422 ON GENERATION. 



mouth is enormous, and the tongue lies in its middle ; the eyes 

 are small, without lids to cover them ; the middle integument of 

 the regions of the forehead and sinciput is not yet cartilaginous, 

 far less bony; but the occiput is somewhat firm and in some 

 sort cartilaginous, indicating that the skull already begins to 

 acquire solidity. 



The organs of generation have now made their appearance, 

 but the testes are contained within the abdomen, in the situation 

 of the female uterus, the scrotum still remaining empty. The 

 female organs are yet imperfect, and the uterus with its tubes 

 resembles the two-horned uterus of the lamb. 



The placenta, of larger size, and now attached to the uterus, 

 comprises nearly one half of the entire conception, and pre- 

 sented itself to my eye as a fleshy or fungous excrescence of 

 the womb, so firmly was its gibbous portion connected all 

 around with the uterine walls, which had now grown to greater 

 thickness. The branches of the umbilical vessels struck into 

 the placenta like the roots of a tree into the ground, and by 

 their means was the conception now, for the first time, con- 

 nected with the uterus. 



The brain presented itself as a large and soft coagulum, full 

 of ample vessels. The ventricles of the heart were of equal 

 capacity, and their walls of the same thickness. In the thorax, 

 and covered by the ribs, three cavities, nearly of the same dimen- 

 sions, were perceived ; of these the lowest was occupied by the 

 lungs, which are full of blood, and of the same colour as the 

 liver and kidneys ; the middle cavity was filled by the heart and 

 pericardium; the superior cavity, again, was possessed by the 

 gland called the thymus, which is now of veiy ample size. 



In the stomach there was some chyle discovered, not very 

 different in character from the fluid in which the embryo swam. 

 It also contained some white curdled matter, not unlike the 

 mucous sordes which the nurse washes particularly from between 

 the folds of the skin of new-born infants. In the upper part 

 of the intestines there was a small quantity of excremeutitious or 

 chylous matter ; the lower bowels contained meconium. In the 

 urinary bladder there was urine, and in the gall bladder bile. 

 The intestinum coecum, that appendix of the colon, was empty 

 as in the adult, and apparently superfluous, not as in the lower 

 animals the hog, horse, hare, constituting as it were another
