Pipette

“ The pipette varies in capacity from 1 to 200 cubic centimètres.
Dr Fresenius gives the following directions for its use:—“To fill a pipette with the fluid which it is intended to transfer from one vessel to another, the lower part of the instrument is dipped into the fluid, and suction applied to the upper aperture, either direct with the lips or through a caoutchouc tube until the fluid in the pipette stands a little above the required mark ”

“ To hold your tongue is bad enough, but to hold your breath as well, in competition with a small, silent boy with a solemn face, serious eyes, and lungs apparently of gutta-percha, who seems to suffer no inconvenience from feats of endurance that would exhaust a Red Indian, is more than a mere daughter of Eve can compass.
They were in the Consulting Room at the time, Father having gone out, as he always did between eleven and one; and the various unexplained mysteries of that delightful apartment, which were becoming a serious strain upon Pipette's feminine curiosity, once more lay before them. ”

“ This was repeated at regular intervals of temperature down to 4° C. (= 40° F) , when the water was again heated, the pipette thoroughly cleansed by introducing benzine into the pipette in a manner similar to that by which the oil was introduced. The surplus water which accumulated in the funnel was allowed to escape through the syphon by relaxing the lever of the pinching device. It is obvious [Pg 87] that the number of seconds, in each case, corresponds to the viscosity. ”

“ Don't you see that it gives us an infallible test for blood stains. Come over here now!" He seized me by the coat sleeve in his eagerness, and drew me over to the table at which he had been working. "Let us have some fresh blood," he said, digging a long bodkin into his finger, and drawing off the resulting drop of blood in a chemical pipette. "Now, I add this small quantity of blood to a litre of water. You perceive that the resulting mixture has the appearance of pure water. The proportion of blood cannot be more than one in a million. ”

“ Near the Talking-Hole, on a small table, stood "The Terriphone." This, they gathered, was a sort of long-distance talking-hole. You turned a little handle, and, taking a queer, cup-shaped arrangement off a hook, conversed affably through it with unseen people, situated somewhere at the back of beyond. The children had seen Mr. Evans use it for sending messages to Father via Mr. Pipes. Mr. Pipes was a great friend of Pipette's. In the first place, he wore a uniform, which always appeals to the feminine mind. ”

“ To use a pipette, the absorbing liquid is brought to the outlet of the capillary by tilting or by squeezing a rubber ball fixed to the wide end, and the liquid is maintained there by closing with a clip. The capillary is connected with the measuring tube by a fine tube previously filled with water. The clip is removed, the stopcock opened, and the level tube of the measuring apparatus raised, so that the gas passes into the first bulb. There it is allowed to remain, the pipette being shaken from time to time. ”

“ To escape temptation, he had to lose himself in prayer kneeling at the far end of the laboratory. Unfortunately, the still warm liqueur was still releasing a hint of aromatic fumes, which swirled around him, and led him on regardless towards the vats.... The liqueur was of such a lovely golden green colour.... Poised above it, his nostrils aquiver, he stirred it very gently with his pipette, and in the twinkling eddies, which were spreading throughout the emerald ambrosia, he thought he saw the sparkling, laughing eyes of aunty Bégon looking back at him....
—Oh! Alright! ”

“ In all biological work involving the counting of organisms, either by the plate or direct method, in the case of yeast, the operator works as rapidly as possible to prevent the organisms from settling, so as to have them evenly distributed in order that he may obtain an average sample. A pipette is used for removal of a drop of the liquid and the drop placed in the chamber as quickly as possible to prevent settling. ”

“ Pipes.—In reference to these essentials to smoking tobacco, a great variety of tastes are displayed, while that of each country forms an amusing contrast to that of its neighbour. In the Eastern portion of the globe, the gorgeous hookah or superb chibouque with their serpent train are caressed: in France, the short twisted pipe: in Germany, the merschaum: in Holland, the long slender black pipe: in America, the short red clay pipe, or the ingeniously manufactured, yet murderous tomahawk, bears the tube of comfort; while in England—happy England—all, or any of these, are attainable. ”

