Thanks JH for recommendations [see JS's 1864-3-24]. Plans new section in Quarterly Journal of Science to review recent events in science. Shall avoid 'craving for novelty' evident in other publications.
Lady Herschel is valuable friend, having written to TW often in China. TW was to have 'bowed before John Steward' but postponed. Heard of JH's son's intentions from [Alexander Hamilton?] Gordon.
Just received photograph of JH, because Mrs. Gordon forgot to forward it. [E. R. W. Wyndham-Quin] Lord Dunraven is jealous and wants one too. Enjoyed visit of Mr. [Juetty?] and Mrs. Gordon.

In response to HS's query [1864-3-1] about the influence of Auguste Comte on English scientists, JH refers HS to JH's 1845 B.A.A.S. presidential address. States that calculating the motion of a projectile through a resisting medium is extremely difficult.
Announces son William's engagement to Emma Hardcastle; warns son John against the Anglo-Indian ladies; JH comments at length on a problem in surveying, and concludes with the news that daughter Francisca's health is improving.
