          My dear Sir,

 I had the pleasure this
 day of seeing Mr. Wm [William] S. MacLeay the
 Naturalist, who has just arrived from
 Cuba on his way to England : he was
 some years in N. S. [New South] Wales in government
 employ, & has really been an important
 contributor to science. He goes to Boston 
 tomorrow, & returns next week, when
 I hope to introduce him to you, but
 ad interim, I want to furnish him
 with letters to the men of science
 in Boston. Will you therefore favor
 me with letters for him to Dr. Jackson [Charles T. Jackson?],
 Mr. Greene [Benjamin D. Greene?] & any others of the right sort
 you may know there. I shall want
 them by midday, & my bro't [brother] will 
 take charge of them for me. Your
