geration will abfolutely deprive ice of all its 
heat? *€ The degrees of heat neceffary to melt 
ice as are 130, and the fpecific heats of ice and 
water areas g to 10: then the number 130 
multiplied by 10, produces 1300, and divided 
by 1, which is the difference between g and 
10, quotes the fame 1300: therefore, if ice were 
cooled 1300 degrees below 32°, or to 1268 of . 
Fahrenheit’s fcale, it would retain nomore heat.”

BIOGRAPHICAL ANECDOTES OF 
THOMAS WoORLIDGE. 
SHOMAS WGORLIDGE, a painter, 
much admired fcr his defigns, was 
fettled at Bath for fome time, where he 
met with that encouragement which 
induced him, at length, to try the effect 
of his talents in the metropolis, that mart 
where genius, fooner or later, finds a re- 
ward, if not an adequate one, for its 
exertions. It is with concern, that I can- 
not gratify a laudable curiofity in afcer- 
taining the place of his birth, or in giv- 
ing any account -of his education, -or 
where he firft commenced the career of 
an ingenious profefiion. 
At Bath, however, he married a young 
woman, then extremely beautiful, the 
daughter of a perfon who kept a toy-fhop 
there, by whom he had two fine boys, 
who were educated at Bruges. This fe- 
male was very ingenious, and caught a 
love for the art, which fhe praGtifed with 
fome fuccefs after his deceafe, aided by 
the reputation of her conneétion with 
him. Her works were chiefly confined 
to portraits, and copies from her hul- 
band’s drawings. The king of Denmark 
noticed her performances, when he was 
in England ; but I have heard her fay, 
left the kingdom without giving her thote 
pecuniary acknowledgments which fhe 
had fanguinely expeéted. Genius, in 
deed, feemed to pervade the houfe; for 
there was an old Italian footman, who 
was very ambitious of exhibiting fome 
defigns which, as might be expeéted, 
difplayed much redundancy of fancy, 
with a very fimall proportion of tafte. 
Of our painter’s relations, there were 
only two that were remarkable: one of 
them, an officer in the Spanifh fervice, 
avery genteel man; and the other, a 
blind gentleman, whofe chief amufement 
was the theatre. ‘The ear was gratified, 
though there was no eye to receive enter- 
tainment. 
Covent Garden, which has attracted 
fo many men of diftinguifhed talents, 
was the place where this artift frft exhi- 
bited his productions, about the year 1743, 
when painting met with very fimall, if 
any, encouragement inthis country. The 
limners, as they where then called, were 
employed now and then te take the like~
