 and attention, and as their results are both curious and 

 important in several respects, I have thought them de- 

 serving of being made known to the public in all their 

 details. 



An Account of three Experiments made at Munich, the loth October,

Contents of the boiler, when quite full to the brim, 14,163 Ibs. Bavarian 

 weight of water, at the temperature of 55, equal to 17.540 Ibs. avoirdu- 

 pois, or 2099 wine-gallons. 



The boiler actually contained of water, in the beginning of each of the two 

 following experiments, in Bavarian weight, 8120 Ibs., equal to 10,056 

 Ibs. avoirdupois, or nearly 1204 wine-gallons. 



The wood used in this and the following experiments was pine, which 

 had been moderately seasoned ; and the billets were 3 feet 4^ inches, Eng-
