Hillary, W.  Observations on the Changes of the Air and the Concomitant Epidemical Diseases, in the Island of Barbados (1759).

Hillary's most important work contains good accounts of lead colic and infective hepatitis, as well as the first description of the tropical variety of sprue or diarrhea alba, which chiefly attacks adults. 

William Hillary (1697-1763), English physician, received his M.D. in 1722 from the University of Leiden, where he studied under Dr. Boerhaave.  He is best known for his systematic studies of the effect of weather on prevalent diseases in Ripon from 1726 to 1734 and in the colony of Barbados from 1752 to 1758.
