Summary:

Is JH aware that the magnetic and meteorological observations now being made at Greenwich are to cease at the end of the year? As JH was zealous for these observations he may care to write to S. J. A. Compton (2nd Marquis of Northampton). It escaped his notice that S. D. Poisson and J. B. Biot referred to saturated steam. Return John Robison and Karl Holtzmann to Mansion House when he has read them. Has consulted Thomas Graham about repeating John Southern's experiments.

Summary:

Agrees with JH that the Government Observatories at the Cape and St. Helena require mature consideration. Greenwich observations are a different matter and were suggested by the R.S.L. Committee of Physics. Has directed the minute to be sent to JH. Has been studying the wet bulb question.

Summary:

The magnetic and meteorological observatories were never part of any other system. Is not certain whether the Visitors had anything to do with these observatories. Captain Herbert in an Indian journal has proposed a formula for the wet bulb thermometer. Has arranged for the notice to be sent to JH.

Summary:

The President was requested to write to the East India Company about the observatories. Continuance of the magnetic observations at Greenwich was referred to the Committee of Physics. Cannot find where Nicolas Clement-Desormes's observations are published. Has been studying the wet bulb problem. Capt. Herbert has denounced the article on hygrometry in Brewster's Encyclopaedia.

Summary:

Has been with Philip Melvill of the East India Co. discussing the printing of the observations. Would it be a good use of JH's photographic papers to take a reverse of William Parsons' (3rd Earl of Rosse) drawings of nebulae? Cannot obtain Nicolas Clement-Desormes's or John Sharpe's papers. Doubts if the mode of measuring latent heat hitherto used can be recommended for accuracy.

Summary:

Thought his letter had miscarried. Thanks for the gift of his recently published work [Cape Results]. Will be glad to supply any information from his own work on comets, which he hopes to send in the course of a few days. Is studying U. J. J. Leverrier's method of development by elimination.

Summary:

Regarding his own method of calculating the perturbations of the comets. Expense of computation is high for an individual and a mention by JH would bring support for his scheme. Would like to explain his method at an ordinary meeting in January. Every branch of science is facilitated by tables and those he suggests seem most desirable.
