In 50 cases Bodin5 found more than one-half attributed it to othersaffected with the same disease; of these 29 were in schools, asylums, andhospitals; 10 were exposed to animals having the disease (mice, dogs, espe-cially the rat-terriers, cats, and more rarely fowls); in 10 cases it was impos-sible to trace the origin. It is said by Bodin to be a rural disease, occurringmost frequently in the country, and in cities largely confined to the suburbs.
