The fate of these inorganiccompounds has not been certainly traced, but they give rise later on to the presence in the plant of various amino acid amides, such as leucin, glycin, asparagin, &c. That these are stages on the way to proteids has been inferred from the fact that when proteids are split up by various means, and especially by the digestive secretions, these nitrogen-containing acids are among the products which result.
But even when inside it does not follow that the Fungus can kill the cell, and many cases are known where the Fungus can break throtigh the cells first lines of defence (cell-wall and protoplasmic lining); but the struggle goes on at close quarters, and various degrees of hypertrophy, accumulation of plastic bodies or secretions, discolorations, &c.,, indicate the suffering of the still living cell.
This modification is important, because it transfers the formative influence from the plastic substances to the protoplasm, suggesting that, the diverse constituents are produced (whether spontaneously or as the result of stimulation) as secretions by the protoplasm.
- Many ants feed largely and some almost entirely on the saccharine secretions of other insects, the best known of which are the Aphides (plant-lice or " green-fly ").
While some of these " guest " insects produce secretions that furnish the ants with food, some seem to be useless inmates of the nest, obtaining food from the ants and giving nothing in return.
Each opens in a vas deferens which bears three diverticula or vesiculae seminales, and three pairs of cement glands also are found which pour their secretions through a duct into the vasa deferentia.
The caseous necrosis of the implicated mass of lung tissue, and indeed of tubercles generally, is held to be, in great measure, the result of the necrotic influence of the secretions from the bacillus.
Sometimes acid sometimes alkaline properties predominated in the juices and secretions of the body, and produced corresponding disturbances.
In the application of chemistry to the examination of secretions Willis made some important steps.
Formica), in stinging nettles, in some mineral waters, in animal secretions and in muscle.
Thick and said to be made up largely of the secretions of organisms. Such thicknesses of such material go far to modify the former opinion that the Tertiary periods were short.
The peculiar odour evolved by many rodents is due to the secretions of special glands, which may open into the prepuce, as in Mus, Microtus and Cricetus, or into the rectum, as in Arctomys and Thryonomys, or into the passage common to both, as in the beaver, or into pouches opening near the vent, as in hares, agoutis and jerboas.
The spherical granules (G) are probably gland-secretions; the dark bodies (Z) are probably xanthellae, i.e.
Besides the secretions already mentioned as being stimulated, the bile, the tears and the perspiration are increased by the exhibition of this drug.
It consisted of ethereal fire, and he was not subject to the ordinary phenomena of digestion, secretions and evacuations.
The respiratory rhythm is less frequent and the breathing less deep; the heart-beat is less frequent; the secretions are less copious; the pupil is narrow; in the brain there exists arterial anaemia with venous congestion, so that the blood-flow there is less than in the waking state.
There is much uncertainty as to the influence of atropine on the secretions of the stomach, intestines, liver, pancreas and kidneys, and it is not possible to make any definite statement, save that in all probability the activities of the nerves innervating the glandcells in these organs are reduced, though they are certainly not arrested, as in the other cases.
It is now known that similar internal secretions, or hormones, pass into the blood from every organ and tissue, so reaching and affecting every part of the body.
Physical symptoms also appear; the face assumes an earthy colour, the body wastes, constipation is usually present to an extreme degree, the secretions become arrested, loss of appetite and indigestion follow and the mouth is parched.
It is excreted by all the secretions and excretions of the body.
Xiv.), and (4) certain natural secretions (xv.).
Deals with the rites of purification rendered necessary by various natural secretions, and is therefore closely related to chap. xii.
Schizomycetes exist in every part of the alimentary canal of animals, except, perhaps, where acid secretions prevail; these are by no means necessarily harmful, though, by destroying the teeth for instance, certain forms may incidentally be the forerunners of damage which they do not directly cause.
In this sense alone quinine is a tonic. The hydrochloric acid of the gastric juice is stated to convert any salt of quinine into a chloride, and it seems probable that the absorption of quinine takes place mainly from the stomach, for when the drug reaches the alkaline secretions of the duodenum it is precipitated, and probably none of it is thereafter absorbed.
The similarity of the symptoms to those of cholera is very marked, but if the suspicion arises it can soon be cleared up by examining any of the secretions for arsenic. More rarely the poison seems to centre itself on the nerve centres, and gastro-intestinal symptoms may be almost or quite absent.
For the fact that, from the point of view of observation, reason and the will are merely secretions of the brain, and that man following the general law may have developed from lower animals at some unknown period of time, only explains from a fresh side the truth admitted thousands of years ago by all the religious and philosophic theories--that from the point of view of reason man is subject to the law of necessity; but it does not advance by a hair's breadth the solution of the question, which has another, opposite, side, based on the consciousness of freedom.
