Not all horse doctors are veterinarians; at least not all horsey doctors are ecozoiatrists. M. Murray Nierman, an Associate of the American Academy of Dermatology and a professed reader of the Archives of Dermatology as well as the Daily Racing Form, has been victimized by dual loyalties, horses versus patients. The jacket of his recent literary effort, Patients and Ponies,1 confesses inoculation with the horse racing bug while he was still a student in medical school. My parents had led me to believe that this sickness was an hereditary malady and essentially as stigmatizing as syphilis or atheism. Although septicemia eohippus (Gr. hippos, horse) is reported to be incurable, many of those afflicted find it a lingering malady. I should have noted earlier that neither Nierman's skill as a dermatologist nor the scars on his horsebitten soul penetrated as deeply as his talents for satire and affection for travesty.
