Riverside, Cal. June 6, 1891.

G. E. Lumsden Esq.:

Dear Sir,—

Accept thanks for your favor of May 27, with the first annual Report. On p. 29, I notice what I suppose to be a typographical error.

On the 8th l. from the bottom for for Jupiter read Neptune, and on the 5th l. from bottom for axis read axial. It is not important, hoever, and need scarcely be noticed.

With much interest in the Society, I remain

Yours very truly

Daniel Kirkwood.
