treatment only. Here again, as in the case of the cattle, the deaths 
after serum treatment were higher than we might have wished, because 
some of the animals were in the incubation period of the disease when 
inoculated, but at the same time, the mortality was not so great as it 
nught have been had serum not been used, which is taken as an evidence 
of its curative power. This subject will be dealt with below. 
During the same period, from January 1 to August 31, 1903, 1,494 
animals in the provinces received simultaneous inoculation; 42 of these 
died, a death rate of 2.8 per cent. Of 776 which were given serum 
inoculation, 48 died, a death rate of 6.1 per cent. Here again, the 
curative value of the serum must be taken into consideration in ex- 
plaining the percentage of loss among animals receiving serum only, 
for undoubtedly many more were infected with rinderpest than suc- 
cumbed to the disease. 
During the succeeding year the task of inoculating in the provinces 
was transferred to the veterinary corps of the Board of Health, so that 
the records of the laboratory cover but part of the period included 
between September 1, 1903, to August 31, 1904. 
These records show that between September 1, 1903, to June 15, 
1904, 3,117 provincial inoculations were undertaken by the simultaneous 
method, with a mortality of 4.09 per cent; 4,464 with serum alone, 
with a mortality of 0.11 per cent, or a total mortality for both classes 
of 1.76 per cent. 
During the months from April to August, 1903, there were 1,402 
animals inoculated with serum or with blood and serum on the Island 
of Tablas. The records of 1,128 cases are complete and show that of 
907 inoculated by the simultaneous method but 6 died, a mortality of 
1.18 per cent, and of 621 to which serum alone was given 35 died, or 
5.63 per cent. Here again, as in the previous instances, there is some 
evidence of the curative value of serum. 
The results of an attempt to immunize American cattle which were 
shipped to the Islands for dairy purposes were disastrous, probably 
because of their extreme susceptibility. (See Chart 15, No. 10, and 
Chart 16, No. 2.) Upon their arrival in the Philippines all of them 
received 200 cubic centimeters of a serum, 30 cubic centimeters of 
which would protect native or Chinese cattle against the inoculated 
disease. About twelve days later, some of these American animals 
received the simultaneous inoculation—i. e., 30 cubic centimeters of 
serum and 1 cubic centimeter of virulent blood. In any case, whether 
they received virulent blood, or simply serum, all but a few sickened 
and died of rinderpest and this in spite of early and late subcutaneous 
and intravenous injections of serum. Indeed, one animal beside the 
original dose of 200 received 730 cubic centimeters of serum (in all
