It will give me much pleasure to show the two pictures of Jupiter, with what is apparently a shadow of the great red spot, on Monday evening.
I return from here Monday morning. I shall be at the Queens again. It is very kind of you to send for me and I shall be ready by quarter past seven -- or half past if that is time enough -- I will bring the slides with me. I have only a few instructions to give to the lanternist.
The thought has just occurred to me that I might possibly do a little good for your "Opera Glass Soc." by mentioning it in my lecture Friday afternoon. If you would like me to do this, will you please tell me a little about the Soc. and please tell me what details you can see on Jupiter & Saturn with an opera glass. I really have forgotten--I think this might be of interest to the young people.
