The relative frequency of infestation of the adult population with Trichinella spiralis has been readily demonstrated by postmortem surveys. The relatively infrequent incidence of clinical trichinosis must result, therefore, from our failure to recognize sporadic cases, as it can manifest itself frequently with unusual symptomatology.
A complete treatise on this disease is a valuable contribution to current medical literature. This is a well written work embodying several interesting features, including historical aspects, parasitology, pathology, epidemiology, clinical aspects, treatment and control measures. One must call special attention to the section on the morphology of Trichinella spiralis, which includes several excellent illustrations and magnifications of microscopic studies.
In the section on epidemiology stress is placed on the pernicious practice of feeding pigs uncooked garbage containing scraps of raw trichinous pork, thus maintaining the pig as a reservoir for further human infection. The cycle then continues when uncooked or undercooked trichinous pork or
