From a survey of available literature it appears that the blood of normal horses has been studied much less extensively than the blood of human subjects, and also that the work on horse blood has been limited to only a few types of analysis. The routine examination of the blood of all horses received at the laboratories, prior to immunization, is necessary not only as a part of the inquiry into their physical state, but also that subsequent comparisons may be made during the course of immunization. Much material is thus afforded from which considerable information may be gained. It is the purpose to present in part I of this report data that have been obtained from groups of horses which are fairly representative of average normal farm and city horses in apparently good health. [Part 2] The useful purpose that horses serve towards the passive immunization of man against certain infectious diseases is well recognized. The object of this investigation was to obtain evidence as to the effects of injecting horses with the various types of antigens and of subsequent bleedings.
