monograph on the fundus ocuH of vertebrates 

 figures the retinal surface of the eye of many 

 mammals, including a white man, a negro and a 

 chimpanzee. The deeply pigmented iris of the 

 chimpanzee shows the most striking resemblance 

 to that of the negro, while its basic similarity to 

 that of the white man is masked by the loss of 

 pigment in the latter. Only man and the apes 

 have a macroscopic "macula lutea" or spot of 

 clearest vision on the retina (Plate, 1924, p. 690). 

 The lacrymal bone, in the inner corner of the 

 eye, affords additional evidence of the close 

 relationship of man and the anthropoids. Not 

 only are its general form and connections strikingly 

 similar in man and chimpanzee (save for the very 

 small size of the "hamular process" in the apes) 

 but Le Double notes' that in Deniker's gorilla 

 foetus the lacrymal bone begins to ossify in the 

 same place that it does in the human foetus to- 

 ward the end of the fourth month, namely, in the 

 covering membrane of the ethmoidal cartilage 

 and on the inner side of the lacrymal sac; that, 

 like the human foetal lacrymal, it consists of an
