RT Journal A1 Park WH T1 MEasles antiserum JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1929 FD March 16 VO 92 IS 11 SP 920 OP 920 DO 10.1001/jama.1929.02700370068033 UL http://dx.doi.org/10.1001/jama.1929.02700370068033 AB To the Editor:  —In the discussion of Dr. A. Clement Silverman's paper on "Serum Prophylaxis in a Measles Epidemic," read at the annual session (The Journal, Dec. 8, 1928, p. 1786), I stated that I had not had favorable results in a very limited experience with the Tunnicliff-Ferry measles antiserum. This antiserum was prepared by Dr. Ferry and sent me. Dr. Ferry does not believe that his organism is similar to Dr. Tunnicliff's, and therefore any lack of results in the few infants and young children from the Ferry serum does not in any way indicate that her serum is not of value. I combined the name Tunnicliff-Ferry serum with the idea of giving her credit, as I believe that the two organisms are practically of identical nature.
