“ generally very warm, and fometimes exceffively 
<c hot. From the 7th to the 14th of this month 
<( the heat was violent ; greater, indeed, than has 
'* been known here in the memory of man. I 
“ have talked with feveral perfons, who have lived 
“ a confiderable time in Jamaica, Gibraltar, and 
“ Minorca j and they feverally affert, that they ne- 
<e ver felt fuch intenfe heat in any of thofe places. 
“ Upon the nth, 12th, and 13th of this month, 
“ Fahrenheit’s thermometer, in the /hade, about 
“ three o’ clock in the afternoon, was at 87 ; nay, 
“ upon the 12th it was even above 88. 
“ Abundance of people have fuffered very feverely 
“ from thefe exceffive heats : putrid, bilious, pe- 
<e techial, nervous fevers, are exceedingly common 
* c every-where. Dyfenteries, haemorrhages, mod 
“ profufe fweats, afted; not only thofe in fevers, but 
“ a vafl: many others. The days and nights were 
“ fo intolerably hot, that little or no flcep was to 
“ be gotten day or night. The wind we had, like 
“ the Campfin, actually blew hot, tho’ ftrong. 
ROM the beginning of June Iaft 
we have had a very dry feafon.
