The preceding table shows that large reactions only occurred with 

 two samples of the blood of two animals of the species Auchenia 

 huanacos, the blood of one of which was used for the treatment of the 

 rabbit yielding the antiserum. The blood of Auchenia glaina and 

 Gamelus dromedarius gave x reactions. The percentage of reactions all 

 told, is larger amongst the Ungulata than among the other mammalia. 

 Again the Primates and Carnivora stand out among these.