“ The accompanying figures represent the Irish bagpipes in their primitive and improved forms. We have here the earliest pipes, originally the same as the Scotch, as appears from a drawing made in the sixteenth century, and given in Mr. Bunting's work; but they now differ, in having the mouthpiece supplied by the bellows A, which, being filled by the motion of the piper's arm, to which it is fastened, fills the bag B; whence, by the pressure of the other arm, the wind is is conveyed into the chanter C, which is played on with the fingers, much like a common pipe. ”

“ Having filled his pipe, he put the surplus tobacco back again, as if his pocket were a drawer. Then, he took a live coal from the fire with the tongs, and lighted his pipe at it, and then turned round on the hearthrug with his back to the fire, and went through his favourite action of holding out both his hands for mine.
"And this," said he, dandling my hands up and down in his, as he puffed at his pipe; "and this is the gentleman what I made! The real genuine One! It does me good fur to look at you, Pip. All I stip'late, is, to stand by and look at you, dear boy!" ”

“ Many a soldier sadly misses his pipe, which of course may not be lit on a night march; but to me a greater loss is the silence of those other pipes, for the sound of the bagpipes will stir up a thousand memories in a Highland regiment, and nothing helps a column of weary foot soldiers so well as pipe music, backed by the beat of a drum. ”

“ The first kind of European pipes were walnut shells, a hole being bored in one side for the reception of the stem—a common straw. It is possible that we get from this early form of tobacco pipe the term "straw," as applied to modern long clays, if, indeed, they are not named like straw-berries, from the material which protects them from injury.
CARVED WOOD PIPE, 61⁄2 INCHES HIGH. TOBACCO PLACED BEHIND HORSE'S HEAD.
The custom of using a pipe common to an assembled company was, no doubt, partly due to the circumstance that tobacco was at one time a most costly thing. ”

“ And their doctrine is this:—The term "pipe" doth comprise every part which any given pipe possesses, whether it be differentia, property, or accident. And a pipe which, whether by reason of its mouthpiece, lid, colour, or joint in its bowl, stem, or mouthpiece, hath in it more than one kind of matter, cannot be simple. For they define the term simple as denoting an absolute unity of matter, and allege that as amber both true and false, ivory both true and false, bone and every manner of composition (as to mouthpiece) , gold, silver, and base metal (with regard to lids) ”

“ But they always carry their little stools slung on their backs, and no one ever moves without his loved pipe. Upon their pipe they lavish all their artistic powers, which, however, are not very considerable. Precious as is iron in this country, being used, like gold in Europe, as a medium of currency, the pipes are all mounted with this costly metal. The bowls are made of clay, conical in shape, and having a couple of prongs on which to rest. They are very large, holding quite a handful of tobacco, and their mouthpieces are almost invariably made of iron. ”

“ Our gossip about the Indian weed may now be brought to a close with a few words about its co-partner, the pipe. For even tobacco-pipes, like all other products of men’s ingenuity, awaken interest all the more engrossing when little else remains to tell the story of those who made them and used them. They carry the imagination back to those shadowy palaces of the Incas and Aztecs, where equally shadowy potentates smoked out of pipes made of precious metals, or of highly polished and richly-gilt wood. ”

“ Pip ate enough salt beef and damper to half kill him, drank more tea than he had ever disposed of at one sitting in all his fourteen years, swung himself into his saddle in close imitation of the oldest stockman, and thought if he only could have a black, evil-looking pipe like Tettawonga and the rest of the men his happiness would be complete and his manhood attained. ”

“ For the work-a-day and knock-about pipe the wooden pipe with short stem is without a rival. The qualities which are essential for a wooden pipe are many and it is difficult if not impossible to get any material that will answer all of them. The wood for such a pipe must be hard and practically incombustible, yet light. It must be sapless and inodorous so that when heated the fragrance of the tobacco would not be mingled with that of the wood and be lost. ”

“ Piping, pī′ping, adj. uttering a weak, shrill, piping sound, like the sick: sickly: feeble: boiling.—n. act of piping: sound of pipes: a system of pipes for any purpose: small cord used as trimming for dresses, &c.: a slip or cutting taken from a plant with a jointed stem.
Pipistrel, Pipistrelle, pip-is-trel′, n. a small reddish-brown bat. [Fr.]
Pipit, pip′it, n. a genus of birds resembling larks in plumage and wagtails in habits, the most common British species being the titlark.
Pipkin, pip′kin, n. a small earthen pot. [Pipe.] ”

