Upon the 15th, about feven at night, at Fal- 
“ mouth, Penryn, Truro, and thereabouts, a pretty 
“ fmart (hock of an earthquake was felt, attended 
<c with a hollow rumbling noife, throwing down 
“ pewter, china-ware, and fuch-like. The tinners 
“ felt it eighty fathom under ground. No great 
u damage however was done. The day before we 
“ had, about eleven o’ clock before noon, a mofl 
<c violent hurricane, which lafted five or fix minutes, 
“ attended with a heavy fhower.” 
Thus far Dr. Huxham. 
The heat of the air at London, during the period 
above-mentioned, was much greater than has been 
ufually obferved in thefe high latitudes ; tho’ it was 
never quite fo fevere here as at Plymouth. The fol- 
lowing table exhibits the degrees of the heat, taken 
here upon the refpeftive days, about four o’ clock in 
the afternoon, by a Fahrenheit’s thermometer. The 
inflrument was placed in the fliade ; and the accuracy 
of the obferver, who favoured me with his minutes, 
is not to be queftioned.
