JL wo Kssays on the Theory of Mixed Gases 

 and on the state of water in the Atmosphere, 

 have been read to this Society, the former in 

 1803, and the latter in 1804, having an espe- 

 cial relation to ray Essays on the same subjects 

 which were published in the Memoirs of this 

 Society, \'ol. 5. part 2. — Having formerly 

 had some conversation with the author of those 

 essays on the subject, in which I found his 

 sentiments did not accord with mine, 1 desired 

 him to commit them to paj>er, apprehending 

 that if any substantial argument against my 

 j)eculiar doctrine existed, he would lay hold

 Some time after this, the former of the two 

 essays /^page 296) was presented to the Society
