to find that soft iron would not last near so long as a hard 
and substantial iron, particularly as regarded steam-engine 
boilers. It was very well known that a boiler made from one 
description of iron would last eighteen or twenty years, and 
that a boiler made from another description would not last 
more than eighteen or twenty months, and therefore the pro- 
duction of iron of the greatest possible durability was an 
object of extreme importance, 
Mr. Embleton moved " That the best thanks of this 
meeting be given to Mr. Todd for his valuable communica- 
tion, and that the Council take into consideration whether 
they think it would not be desirable to recommend him to 
continue his experiments, not only on this iron, but on the 
Staffordshire and Scotch irons." He (Mr. Embleton) thought 
that Mr. Todd would be better able to come to a decision 
with respect to the merits of mixed irons than any other 
person. As yet, he had only tested the strength of two or three 
mixtures. It was a subject indefinite in extent, and it was 
probable that Mr. Todd might hit upon a mixture having the 
greatest strength of the Elsecar and Bierley bars, which 
averaged 30 cwts. He was of opinion, if a resolution to the 
eflfect he had mentioned emanated from the Society, Mr. 
Todd would gladly undertake the task of making the experi- 
ment. 
Mr. Hartop seconded the motion. 
The Chairman put the proposition, which was adopted 
unanimously. The Rev. Gentleman observed that their 
object ought to be to increase the strength of their own 
iron, rather than that of foreign production.
