Thanks JH for birthday wishes for JH's aunt Caroline Herschel. Goes on to tell JH about Caroline's health, both physical and mental, and about the birthday celebration for Caroline.

We will drink to your health on June 9, the day on which #600 of the Astronomische Nachrichten will appear.

Has heard JDH does not return until tomorrow, so will not be able to see him at Kew but hopes to do so at Oxford meeting of BAAS.

Bunbury and Falconer strongly against idea of coal being submarine.

Elated to learn from JH that JH has the remaining proofs of JH's preface to N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere, as WS had believed; he also is thrilled that Richard Sheepshanks, who asserted that WS held the proofs, will now have to eat his words!
