Would like to reprint JH's paper 'On the Projection of the Sphere' in their Educational Times. Can he supply a reduced diagram?
Thanks for the case of wine. Saw Alexander Herschel this morning and is getting some information from him. Has been on board the Warrior.
The Churchwardens of Hawkhurst are inviting JH to the Easter dinner.
About a request of JH for some palladium from the R.S.L.
Note to accompany sending of palladium [see GS's 1861-3-14].
Thanks for the palladium [see GS's 1861-3-22].
Claims to have demonstrated that light intensity increases as distance from light source increases. Applies this to inner planets, where sun should appear dimmer than on Earth. [JH annotation: 'Frivolous & Vexatious.']
Thanks JH for a memoir on the projection of a sphere. Expresses the wish that map-making, so neglected, be taken up thoroughly.
Discusses 'autograph of the sun' he sent earlier. Discusses measuring relative temperature of sun. Has an unpublished letter of Galileo to Cardinal Barberini regarding sunspots.
Reminds JH that the algebraic formulation of the theory of the achromatic telescope eyepiece was formulated by GA.
