1. " On a Smokeless and Self-feeding Furnace for Lignites and other Fuels, 

 and the Utilization of the Waste Heat," by Henry Skey. (Transactions, 

 p. 25.) 



The Chaii'man said he should like to have seen some pi^actical men there 

 that evening. There was abundance of coal in the Province, and it would be 

 a great benefit if it could be utilized as suggested by Mr. Skey. He was glad 

 the matter had been brought forward, for it was certainly worthy of very 

 serious consideration. He would ask the author if the principle could be 

 applied to dwelling-houses. 



The author replied that it could be so applied with certain modifications. 

 It was, however, principally intended for the raising of steam. As furnaces 

 were now constructed there was a very great waste of heat ; and the same in 

 the- case of ordinary fire-places, where a large portion of the heat escaped up 

 the chimney. It took about one-fourth the fuel to give the di-aught. Could 

 his principle be carried out, not only would one-fourth be saved in the value of 

 the coal consumed, but we should be able to use any species of coal or lignite 

 for domestic, and especially for steam, })urposes. But it was true that great 

 difficulties were in the way of utilizing heat in the way he had pointed out.
