Sarah Faraday to John Tyndall   Either 1857 or 1863

Royal Institution

Dear Dr. Tyndall

Can you not come up to us for an hour or two (now we are all pretty well) and give us the pleasure of your company? to day will suit us, or to morrow if you like it better - come to tea or at tea time, and you shall have your choice of a slice of beef or a mutton chop with it. I would say come at our dinner time 2.30. but that does not suit you so well and we do not get such a nice time for chat, but at any rate come, and believe me

Very sincerely yours | S. Faraday
