Vacuole

“ There is often a distinction, clear, but never sharp, between the richly vacuolate, almost frothy ectoplasm and the denser endoplasm. One or more contractile vacuoles may protrude from the ectoplasm. The endoplasm contains the nucleus or nuclei. The nucleus when single may be central or excentric: in the latter case, the endoplasm contains a clear central sphere (“centrosome”) on which abut the axial filaments of the pseudopods. ”

“ Cell-wall firm not gelatinous, rarely forming colonies. Fore-end of the body with two or four (seldom five) flagella. Almost always green in consequence of the presence of a very large single chromatophore. Generally a delicate shell-like envelope of membranous consistence. 1 to 2 simple contractile vacuoles at the base of the flagella. Usually one eye-speck. Division of the protoplasm within the envelope may produce four, eight or more new individuals. ”

“ In the matter of diet the person in health, if he exercises ordinary care, may be left to find out for himself what suits him. The soured milk remedy is not a disagreeable one, as, when properly prepared, the article forms 156 both a pleasant and refreshing article of diet. The question of getting the right article, however, is a very important one. Milk is a splendid rearing ground for many bacteria, some of which are very injurious; among these may be pathological germs, the seeds of tuberculosis, enteritis, etc. ”

“ The reaction of human milk is slightly alkaline; of cow's, neutral or slightly acid. The specific gravity of each is about 1.028 to 1.032. Human milk is sterile when secreted, but derives a few bacteria from the lacteal ducts. Cow's milk, as usually sold, contains large numbers of bacteria. Microscopically, human milk is a fairly homogeneous emulsion of fat, and is practically destitute of cellular elements. ”

“ Of milk, especially, much has been written and said as a disease-transmitting medium, and with every good reason, and, if the statement of a Continental authority may be accepted that each time we eat a slice of bread and butter we devour a number of bacteria equal to the population of Europe, we have sure grounds for seeking for further information as to what these bacteria are and what they are doing. ”

“ The digestive juices are apparently able to take care of a very great number of germs; it is after the food has passed on down, and is lodged in the large intestine, that the real fermentation and putrefaction begin—and these count for more, in the question of health, than that which goes on in the butcher-shop or the refrigerator or the pantry.
Do not misunderstand what I mean by this. I am not advocating that anyone should swallow the bacteria of deadly diseases, such as typhoid and cholera ”

“ In boiling eggs for invalids, let the white be just set; if boiled hard, they will be likely to disagree with the patient.
In Miss Nightingale’s admirable “Notes on Nursing,” a book that no mother or nurse should be without, she says,—“You cannot be too careful as to quality in sick-diet. A nurse should never put before a patient milk that is sour, meat or soup that is turned, an egg that is bad, or vegetables underdone.” ”

“ The moment the milk enters the human maw or stomach, the juice of the stomach converts it into curds—into solid food, just as readily as when it enters a calf’s maw or stomach, and much more readily than by rennet, as the fresh juice is stronger than the stale. An ignorant mother often complains that because, when her child is sick, the milk curdles, that it is a proof that it does not agree with him! ”

“ Attention must be paid to the cleanliness of the vessel, and care should be taken that the milk be that of ONE cow, and that it be new and of good quality; for if not, it will turn acid and sour, and disorder the stomach, and will thus cause either flatulence or looseness of the bowels, or perhaps convulsions. I consider it to be of immense importance to the infant, that the milk be had from ONE cow. ”

“ Disease among cattle, poultry, and fish has increased so alarmingly in the last few years that we should no longer depend on the animal kingdom for food. We should look to the grains, nuts, vegetables, and fruits for a better dietary than can be prepared [4] from the flesh of animals likely to be contaminated with tuberculosis, cancer, and other diseases.
In writing this book, the author has treated the subject from the commonly accepted definition of the term vegetarianism, which means to abstain from flesh food, but allows the use of eggs, milk, and its products. ”

