have no more water in her than there is in the stomach of a drunkard. ”

“ One leak will sink a ship, and one sin will destroy a sinner. ”

“ Act on the same principle you would if you had a barrel that had leaked its contents and you desired to refill it,—first stop the leak. It is absolutely necessary that you study cause as well as effect, if you would know yourself. ”

“ If one hole in a Dutch dyke is stopped up, more pressure is thrown on another weak point and a leak will soon appear there. There is but one Name that casts a spell over all the ills that flesh is heir to. ”

“ A small leak will sink a great ship, as Poor Richard says; ”

“ If there is an odor of gas anywhere in the house, especially in a dark closet, do not search for the leak with a match or a lighted candle. If you should happen to find the leak you might cause an explosion or set the house on fire.

“ If their occupation is actual work they prefer to pump water into cisterns, two of which leak through holes in the bottom and one of which is water-tight. A, of course, has the good one; ”

“ If a pail leaks, there must be a hole. Looking at the pail, we might imagine the water runs from many holes; but no matter how we might try to stop the imaginary holes from without, the water would not cease running. ”

“ If the usual flush applied immediately afterwards clears this off, the form of pan and the flushing power are satisfactory. By removing the wood-work around the w.c., leakage or spillings of slop-water around the w.c. can be detected. ”

“ There'll be some leakage in practice and we won't have time to build up that much negative potential every time we shoot, but if we only do half that well, we'll have a pretty thorough-going charge of lightning ... ”

“ To each of these premises he goes with the knowledge that a portion of the total leakage of 2000 gallons an hour is almost certainly there, and that it must be found, which is a very different thing from visiting three or four hundred houses, in not one of which he has any particular reason to expect to find leakage. Even when he enters a house with previous knowledge that there is leakage, its discovery may be difficult. It is often hidden, sometimes underground, and may only be brought to light by excavation. ”

“ If any breach is made in the pipe system, a leakage takes place, causing an alteration in the level of the mercury in the manometer, which may, if desired, be arranged to ring a bell. The manometer should in any case be observed regularly on the opening of the strong-room. ”

“ If the material be so porous as to permit a considerable leakage of air through it, there will naturally result a continuous change of air in the working chamber, and a corresponding relief of the men from the deleterious effects which are nearly always produced by over-used air. ”

“ In making malarial smears it is better to wash the finger or ear with soap and water to get rid of all grease and dirt. Then dry thoroughly before puncturing. Alcohol is not so efficient.
Fig. 150.—1, 2, 3, 4, Making blood smears on slide. 5. Smear ready for staining—grease marks prevent Wright stain from running over slide. 6. U-shaped glass tubing to hold slide in staining. 7. Right hand holding two cover-glasses. One cover-glass is being touched to drop of blood from ear. 8. Cover-glasses transferred to left hand in preparing to place one cover-glass on another and spread film. ”

“ The cover-glass on which the film has been spread, is floated before the latter has time to dry, film downwards on a saturated solution of corrosive sublimate in a watch glass for half an hour. The cover-glass is placed in distilled water and then in alcohol to remove excess of corrosive sublimate, and then stained. A little care is required when washing the film to prevent it sliding bodily off the cover-glass.
3. By drying and passing rapidly through the flame of a Bunsen burner, exactly as in preparing specimens of sputum, &c. (p. 111) . This method is handy for ordinary clinical purposes. ”

“ Or when did we ever see them dissolved into the four real elements? If a part is reduced to a kind of dust, it is not real dust, but ashes, which can be used for healing purposes. Another part which is reduced to a kind of water is not real water, but an expressed liquid, a juice either poisonous or nourishing, but not drinkable water. The portion which is dissolved into a kind of air is vapour or fume, but no air fit to be breathed. ”

“ At the end of either of the above periods of time, the cover glass is lifted out of the staining solution and, without washing, immersed in our five per cent. solution of nitric acid and alcohol. It is this part of the process, if any, which will give trouble, as the time of immersion is governed by the thickness and general character of the sputum. My custom is to hold the first cover immersed until the color has just disappeared, or say fifteen seconds, and the second five seconds longer; but a very little experience will remove any difficulty from over-decolorizing. ”

“ At all times and to all pictures water is more or less dangerous, unless used with the greatest caution, and then it should only be applied by means of a piece of thick buckskin leather well wrung out, and left just wet enough to slip lightly over the surface of the picture. ”

“ At the present stage of the inquiry there are, as I take it, three discoveries to make, starting from that smear. Find out (first) whether there is any article of dress in this house with the smear of the paint on it. Find out (second) who that dress belongs to. Find out (third) how the person can account for having been in this room, and smeared the paint, between midnight and three in the morning. If the person can't satisfy you, you haven't far to look for the hand that has got the Diamond. ”

“ Rest the cover-slip, film side uppermost, on the rubber mat.
2. By means of a drop-bottle, cover the film side of the cover-slip with the selected stain, allow it to act for a few minutes, then wash off the excess in running water.
The penetrating power of stains is increased by (a) physical means—e. g., heating the stain; (b) chemical means—e. g., by the addition of carbolic acid, 5 per cent. aqueous solution; caustic alkalies, 2 per cent. aqueous solutions; water saturated with aniline oil; borax, 0.5 per cent. aqueous solution. ”

“ The stain is more conveniently applied upon cover-glasses than upon slides. Films much more than a month old do not stain well. In some localities ordinary tap-water will answer both for diluting the stain and for washing the film; in others, distilled water must be used. Different lots of Wright's fluid vary, and a few preliminary stains should be made with each lot to learn its peculiarities. ”

