On Human Milk By C. Meymott Tidy, M.B. London Hospital, Whitechapel, London, England. Milk has always been regarded as a model food. For upon this diet, prepared by nature without the hand of the adulterator, elaborated expressly for one object, the child, and, in short, all the young of the mammalia, live, grow, and thrive. And these principles, and in their due proportion, must constitute not merely the food of the young child, but the food of the full-grown man too, when he has long ceased to be The infant, Muling and puking in the nurse's arms.
Human milk is described as a white, fatty, and rather thick fluid.
But with respect to its colour, I have noticed it of a deep yellow, and occasionally, though much less frequently, of a decided blue tinge. And these varieties of colour are not so much dependent as some seem to have imagined upon peculiarities of diet as upon disordered states of the system. After being allowed to stand for some time woman's milk, like that of the cow, separates into two layers. Upon examining human milk under the microscope, we see that it consists of numerous, highly refracting, transparent oil and fat globules floating in a clear liquid. On the addition of a little dilute acetic acid, we shall discover a thin membrane investing these globules.
