Summary:

Much obliged for JH calling but regrets he was out. The question [on steam] they have been discussing seems to be answered by a paper by a Prof. Karl Holtzmann he has just come across; comments on this. If JH is coming to S. J. A. Compton's (2nd Marquis of Northampton) soiree will he come and dine at St. James' Place?

Summary:

Was not aware when he wrote his paper that doubt existed regarding the invariability of [the absolute heat of steam?]. Comments on the variations in the theories of S. D. Poisson and Karl Holtzmann. The experiments JH suggests would be highly interesting. Would he like to see Holtzmann's paper?

Summary:

Has no doubt that any improvements JH suggests should be published. [John?] Taylor has borrowed Holtzmann's pamphlet, which will be sent as soon as returned. Karl Holtzmann's formula for air appears quite out. Gabriel Lamé evades the question. If JH writes anything on his calorimeter hopes he will mention the various questions raised.