“ These stones and metals, these bodies, so compact and solid, are disunited, are destroyed, by the agency of air, water, and fire; which the most ordinary analysis is sufficient to prove, as well as a multitude of experience, to which our eyes are the daily evidence. ”

“ No attempt should be made to brush or apply powder to prints in dust, obviously greasy prints, or bloody prints, as this will almost surely destroy them. Objects which have been wet or immersed in water may still bear identifiable latent impressions. ”

“ As the water evaporates, it leaves behind these non-volatile poisons, which are deposited as a thin film over the whole surface of the skin. As each day passes, the process continues, and the film thickens. If the skin is moderately active, three or four days suffice to form a layer which may be compared to a thin coating of varnish or sizing. ”

“ There are secret conduits or rivulets of the liquid matter, which communicates fire and heat into all parts more or less, and melts the stones and cinders by fits in those places where it toucheth them, over and over again; where it meets with rocks or houses of the same matter (as many are) , they melt and go away with the fire; where they find other compositions, they turn them to lime or ashes (as I am informed) . The composition of this fire, stones, and cinders, are sulphur, nitre, quicksilver, sal ammoniac, lead, iron, brass, and all other metals. ”

“ The ordinary way to make these scientific curiosities is to drop a small quantity, usually less than half an ounce, of perfectly fluid glass into water. In falling, the glass will assume the form of a tear, with an elongated end extending into a thread. ”

“ Bleaching.—The clean disintegrated rag is next bleached by means of ordinary bleaching powder solution. Bleaching powder is a substance prepared by the action of chlorine gas on dry slaked lime, resulting in the formation of a compound which has the property of bleaching or “whitening” vegetable matters. The clear solution obtained by treating the powder with water is utilised by the paper-maker for bleaching the rag pulp. ”

“ Each drop is composed of literally millions of minute specks of water that have condensed each about a minute mote of dust. These motes are a million of times below anything that may be seen with the most powerful microscope. ”

“ Clouds of dust were driven up into the skies, and the plain became covered with banners, lances, and all kinds of arms, and with emblems of every colour and device, torn and broken, and soiled with blood and dust. ”

“ The floating dust of the air, which, thus illuminated and observed, is as palpable to sense as any dust or powder placed on the palm of the hand. In the still air the dust gradually sinks to the floor, or sticks to the walls or ceiling, until, finally, by this self-cleansing process, the air is entirely freed from mechanically suspended matter. ”

“ If the paper thus prepared is exposed to light under a negative, or in another way if some places before exposure are protected by black ink or strips of paper, the places affected by light become dark coloured and brown, and at the same time they have lost their power of swelling up in cold water. ”

“ If the blood has fallen on such substances as wood or metal, the spot is black, has a bright glistening surface, and, if observed by a lens, exhibits radiating fissures and a sort of pattern, which, according to some, is peculiar to each species ”

“ Loss of strength may be due to impurities in paper, such as residues of the chemicals used in the preparation of the pulp, to the impurities in the pulp itself, or to the use of gas as the agent for lighting and heating. ”

“ If, now and again, my puppets or my plot-wires creak a bit noisily,—what then? Creaking, at worst, is a sure indication of movement,—of action,—of incessant progress of sorts. A thing that creaks is not standing still and gathering mildew. It moves. ”

“ Subsequently the ruins were turned over in search of treasure, and the tablets still further broken; and then, to complete their ruin, the rain, every spring soaking through the ground, saturates them with water containing chemicals, and these chemicals form crystals in every available crack. ”

“ Fixing and Staining.—A drop of the watery extract of the stain may be placed on a microscope slide and allowed to dry in the air, covered to protect it from dust, and then fixed by heating the slide over a spirit or Bunsen flame or by the use of absolute alcohol. When fixed, the preparation can be stained with eosin and methylene blue, methylene violet, or other nuclear dye. The film may also be fixed and stained with Leishman‘s solution in one procedure, or fixed by heat first and then stained with Leishman. ”

“ A regulation has adopted a test for the discovery of artificial coloring matter which in brief consists in rubbing tea leaves reduced to dust upon semi-glazed paper with a spatula and examining the smear with a lens. ”

“ Nay, a more advanced science will probably show that even his ashes, in their last analysis, are an invisible, gaseous substance. Nine tenths of a man’s body, we can even now prove, are water; and water, we all know, may be decomposed into invisible gases, and then made to reappear as a visible liquid. ”

“ All the dust which thus lies hidden in cloth, when it comes to the surface, acts as grit or powder insensibly but certainly, and helps to wear away the surface whenever it is touched. That we take in dust every time we go out will appear from inspecting a silk hat. Again, the dust on a coat, &c., every time it is rubbed by the cleanest hand, takes in grease, which in time aids in spoiling the surface. In fact, half the wear-out of all cloth is due to dust alone. ”

“ Structure revealed by microscopic examination must be compared with that of known substances; chemical and spectrographic analysis has to be checked by reference to a codified series of earlier tests; crackle on a surface can only be labelled as false if the nature of genuine crackle is known; 23 and the reading of whatever is discovered by X-ray, ultra-violet, or infra-red rays calls for comparison with verified results of previous examinations. The facts yielded by one method of investigation may by themselves not be sufficient evidence of forgery ”

“ The paper negative, without being fixed, is immersed in a bath of chemicals that dissolves away the sensitized surface that has been oxidized by the light from the camera lens—that is, the image—leaving on the paper only the unoxidized, or unexposed, parts of the sensitization. ”

“ Nay, in metals, which when melted are liquid but more tenacious, the melted drops often recoil and are suspended. There is something similar in the instance of the child’s looking-glass, which little boys will sometimes form of spittle between rushes, and where the same pellicle of water is observable ”
