*328 Mr. Hutchins's Experiments for ascertaining 
to 95 0 . I then made a frefh mixture, but it had no effedl any 
way during three quarters of an hour f attended to it after- 
wards. During this idle interval I made the third experiment. 
Finding no alteration, I went down to breakfaff, and on my re- 
turn was furprifed to find the quickfilver in the apparatus ther- 
mometer had fubfided into the bulb, and the flandard thermo- 
meter had been very low (how low I cannot tell), and was 
riling brifkly. The fpirit thermometer alfo fhewed the mix- 
ture had a lefs degree of cold than before. To be certain that the 
quickfilver in the apparatus thermometer was in the bulb, I 
took the apparatus out of the mixture, and examined it mi- 
nutely for half a minute, till I was quite certain of it; and 
alfo that the quickfilver in the cylinder was frozen, and it is 
remarkable, it did not liquify in all that time. 
The obfervations were made with the greateft attention, and 
(on every particular occafion) noted down as quick as poflible.
