§ 5. Examination of the Vapour of Chloroform. 

 As the second fluid I took chloroform ; daring the examination 

 of this, in order to avoid the chemical influence of light, I 

 covered the side of the bath which was turned towards the win- 

 dow with a piece of yellow glass. For this preparation, as well 

 as for the bisulphide of carbon, which will be discussed further 

 on, both of them perfectly pure, I return my best thanks to Dr. 

 Glaser. The following Table gives the numbers for chloroform, 

 obtained in the same manner as those given for alcohol : —

The air-bubble amounted in this case to 0*3 1 cubic centim. 

 at 0° and under a pressure of 760 millims. The weight of the 

 chloroform examined was *1406 grm. The final constant vapour- 

 densities calculated therefrom are, for the different temperatures, 

 the following, which agree sufficiently : —

These vapour-densities differ more from the theoretical one 

 (4*138) than can be accounted for by small errors in weighing. 

 Indeed I think I remarked for some hours (before the beginning
