MAN . —His first form is that which is permanent m the animal rule . His organization gradually passes through conditions generally resembling a fish , a reptile , a bird , ancl the lower mammalia , before it attains its specific maturity . At one of the last stages of his foetal career , he exhibits an intermaxilliary bone , which is characteristic of the perfect ape ; this is suppressed , and he may then be said to take leave of the simial type , and become a true human creature . The brain of man ,
which exceeds that of all other animals in complexity of organization and fullness of development , is , at one early period , only " a simple fold of nervous matter , with difficulty distinguishable into three parts , while a little tail-like prolongation towards the higher parts , and which hacl been the first to appear , is the only representation of a spinal marrow . " Now in this state jt perfectly resembles the brain of an adult fish , thus assuming in transitu the form that in the fish is permanent . In a
short time , however , the structure is become more complex , the parts more distinct , ancl the spinal marrow better marked ; it is now the brain of a reptile . The change continues ; by a singular motion certain parts ( corpora qttadrigeminaj , which had hitherto appeared on the upper surface , now pass towards the lower ; the former is their permanent situation in fishes and reptiles , the latter in birds ancl mammalia . This is another advance in the scalebut more remains yet to be done . 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 . This organ , in the mammalia , consists of four cavities , hut in the reptiles of only three , and in fishes
of two only , while in the articulated animals it is merely a prolonged tube . Now in the mammal foetus , at a certain early stage , the organ has the form of a prolonged tube ; and a human being may be said to have then the heart of an insect . Subsequently it is shortened ancl widened , ancl becomes divided by a contraction into two parts , a ventricle and an auricle . It is now the heart of a fish .
