As table 3 shows all the animals died succumbing to cattle plague. 

 Serum No. 810 was below the average in immunizing value. (See 

 charts 10 to 14.) 



Test 4. 



On the 6th day of July, serum No. 810 was tested on eight native 

 carabaos, Nos. 15 to 22. All received 0.5 cubic centimeter of virulent 

 blood, No. 15 was used as control, and Nos. 16 to 22 received 75, 100, 

 100, 125, 125, 150, and 150 cubic centimeters of serum, respectively.

All animals underwent good reactions and as is shown in Table 4, 

 animals Nos. 15 and 16 died, Nos. 17 to 22, inclusive, lived. Carabaos 

 appear to be more resistant than the Batanes cattle to the disease. (See 

 charts 15 to 22.) 



Test 5. 



Batanes bullocks Nos. 23, 24, 25, 26 and 27 received 0.5 cubic cen- 

 timeter of virulent blood each. No. 23 was used as control and Nos. 

 24, 25, 26 and 27 received 25, 50, 75 and 100 cubic centimeters of 

 serum No. 872.
