To L. BOUTON Esq., 
Secretary Royal Society of Arts and Sciences. 
My dear Mr. Bouton, 
I send you the paper we were speaking about yesterday. 
I am afraid you will find it more bulky than valuable, but if 
you think that it is not likely to interest the members of the 
Society, pray destroy it or do what you please with it. 
Yours very truly, 
J. R. MANN. 
7th February 1860.
