"Dr. A. F. Schafer. 
f “ Phylacogen ” (pronounced phy-lac'-o gen) is a new word—coined to designate a series of therapeutic 
agents which we are abo it to offer to the medical and veterinary professions. It is derived from two Greek 
words, the equivalent of “ a guard ” and “ to produce.” and means a generator of phylaxins—defensive proteid 
bodies developed in the blood of immunized animals.] 
The phylacogens are prepared in accordance with the method of 
Dr. A. F. Schafer, of Bakersfield, Cal., their therapeutic application 
being based on the theory of multiple infections. They constitute, it is 
believed, the most important biological preparations since the advent 
of antitoxin. ♦ + ♦
