In such a case, we see no reason why a wire muzzle, such as used by us after the operation for Entropium, might not be worn for an indefinite period, without any inconvenience to the animal. The caruncula lachrymalis is a small glandular body situated at the internal commissure of each eye.

For the same reason we must regard the salivary glands, which open into the mouth, as epidermic glands, as they are formed, not from the glandular layer of the gut like the rest of the alimentary glands, but from the epidermis, from the horny plate of the outer germinal layer.

The glandular activity of boys and girls is perhaps not so unlike as to justify society in giving them a different kind of education and preparation for group life. The excuse for two sorts of training is that the two sexes will not do the same work after puberty.

He will be able to classify the endocrine traits of the population exposed, and to advise a course of glandular feeding for the types specially liable. The Schick test for diphtheria susceptibility is an illustration of one method of approach to the problem of the epidemiologist in settling who needs protection.

Some of its effects are to furnish the blood with chemicals that act as fuel to the muscles, assisting them to contract more vigorously, to make the lungs more active in introducing oxygen into the system, to make the heart more active in distributing the blood throughout the body. Such glandular activity is an important physiological condition of these higher levels of energy.

The milk is abstracted from the blood in the glandular part; the tubes receive and deposit it in the reservoir, or receptacle; and the sphincter at the end of the teat retains it there until it is wanted for use. This must not be understood, however, as asserting that all the milk drawn from the udder at one milking is contained in the receptacle.

All our perceptions or ideas of external objects are universally allowed to have been originally excited by the stimulus of those external objects; and it will be shewn in a succeeding section, that it is probable that all our muscular motions, as well those that are become voluntary as those of the heart and glandular system, were originally in like manner excited by the stimulus of something external to the organ of motion.

This cortical or glandular substance constitutes the surface of the cerebrum, and also the surface of the corpora striata, from which proceeds the medulla oblongata; it also constitutes the middle of the cerebellum, and the middle of the spinal marrow.

Such an adrenal personality is entirely normal, within the definition of the normal as something not threatening the duration of life, nor comfortable adaptation to it. So are the other glandular types. No sharp line can be drawn between the normal and the abnormal in any case, the borderland is wide, the transitions many. The skin is one of the chief clues to the adrenal personality.

Such a proof, however, can by no means be produced so as to enforce conviction; for it would involve the impossible assumption, either that there is no essential difference between the degree of civilisation of the European nations, in the most ancient and in modern times, or that detrimental circumstances, which have yielded only to the civilisation of human society and the regular cultivation of countries, could not formerly keep up the glandular plague.
