It is seen that the difference in the boiling-points in both series is about 

 24° for each increase of CH^ ; and further, that the boiling-point of a mem- 

 ber of the first series is the same as the boiling-point of that member of the 

 second series which contains CH^ more.

 expedition I shall be able to amend my omission of measuring the hill south 

 of Fairhaven*, which surely will furnish an excellent datum for determining
