as deduced bij himself and Dr. Suerman.

The number in this latter table for oxygen was inferred 

 from that for nitrogen by formula (C), and the same may be 

 said of the number attached to carbonic oxide, which was cal- 

 culated in the same way from the specific heat of carbonic 

 acid and of a mixture of equal volumes of the two gases, as 

 deduced from experiment. From the care bestowed upon 

 the various manipulations, and the consistency of the different 

 observations in the same gas, I am disposed to look upon the 

 numbers given above as very close approximations to the 

 truth. I should probably except from this statement the spe- 

 cific heats ascribed to oxygen and nitrogen, as but three ex- 

 periments were made, in consequence of one of the gasometers 

 having begun to leak. Moreover as nitrogen was the gas 

 operated with, in passing by calculation to the specific heat of 

 oxygen the errors of observation would be multiplied by four. 

 Oxygen, in fact, not nitrogen, should have been the subject of 

 experiment.
