Thanks for his favorable comments on her book. Sends proof sheets as part of her forthcoming book on authors.
Reading proofs of JH's Essays Q. E. R.; working on an article on meteorology.
Sending a little joke on a political theme. Further regarding a query of JH's on a rabbit. Gives a problem on a polygon. Meteorology is peculiar as weather does not appear to be governed by any laws.
Is glad he likes the idea of projecting more than a hemisphere. Compares his own projection and a stereoscopic projection and comments on the results. Is now having another projection made that should give an accurate map of America.