“ Nature provides that the milk for young animals is supplied in finely divided streams, so that coagulation takes place in the best possible way.
The proteids are the most important constituents of food; they are abundant in the blood, 54 and build up the muscles, brain, nerves, and other bodily structures. ”

“ Diet.—The diet will depend upon the severity of the disease. If the fever is high and the cough persistent, the strength of the food of nursing infants should be reduced. We can reduce the strength of the food by giving the child a drink of cool boiled water before each feeding and shortening the length of each feeding. Older children may be given toast, milk with lime water, cocoa with milk, broths, gruels, custards, cereals and fruit juices. ”

“ Infants in nursing move the jaws to obtain the milk, and the working of the infant’s jaw mixes the milk with the saliva, and thus fits that milk to go into the stomach. After being subjected to the action of the stomach for two or three hours the food becomes fitted to pass into the circulation by absorption. To have good food, therefore, it is necessary that it be made of proper material properly prepared. We are furnished with milk to start with as we enter the world. Had meat been the best diet, we should have been born with beefsteaks in our hands. ”

“ Again, milk and the preparations from milk, are a most important article of food for the sick. Butter is the lightest kind of animal fat, and though it wants the sugar and some of the other elements which there are in milk, yet it is most valuable both in itself and in enabling the patient to eat more bread. ”

“ When this organ is coated, indicating gastric catarrh, small quantities of thin chicken soup, egg albumin, thin barley- or rice-water, are better borne than milk; when the tongue is or has become clean, then milk, pure, diluted with barley- or rice-water, or peptonized, is the best diet. ”

“ Between the villi are found the openings of the intestinal glands.
Internal Structure of a Villus.—The internal structure of a villus is best seen in a longitudinal section. We find the outer wall made up of a thin layer of cells, the epithelial layer. It is the duty of these cells to absorb the semifluid food from within the intestine. Underneath these cells lies a network of very tiny blood [Pg 309] vessels, while inside of these, occupying the core of the villus, are found spaces which, because of their white appearance after absorption of fats, have been called lacteals. ”

“ In the small intestine, there is a multitude of tiny projections (villi) from the folds of the mucous membrane, more than seven thousand to the square inch, giving it a soft, velvety look. These little rootlets, reaching out into the milky fluid, drink into their minute blood vessels the nutritious part of every sort of food. (2.) The lacteals [Footnote: From lac, milk, because of the milky look given to their contents by the chyle.] (p. 126) , a set of vessels starting in the villi side by side with the veins, absorb the principal part of the fat. ”

“ In cooking, parasitic animals which are strong enough to survive the ordeal by acid in the stomach are killed, and the food itself is made more accessible, the indigestible cellulose envelopes of the vegetable cells being burst open, and the collagen of the connective tissues converted into gelatin.
No less important than the quality of our food is the quantity; and here, again, we get a good illustration of the necessity for regarding the body as a whole. A healthy man’s appetite is his best guide, and if he follows it he cannot go far wrong. ”

“ All physicians, ancient and modern, allow that a milk and seed diet will totally cure before fifty, and infinitely alleviate after it, the consumption, the rheumatism, the scurvy, the gout—these highest, most mortal, most painful, and most obstinate distempers; and nothing is more certain in mathematics, than that which will cure the greater will certainly cure the lesser distempers. ”

“ Raw Vegetables that become Parts of Animals, are bruised, ground, and comminuted by the proper animal Organs, and mixed with animal Juices in their Passage. By this Means their Juices are expressed; such of them as are capable of mixing with Water naturally, or by the intermediate Assistance of the Bile, are formed into one common fluid Mass or Chyle, which constitutes the first Nourishment of Animals; whence the Blood, Serum, Lymph, and other animal Juices are formed. ”

“ Here are some pictures showing how people get the germs of consumption into them unless they are very careful.
A large number of cows have the germs or seeds of consumption in them, and they give out these germs in their milk. So milk ought to be "sterilised," that is to say, it should be made so hot that the germs are killed before it is drunk.
[Illustration: DO NOT DRINK MILK STRAIGHT FROM THE COW, AS A GREAT
NUMBER OF THESE ANIMALS HAVE THE GERMS OF CONSUMPTION IN THEM.]
Then a large number of people have the consumption germs in them, although they may not yet be ill with it. ”

