Single-source entries: Z (9)

These 2 listings are so strange that each appears in only one of the 7 encyclopedias we compared. They include such classics as Zygospore, Zymotic Diseases.

The chief of these diseases are measles, scarlet fever, smallpox, typhus, typhiod, diphtheria, whooping cough, croup and erysipelas.
