390 = T. Carnelley—Existence of Ice at high Temperatures. 
So far, I have only had the opportunity of completing the 
two following determinations, and in the second of these the 
weight of the ice could not be found, as a small quantity of 
water was lost out of the calorimeter, owing to a sudden jerk 
at the moment the ice entered it :— 
(1.) Weight of water in calorimeter, including the value of the 
latter =185 grms. 
Weight of ice dropped in =1°3 grms. 
Temperature of calorimeter before=13°4 
ey after=13°6 
Rise in temperature= 0°2 
8 po 6 
M(6—¢ ie —6) 
(185) x 0-2) +(80 x 1°3)=1°3(T—13°6) 
T=122° C. Where T=temperature of ice. 
(2.) Weight of water in calorimeter, &c.= 185 grms. 
Temperature of calorimeter before= 12-7 
“ oa after—12°8 
Rise in temperature= 0°1 
weight of the ice and therefore its temperature could not be 
ound. But since the calorimeter had slightly risen in temper- 
ve 80° C. : 
ature, the ice must have been abo 
the experiment, so that it might first attain the temperature of 
the room, while the time which elapsed between the readings of 
the thermometer before and after the ice was dropped in would 
not be more than from 10 to 15 seconds. 
n the course of the next few weeks I intend to make one or 
two more determinations, and if possible, on a larger scale.
