 ten inches long, and of such a width as to allow of the 

 insertion of the bulb of the thermometer wrapped up 

 as described above, together wich the attached. scale. 



The results of these four experiments may be seen 

 in the following table ; and that they may the more 

 easily be compared with those made with the same 

 quantity of the substances, but differently disposed, I 

 have placed side by side the results of the comparative 

 experiments. 



It would carry me too far if I brought forward 

 in detail all the experimental results obtained in my 

 researches undertaken to investigate the manner in

 present I have indicated clearly, not only the course
