In the December number of ' The American Naturalist,' Dr. H. W. 

 Band has given an extended abstract of Friedenthal's experimental 

 proof of blood-relationship." The blood of the Gat and the Ocelot is 

 physiologically equivalent. The carotid arteries of these two animals 

 were connected so that an exchange of blood took place from one to 

 the other. No hemoglobin appeared in the bladder of either animal. 

 But if a Cat and a Babbit be connected in the same way, both animals 

 die in a few minutes from the poisonous effects of the foreign blood 

 upon the central nervous system. The effect of human serum was 

 tried upon the blood of six species of Apes — [Platyrhines) , Pithesciurus 

 sciureus and Ateles ater ; [Qatar rhines), Cynocephalus babuin, Macacus 

 sinicus, M. cynomolgus, and Rhesus nemestrinus — at the Berlin Zoological 

 Garden. In all cases the human serum dissolved the Ape corpuscles. 

 Among the true Anthropoid Apes is found blood which is physiologi- 

 cally equivalent to that of man, as was proved by experiments made 

 with an Orang-outang, a Gibbon, and a ten-year-old Chimpanzee, just 

 as the blood of such widely separated races as the negro and white is 

 physiologically equivalent. The writer concludes that such experi- 

 ments justify the placing of man and the Anthropoid Apes together in 

 the same family, " or at least in the same suborder, rather than 

 isolating man in a suborder of primates, coordinate with the suborders 

 of the Platyrhines and Catarrhines." 



At a meeting of the Zoological Society on Dec. 17th, 1901, a com- 

 munication was read from Mr. G. Metcalfe, M.A., of New South Wales, 

 concerning the reproduction of the Duckbill (Ornithorhynchus anatinus). 

 The author stated that he was of opinion, after many years' observa- 

 tion of the ariimal, that the Duckbill was viviparous, and that the 

 young were not, as was generally supposed, hatched from the eggs 

 after they had been deposited.
