Such was the refult of thefe experiments, from which I leave 

 it to you to draw concluiions. I intend to purfue them again 

 this winter ; and, if you can fuggefl any ideas on the fubject 

 that can reach Canada before March 1 7 86, I fhali be glad to 

 avail myfelf of them.

REMARKS on the preceding Extracl by Cha. Hutton, LL. D. 



From thefe ingenious experiments, we may draw feveral 

 conclufions. As, 







Firjl s We hence obferve the amazing force of the expannon 

 of the ice, or the water, in the act of freezing ; which is fuffi- 

 cient to overcome perhaps any refiftance whatever ; and the con- 

 fequence feems to be, either that the water will freeze, and, by 

 expanding, burft the containing body, be it ever fo thick and 

 ftrong ; or elfe, if the refiftance of the containing body exceed 

 the expanfive force of the ice, or of water in the act of freez- 

 ing, then, by preventing the expanfion, it will prevent the 

 freezing, and the water will remain fluid, whatever the degree 

 of cold may be. 



The amazing force of congelation is alfo obvious from the 

 diftance to which the iron plugs were projected. For, if we 

 confider the very fmall time that the force of expanfion acts on 

 the plug in pulhing it out, and that the plug, of 2| lb. weight, 

 was projected with a velocity of more than 20 feet in a fecond
