(2b) Parasites rarely reported from man. which normally occur in animals, and which are largely of academic interest. (1) . Larval parasites of animal origin which can infect mar. and often cause serloua disaaae* Under each.of the above beading! the author has discussed several species with regard to their his torical significance, geographical distribution, host specificity, life cycle, method of Infection, the disease produced, sad the method of treatment, if any exists. He also discusses some of the preventive measures that are in existence or might be undertaken to control the spread of these perasites.
