x884*_i The Significance of Human Anomalies. 675 
brain. This uncovered condition of the cerebellum was well 
seen in an idiot’s brain that I lately had the privilege of 
examining ; the fissures were also of the confluent type ; 
the whole brain only weighed 16 ounces. The internal 
organs in man, although not subject to great variations, still 
are sometimes found abnormal. The liver may be divided 
into a number of lobes, as is seen in the gorilla. This is 
called a degraded liver. The spleen is often deeply notched 
and multiple, as in the case in some of the lower animals, 
and the uterus is occasionally double ; an arrangement which 
is the normal one in the mare, raccoon, rabbit, and other 
animals. It is double in the human fcetus up to the fourth 
month, and frequently a trace of this bifid condition is seen 
in adult life. 
I could multiply, ad infinitum , the variations in human 
anatomy which have their corresponding normal condition in 
the lower animals, but I think I have described a sufficient 
number of examples to show how common these animal 
resemblances are in man. On what theory can we account 
for their existence, except that they are reversions to some 
pre-existing and lower type ? This is the only logical con- 
clusion to which the study of morphology leads us, and “ to 
take any other view,” says Darwin, “ is to admit that our 
own structure and that of all the animals around us is a 
mere snare laid to entrap our judgment.”
