Effect of Light on Bacteria

Abstract

The object of this communication is to prove, with the aid of accurate drawings, that there exists an essential resemblance between the constituent parts of the suprarenal bodies of mammals and certain structures in the mammalian ovary that are of occasional but normal occurrence. The appearances on which the comparison is based are best seen in the suprarenals of the dog and horse, and in the ovaries of the bitch. The suprarenals of the horse and dog are known to have, immediately under the fibrous tunic, a zone of follicles of singular though well-defined structure. The first point in the communication is one of criticism, and has reference to the division of parts within the suprarenal. It is held that the outer zone of follicles, as they are seen in the horse and dog, are quite unique among the structures composing the suprarenal, and are broadly contrasted with the rest of the organ lying internal to them. The contrast is unmistakable in these two animals.
