Mr. E. H. Griffiths on the Influence of 

 Table VI. 



Col. I. gives the capacity for heat of calorimeter +358*20 grms. (in 



vacuo) of aniline. 

 „ II. gives the capacity for heat of calorimeter -f 56953 grms. (in 



vacuo) of aniline. 

 „ III. is the difference between the numbers in Cols. I. & II., and is 



therefore the capacity for heat of 211*33 grms. (in vacuo) of 



aniline. 

 „ IV. the specific heat of aniline at the respective temperature?. 

 „ V. the water-equivalent of the calorimeter.

T 

 Experiments 1 to 5 give j =23205 (Table V. supra) when 



M 3 = 294-99, and 6 1 =11°'7S C. From the above table we 

 get 1^ = 80-01 when ^=17°-78. 



Hence 



S 1 M 3 +ic 1 =232-05 

 w 1 = 80-01 



.-. S!M 8 = 152-04 hence S 1 = -5154 (c/. with -5146 supra). 

 Again, the early experiments with water (p. 57) gave : — 

 when 1 =17-2 1^=80-1 



an d 1= =17-2 ^ = 79-8 



hence when ^=17-2 tcj= 79-95 [cf. with 79*99 supra) . 



Although I have referred to experiments 1 to 5 as un- 

 satisfactory in themselves, the value obtained from them is 

 (as above pointed out) in fair agreement with that deduced 

 from the remaining experiments. 



The same remark applies to the absolutely independent 

 determinations of the water-equivalent when conducted with 

 water itself, and they afford strong corroborative testimony 

 as to the accuracy of the conclusions,