“ Care must be taken of what I before advised, that before the Milk be thoroughly brought into Use, the latent Acid in the Bowels be first corrected and discharged by absorbent and cleansing Medicines, and a laudable Diet premised for some Time, that no Coagulation of the Milk, or other Inconveniencies, be incurred. Upon this Foot a certain Cure is to be expected. A prudent Physician will easily dispose a Body whose Powers are not entirely destroyed to receive this Diet. ”

“ In this stomach it is digested, and from the digested mass the chyle is formed, which, being absorbed by the lacteal vessels, is afterwards thrown into the mass of blood, and becomes the principle of nutrition to all the solids and fluids of the body. The intention of rumination, or chewing the cud, seems to be, that the food may be sufficiently comminuted, that, being more fully acted on by the stomachs, it may afford the greatest possible portion of nutritive juices. ”

“ The same measures may be resorted to where the milk, though satisfying in character, is deficient in quantity; and in preparing artificial food for the child it must always be remembered that the food requires to be adapted to the stage of development which is manifested by a young infant's digestive organs. ”

“ SYMPTOMS OF EMPTINESS OR STARVATION, WHICH MAY LEAD TO CHOLERA. If, as heretofore mentioned, the solid or nutritive principle of the milk has been withheld from the babe by adulteration in any way, the blood becomes watery, the fat cells cannot develop, the tissues that hold the fluid with which to moisten the parts dries away, and the flesh becomes soft or skinny. The milk may be nutritive, too, and yet for some reason fail to mix with the juices in the stomach so as to insure healthy blood. ”

“ If the patient’s vital powers are low, the milk may be peptonised by using Fairchild’s powders or by adding a little of Benger’s Liquor Pancreatices. In cases when milk cannot be taken in sufficient amount, animal food may be given in the form of plain meat broth. ”

“ Never attempt to carry the milk warm in a vacuum jug. If you do, the bacteria that are present in milk will multiply many times, with the result that when the milk is fed to the baby, it will make him sick. ”

“ The voluminous bowel or colon of man is a legacy from remote pre-human ancestors, whose food consisted of bulky, fibrous and slowly digested vegetable matters. It was more useful then, than now that most of our food is highly cooked. About a third part of the fæcal matter consists of bacteria of numerous species, though chiefly of the species known as the bacillus coli communis, one of the less harmful kind which is a constant inhabitant of the intestinal tract in man and animals. ”

“ When the infant is to be fed with cow milk, that from various cows is submitted to examination by the medical man, and, if possible, tried on some child, and when the milk of any cow has been chosen, no other milk is ever suffered to enter the child’s lips, for a French lady would as soon offer to her infant’s mouth the breasts of half-a-dozen wet-nurses in the day, as mix together the milk of various cows, which must differ even as the animals themselves, in its constituent qualities. ”

“ Experience proves that animal food most readily augments the solid parts of the blood, the fibrine, and therefore the strength of the muscular system; but disposes the body, at the same time, to inflammatory, putrid, and scorbutic diseases; and the character to violence and coarseness. On the contrary, vegetable food renders the blood lighter and more liquid, but forms weak fibres, disposes the system to the diseases which spring from feebleness, and tends to produce a gentle character. ”

“ Three or four glasses a day will be enough, and even that may be too much if the patient eats well of other things. In place of raw milk, it may be peptonized, malted, given hot, made into junket, taken in cocoa, or as one of the flavoured milkshakes, or turned into clabber or buttermilk. These varieties of milk are good for advanced patients, who may also be given egg albumen, flavoured with lemon, orange, ginger ale, grape juice, and so forth. The family must be taught to make these little innovations, in the ordinary diet, and instruction in these is part of the nurse’s work. ”
