It will be seen that there are definite reasons for rejecting the experiments 

 numbered 56, 59, 61-65, 68-72, and of the rest there are five only for which the 

 differences reach O'l mm., and the mean difference for the whole number (without 

 regard to sign) of those not rejected amounts to "077, or again less than '1 mm. 



12. Rejecting from Table VI. then the numbers indicated, and arranging the 

 observations in the order of humidity of the air, we get the following re-arrangement 

 of the Tables V. and VI. :- 



TABLE VII. 



The last four observations are not among those quoted in Tables V. and VI. ; they 

 were taken before the behaviour of the saturator and its difficulties were fully under- 

 stood. They are, however, observations for a very high degree of humidity, and in 

 such cases the peculiar difficulties of the apparatus do not come in ; they may there- 

 fore, I think, be fairly included in the table of final results.
