    From the foregoing tables it will bo seen that our late epidemic, in its prevalence and virulence, had two maxima, which were divided by the year 1840. In fact, from the gradual diminution of virulence in the intervening period between the maxima points, it would seem as if our last had been a double epidemic. In the last six months of 1840 there were but 14 deaths out of 613 total admissions into the Seaman's Hospital; or 9 deaths out of 225 yellow fever cases. This interval contrasts strongly with the more abrupt lull which occurred in December, 1837, and beginning of 1838. It is also seen that the epidemic has been subject to the ffeneral laws which influence the pi-evalence and virulence of febrile and other colonial disorders generally, as respects months, and that the vernal equinox through all conditions persists in being the healthiest period of the year.* The termination of the epidemic Avas preceded by the pre- valence of the simplex form, denoting that the virus had become gradually weaker; till, at last, in the great rainy season of 1845, it entirely ceased, superseded by a slight, but a very general influenza.f * [The following Return of Deaths from Fever, in Barbados, is given for the purpose of comparison; the accordances do not require to be pointed out, whether as to duration, fluctuation, or apparent influence of season.