“ The tobacco pipes in use in that part of Australia are curious. One form consists of a hollow tube as thick as a man’s arm, stopped at the ends and having one hole near the bottom into which is introduced the stem of a pipe, and another hole near the top through which the smoke is imbibed. Their use of the pipe is rather singular. When a party desires to smoke, the chief man lights the pipe, places his mouth to the orifice, and continually inhales until the interior of the hollow stem is filled with smoke. ”

“ Like fire-flies! Will-o'-the-wisps!
And make believe we're hiding, all the way,
Till we come out into a sunny land,—
All vines and sunlight, yes, and men that sing!
Far, far away—forever.
[Gives ILSE a bowl to feed the other children]
[JAN pipes a measure of the Kinder-spell, brokenly. The PIPER turns.
So! Thou'lt be
My master, some day. Thou shalt pipe for me.
JAN [piping] Oh, wasn't that one beautiful?—Now you! ”

“ The pipes resemble modern ones in shape, and often bear manufacturers' marks, which make it practicable to estimate their age. The oldest of them are supposed to have been made during the reign of Queen Elizabeth. Probably the oldest illustration of a tobacco-pipe in Great Britain is in a carving on a chimney in the keep of Cawdor Castle, where among the devices are a mermaid playing the harp, a monkey blowing a horn, a cat playing a fiddle, and a fox smoking a tobacco-pipe. ”

“ In this tobacco and my pipe,
I'll count it all the fairer.
Then give me but Virginia's weed,
An earthen bowl, a stem of reed,
What care I for the weather?
Though winter freeze, or summer broil
We rest us from the days of toil,
My Pipe and I together.
HERMANN RAVE.
THE OLD CLAY PIPE.
There's a lot of solid comfort
In an old clay pipe, I find,
If you're kind of out of humor
Or in trouble in your mind.
When you're feeling awful lonesome
And don't know just what to do,
There's a heap of satisfaction
If you smoke a pipe or two. ”

“ The pipes are of three kinds: (1) a simple valved insufflation tube or “blow-pipe,” by means of which the performer fills the bag reservoir; (2) the “chaunter” (chanter) or the melody-pipe, having according to the variety of the bag-pipe a conical or a cylindrical bore, lateral holes, and in some cases keys and a bell; the “chaunter” is invariably made to speak by means of a double-reed; (3) the “drones,” jointed pipes with cylindrical bore, generally terminating in a bell, but having no lateral holes and being capable, therefore, of producing but one fixed note. ”

“ It is the broken belly of the beast, and thy bellows there are his lungs, and these pipes are his throat, those feathers are of his tail, and thy rattles the gnashing of his teeth." Pipes must have been pretty popular with the low as with the high, when a Bartholomew Fair toyman, as a matter of course, kept them in stock. ”

“ Teit by the Indians for the making of the flange or other thickening at the mouth of the pipe stem was to prevent the string used in attaching the pipe to the wooden stem slipping off. According to all of them, wooden stems were always used with tubular pipes as with elbow and simple bowl pipes; for a person cannot smoke any kind of stone pipe more than a few draws before it becomes too hot for the lips. To Mr. Teit's mind, no matter how small the bore of the pipe, a regular stem must have been used for smoking. ”

“ A pipe, then, is a thing instrumental to our participation in the energy developed by tobacco in the state of positive existence. Now all will acknowledge that of pipes some are good, some bad, and some indifferent; let it be ours to inquire in what a pipe's excellence or goodness consists, and what kind of pipe is most likely to possess this excellence. Now a pipe that is excellent in all respects is a rare and precious thing, not to be acquired every day, and deserving of much attention when possessed. ”

“ The smoke-pipe at the top of the barrel is cut from an old stove-pipe and is shaped as shown in Fig. 1. With a tin-shears or snips the ears are cut at top and bottom. Those at the top are pointed and give a crown effect, but if the plain-rim top is preferred do not cut the pipe. At the bottom, slits are cut in the pipe two inches in from the edge, about three-quarters of an inch apart, and with a flat-nosed pliers the ears are bent out so that they will lie flat on the barrel-top when the smoke-pipe is set in place. ”
