A glance at Table 7 shows that the control died and the others lived. 

 Control animal No. 33 gave a good reaction for cattle plague and died 

 on the twelfth day after inoculation. Of the five Indo-China heifers, 

 only one. No. 35, gave a good reaction. On inspecting the temperature 

 charts, it will be noticed that the dates of chart 33 do not correspond 

 to those of cliarts 34, 35, 36, 37 and 38. A suitable control animal 

 was not at hand when animals 34, 35, 36, 37 and 38 were inoculated. 

 None having died, and only one having reacted well to the first inocula- 

 tion, they were reinoculated with 5.0 cubic centimeter of virulent blood 

 each, and the control animal. No. 33, received 0.5 cul)ic centimeter of 

 virulent blood. (See charts 33 to 38.) 



TliST 8. 



Anticattle-plague serum No. 891, prepared in the Philippine Islands, 

 was tested on Indo-China heifers, Nos. 40, 41, 42, 43 and 44, each 

 weighing about 100 kilograms, controlled by Batanes Inilloek No. 39. 

 All were inoculated with 0.5 cubic centimeter of virulent blood, and 

 animals Nos. 40, 41, 43, 43 and 44 received 10, 30, 30, 40 and 50 

 cubic centimeters of serum.
