and of those in whom respiratory complications developed, nearly
half died. Among the 2,674 cases of this disease treated during
the year, 71 cases of lobar pneumonia complications occurred
with 31 deaths.
As in the case of the previous year, tuberculosis continues
to hold first place in the morbidity and mortality among prisoners. Out of 179 cases treated during the year, 108 or 65.95
per cent died. The transfer of tuberculosis patients to Iwahig
Penal Colony, or elsewhere would improve the health of such
patients and prevent the spread of infection inside Bilibid Prison.
As a result of the influenza epidemic, the general death rate
and the death rate from tuberculosis showed marked increase
as compared with the rates of previous years.
In the annual general medical survey of the prison, 2,633
prisoners, including females, were examined physically and microscopically, and the results of the examination was as follows:

Incidentally, 39.08 per cent of the prisoners so examined were
found infested by intestinal parasites, a higher percentage than
the one given at the beginning of this article.
The general death rate for the year was 21.10 per 1,000,
figured on an average prison population of 6,926; of which 10.40
represent deaths due to non-tubercular cases, and 10.70 represent
those due to pulmonary tuberculosis. Of the total 146 deaths
occurring during the year, 137 were Filipinos, 8 Chinese and 1
American.
The comparative immunity of Bilibid from cholera infection
and the very small number of cases of beriberi registered during
the year, most of which were traceable from outside at that,
are convincing proofs of what iron-handed sanitation can accomplish in a given group of individuals. Our experience in sanitation work at Bilibid Prison is a standing lesson of tropical
