I. Histologica! studies of calf skin In the case of tanning of leather and manufaeturing of gelatin, the skin always must be soaked in lime solution. Then the tissues and organs in the skin will make a lot of morphologically remarkable changes. Accordingly, in th first place the writer has observed minutely the tissues and organs of the backskin of the Holstein calf. The principal results obtained are as follows : 1. There was no great difference between the skin of the Holstein species and that of others. The former was composed of epidermis, corium and subcutaneous tissue that existed in animals skin in general. 2. The lucidum layer on that epidermis of the back skin, the appearance of which had not been reported, was discovered in this reserch. 3. The papillate layer of calf skin, occupying 45^ of all skin thickness, was comparatively thicker than that of the matured cattle skin, -while the reticular layer of calf skin was relatively thin. It was recognized distinctly that the sweat gland and the hair of calf skin were inferior in development to those of the matured cattle skin. 4. There was a little difference between the type of. collagen fibre in the papillate layer ani that in the reticular layer. The rcil form of the so-called grain layer was morphologically not yet clearly recognized. In the
