In a preliminary report,1 we presented the data of thirty-seven cases of bronchopneumonia, following the present epidemic of so-called influenza, treated with serum obtained from patients who had recovered from a similar pneumonia. Later, in an informal letter to The Journal, we2 advised the discontinuance of the compatibility tests, and other modifications to simplify the preparation and administration of the serum.
The present report gives as complete data as were obtainable in 151 cases at the Naval Hospital, Chelsea. This represents all cases of the foregoing type admitted to our wards since the treatment was started. For convenience and completeness, this includes the original thirty-seven cases reported.
In our preliminary report, we also noted that the severity of the disease was on the wane. Naturally, we wished for an opportunity to carry on the work in a field in which the severity of the epidemic was unquestionably great.
