78 THE THEORY OF EVOLUTION 



time enough be allowed, a relationship between the 

 bloods of all mammals is made evident. 



(2) The degrees of relationship between man, 

 apes and monkeys have already been noted. 



(3) Anti-carnivore sera show "a preponderance 

 of large reactions amongst the bloods of Carnivora, 

 as distinguished from other Mammalia; the maxi- 

 mum reactions usually take place amongst the more 

 closely related forms in the sense of descriptive 

 zoology." 



(4) Anti-pig serum gives maximum reactions only 

 with the bloods of other species of the same family, 

 moderate reactions with those of ruminants and 

 camels, and moderate or slight reactions with those 

 of whales. Anti-llama serum gives a moderate reac- 

 tion with the blood of the camel, and the close rela- 

 tionship between the deer family and the great host 

 of antelopes, sheep, goats and oxen is clearly demon- 

 strated. 



(5) Anti-whale serum gives maximum reactions 

 only with the bloods of other whales and slight reac- 

 tions with those of pigs and ruminants. 



(6) A close relationship is shown to exist between 

 all Marsupials, with the exception of the Thylacine, 

 or so-called Tasmanian Wolf. 



(7) Strong anti-turtle serum gives maximum reac- 

 tions only with the bloods of turtles and crocodiles, 

 with those of lizards and snakes the results are almost 

 negative. With the egg-albumins of reptiles and 

 birds a moderate reaction is given.
