 latiDg." 



Also to add after the word "burning," the words "and deo- 

 dorizing" — making it read, " burning and deodorizing coal oil." 



The Chairman said he would report any suggestions that might 

 be made by members of this association, to the board of managers 

 of the Institute, Amendments of course could only be made by 

 them. 



The revised list of premiums Avill be given at the next meet- 

 ing. 



KEROSENE LAMP WITHOUT A CHIMNEY. 



Joseph Thomas exhibited a lamp for burning kerosene or 

 Petroleum oil without a chimney. The principle of this improve- 

 ment consists in getting an extra quantity of oxygen, in the form 

 of heated air, to the flame. The great quantity of carbon in the 

 coal oil requires this. The lamp will burn common coal oil of 

 45 degrees of purity — and even as low as 32 degrees — without 

 danger of explosion. A safety valve is adapted to the lamp to 

 make it secure. The inventor claims that — 



1. No chimney is needed on the lamp, thus saving constant 

 expense and annoyance. 



2. That the smoke and unpleasant odor, so offensive when oil 

 is used in the ordinary way, are effectually prevented. 



3. That a clear and bright flame is obtained without increased 

 consumption of oil. 



4. That the burner can readily be applied to any ordinary 

 lamp. 



CRANK MOTION. 



The subject of the loss of power by the crank motion in steam 

 engines, was discussed by Messrs. Warren, Rowell, Fisher, Till- 

 man, Babcock, and Dibben, without eliciting any novel views or 

 arguments.

 of a protective tariff on national prosperity ; proposed by Mr,
