348 TRANSACTIONS OF THE AMERICAN INSTITUTE. 



Mr. Churchill— I understood Prof. Seely to say that many of the hydro 

 carbons in burning would necessarily smoke. I made a great many experi 

 ments witli lamps while on the committee last winter, and I have continuec 

 them since, and I think there is no fat that cannot be burned without smok( 

 in a still atmosphere, if the lamp is not moved about. 



Prof. Seely. — You must have misunderstood me; I agree with yoi 

 entirely. 



The Chairman. — There are a few minutes left; will any one make any 

 remarks or ask any questions ? 



I will inform the society that I shall leave the country in a few daya 

 for Europe, and I shall regard myself as a sort of traveling agent of the 

 society at my own expense. I shall try to learn everything of interest to 

 this Association, especially the working of similar societies, Avhich I shall 

 communicate to you on my return, as occasion may offer. Since I have 

 had the honor to preside over your meetings, I have become exceedingly 

 attached to the work. I shall be absent five months, and perhaps you 

 ought to take some steps to provide a presiding officer during my absence. 



Mr. Dibben.— Mr. Chairman, during the summer months it has been our 

 practice to discontinue our meetings, and in the few meetings that we shall 

 hold during your absence, we can choose a chairman pro tern. 



On motion of Mr. Fisher, the thanks of the society were voted to the 

 Chairman for the firm and satisfactory manner in which he had presided 

 over the meetings. 



The subject of "Superheated Steam" was chosen for the next meeting, and 

 the society adjourned for two weeks.
