          I have received the four published volumes of
 [Kenneth's Enumeratis Plantarium?] - and also the 8th of
 DeCandolle's Prodromus.  I have ordered the Supplementary
 work of [Walpers?] - and Buck's Index generalis -
 which I am told I may expect soon.  With these,
 & your N.A. Flora - if I should live to see them
 completed - I must endeavor to be content: for I
 cannot afford to indulge largely in books.  If I
 had all the aforementioned, however, complete, I should
 think myself pretty well provided.  I do hope you &
 Dr. Gray will endeavor to give us the remainder of the
 N.A. Flora as fast as possible.  It will do more for
 the science, in this country, than any other work; &
 I am very impatient to have it.


     I am very sorry to hear such an unfavorable account
 of the results of the exploring expeditions; but it is
 whiat I have been apprehensive of, for some time.
 The interests of science, I fear, will always fare
 badly in the hands of selfish politicians.


     I have had the pleasure of of reading Lt. Fremont's
 Report; but do not possess it.  It is exceedingly interesting.


    My object in writin this hasty scrawl, is merely
 to inform you of the poor little parcel sent, this
 morning to New York.  I hope you will soon
 receive it.  I shall always be most happy to
 hear from you, when your leisure permits - and
 remain very truly your obliged friend,
                                        Wm Darlington


 Dr. J. Torrey, Princeton, N.J.


 P.S. I have not had the pleasure to meet Dr. Gray, this
 season; but I hear from him, at long intervals.
