Perhaps the most surprising testimony to the existence of an “epidemic constitution” of slow, continued nervous fever comes from the island of Barbados. Hillary, who had kept a record of the prevalent diseases at Ripon, continued the same when he settled in Barbados in 1751[224]. There can be no doubt as to the appearance of this fever in February 1753, its prevalence all over the island for eighteen months, and its disappearance in September 1754, when, as he writes, “It now totally disappeared and left the island, and, I think, has not been seen in it since” (1758). He gives the same account of it as the observers in England and Ireland, except that he does not describe miliary eruptions and describes jaundice in convalescent children. It was insidious in its onset (as in London), the patient often keeping afoot five or six days; the symptoms included pains in the head, vertigo, torpor, lassitude, vigil, delirium, faintings, partial sweats, involuntary evacuations, gulpings, tremors, twitchings, catchings, coma and convulsions. Recovery was marked by copious equable sweats and plentiful spitting. “This slow, nervous fever was certainly infectious, for I observed that many of those who visited, and most of them that attended the sick in their fever were infected by it, and got the disease, and especially those who constantly attended them and performed the necessary offices of the sick.” It was last heard of in the remoter parts of the island. Miliary Fever. It will have been observed in the foregoing accounts of the predominant fevers of the years (roughly) from 1750 to 1760 that there was often a miliary eruption, but that it was far from constant. The constant things were the lowness, depression, ill-smelling sweats, tremors of the whole body or of the wrist-tendons, and other nervous or ataxic symptoms. But we hear more of a miliary eruption in connexion with that than with any other period of fevers in the history; and this was the time when a controversy arose as to whether there was in reality a distinctive kind of fever marked by miliary eruption. Some of the school of Boerhaave contended that the phenomenon of miliary vesicles was due solely to the heating and sweating treatment of the alexipharmac physicians. De Haën and others answered that miliary fever was a natural form, independent of the mode of treatment. The Boerhaavian contention may be admitted as good for such miliary fevers as were described under that name in 1710 by Sir David Hamilton[225]; nearly the whole of his sixteen cases appear to have been made miliary by treatment, in so far as they became miliary at all. What this physician did was to foretell the approach of miliary symptoms in various maladies (about one-half of the cases being of lying-in women, and the rest various), and then to prescribe Gascoign’s powder, Goa stone, Gutteta powder, Venice treacle or other diaphoretics, along with diluents
