While working through this fascinating booklet of "programmed instruction" on allergy and hypersensitivity, I kept wondering how much I would learn from the exercise if I were as unschooled as the average layman on the subject matter. The answer came from a friend who for business reasons was trying to gain a conversational knowledge of allergy. He found the material largely beyond his ken until he had read a popular treatise on allergy prepared for the general practitioner. Thereafter, the "programmed instruction" booklet became much more informative and instructive for him. On the contrary the exercise was fun for me. It taught me several facts which I had never known, offered a splendid review of practical allergy and hypersensitivity, now and then caused a raised eyebrow, and in a few areas stirred up objections which I must air.
To avoid picking at knits my negative criticism will be limited to
