The unnatural conditions necessarily following the Concentration 
January 1st.in Batangas ancj. Lagupa,prompted General Bell to order, 
January I6th.,a universal vaccination of all natives in the protected 
zones. 
The Insular Board of Health,cooperating readily,furnished virus 
in abundance,and paid for the services of BO native vaccinators,who 
operated with corps .men and soldiers,under the provisions of the 
Surgeons at 28 garrisons in the two provinces. 
Most surgeons were occupied in this work till the end of Feb¬ 
ruary. Some interior points however with large populations,and delays 
in shipment of virus,were not finished till March I4th. 
A total of nearly 300,000 natives vaccinated has been reported, 
as follows.

The glycerinated caribou virus,provided by Major Maus,Commis¬ 
sioner of Health,came in tubes of 100 units,which usually proved suf 
ficient to inoculate 200 scarifications.
