LX VI I. An Account of the extraordinary 
Heat of the Weather in July 1 757, and 
of the Effe&s of it. In a Letter from 
John Huxham, M. D. F. R. S. to Wm. 
Watfon, M. D. F. R. S. 
Find by your letter, that the heat at 
London was not fo great in the be- 
ginning of- July 1757, as at Plymouth by two or 
three degrees of Fahrenheit’s thermometer. We had 
again, after much rain at the clofe of the month, and 
in the beginning of Auguft, exceflive heat • viz. on 
the 8th, 9th, and 10th of Auguft ; which mounted 
the mercury in that thermometer to 85 ; nay, on the 
9th, to near 8d. I never before remember the mer- 
cury in that thermometer to exceed 84 ; and that is 
even here a very extraordinary degree of heat. 
The confequences of this extremely hot feafon 
were haemorrhages from feveral parts of the body j 
the nofe efpecially in men and children, and the 
uterus in women. Sudden and violent pains of the 
head, and vertigo, profufe fweats, great debility and 
oppreftion of the fpirits, affedted many. There 
were putrid fevers in great abundance ; and a vaft 
quantity of fluxes of the belly both bilious and 
bloody, with which the fevers alfo were commonly 
attended. Thefe fevers were always ufhered in by 
ievere pains of the head, back, and ftomach ; vomit- 
ings of green and fometimes of black bile, with vaft 
oppreftion of the prcecordia , continual anxiety, and
