Carnivorn. Bloods from !» species: Tiger, Caracal, Genetta, Dog (U"/,,), Kaccoon (3"/,,), 

 Cat and Bear (4<'/„), Otter and Jackal (7 and S"/,, respectively). It was noted at the 

 time that the last three bloods were viscid or thick, doubtless concentrated. 



Rodenthi. Three bloods examined, from the Agouti, Rabbit, and Guinea-pig (0 "/(,). 



Im^ectivora. One blood examined, that of the Tenrec (0"/o)- 



Marsiipiulia. Seven bloods examined (0 *'/„). 



If we exclude the bloods which were regarded as concentrated wc 

 have 23 non-ungulate bloods of which 8 gave a 4"/o reaction, and 2 a 3 7o 

 reaction, all the others yielding no precipituni. 



Tests with Anti-Ox Herum (15. il. '02). 

 Antiserum from rabbit treated with the st'runi of Bos huvis, the 

 domesticated Ox.

In the above tests threo sheep sera gave the same figure, these 

 having been obtained on ditierent dates (19, ill. '01, sealed in tubes, 

 4, I., and 10, I. '02). Two other sheep sera preserved since 19, ill. '01, 

 the one dried in scales and brought into solution for the experiment, 

 the other preserved with chloroform, gave a precipitum of "003 and •0035 

 respectively. The ox and sheep sera were from animals slaughtered in 

 Cambridge and presumably normal. Whereas granules formed in the 

 solution of ox serum soon after the addition of antiserum, a cloudiness 

 persisted for over three hours in the other bloods. Compare these 

 percentages with those of the corresponding series with anti-antelope 

 serum, which follows. 



Tests witJi A nti- Antelope Senan (6. vi. '02). 

 Antiserum from rabbit treated with the serum of Cobus unctuosus 

 (48G).
