 Dear Sir,


 Should you attain
 any copies of your Botany of New 
 York, (Natural History N.Y) for which
 there are no more worthy applicants
 than myself, I should be extremely
 glad to obtain one for my library.
 I have nothing to offer you in exchange
 but the four additional
 volumes of my work, which can
 scarcely be regarded as equivalent.
 One of these days, perhaps, I may
 be better off.


 Yours very truly
 J.M. Gilliss


 Prof. John Torrey.
 New York.
