320. Autogenous vaccines.--Eighteen autogenous vaccines were prepared during the year.
321. Cholera vaccine. The presence of cholera again this year required the production of large quantities of cholera vaccine. This was prepared from strains isolated in the early summer from local cases. A sufficient supply was accumulated to take care of the requirements of next summer. In point of fact, 215,000 c.c. were prepared of which 20,140 were issued.
322. Anti-rabic vaccine.-Twelve animal brains were examined for rabies. Only one dog was found to be rabid. The table showing the distribution of the treatments given shows a large increase in the number of treatments completed, a gratifying point.
