On the other hand, the optic thalami, which lie between the latter, belong to the second division, which develops from the "intermediate brain "; to the same section belong the single third cerebral ventricle and the structures that are known as the corpora geniculata, the infundibulum, and the pineal gland.
It is evident, therefore, that in rabbits, whatever influence the corpora lutea may have in the first half of pregnancy, they have none in the second half, and that at this period the essential hormone proceeds from the developing foetus or foetal placenta.
The complication of the organ increases; cavities termed ventricles are formed, which do not exist in fishes, reptiles, or birds; curiously organized parts, such as the corpora striata, are added; it is now the brain of the mammalia. Its last and final change alone seems wanting, that which shall render it the brain of MAN." And this change in time takes place. So also with the heart.
Balnea, vina, venus, corrumpunt corpora nostra, At faciunt vitam balnea, vina, venus! Wine, women, warmth, against our lives combine; But what is life without warmth, women, wine! I. Blood absorbs oxygene from the air, whence phosphoric acid changes its colour, gives out heat, and some phlogistic material, and acquires an ethereal spirit, which is dissipated in fibrous motion.

If this theory is sound, it would follow that corpora lutea are not formed in cases where the ova are not retained in the oviduct during their development. The essential process in the development of these structures is the hypertrophy and, in some cases at least, multiplication of the follicular cells in the ruptured follicle.
So that the correspondence in general structure, in the minute structure of the tissues, in chemical composition and in constitution, between man and the higher animals, especially the anthropomorphous apes, is extremely close. Shows a human embryo, from Ecker, and a dog embryo, from Bischoff. Labelled in each are: a. Fore-brain, cerebral hemispheres, etc. b. Mid-brain, corpora quadrigemina. c.
He hesitated to blow out his candle, uneasy at the darkness which seemed to him inhabited, full of ambushes and threats. He decided at last to extinguish it, and repeated the stanza he had already heard sung that evening in chapel: Procul recedant somnia Et noctium phantasmata, Hostemque nostrum comprime, Ne polluantur corpora.
The officer, who was an old soldier, seemed to be prepared for precautionary measures of this sort, and drew forth the corpora delicta skilfully from all the folds of my little trunk. I tried to bribe him with a tip, which he actually accepted, and I was all the more indignant when, in spite of this, he denounced me to the authorities.
Moreover, there is one circumstance in which the orang's and chimpanzee's brains resemble man's, but in which they differ from the lower apes, and that is the presence of two corpora candicantia the Cynomorpha having but one.
