          Sir,

 Professor Agarth, of Lund, from whom you will find a letter
 accompanying this, in informing me of the desire that you have
 expressed to him of entering into correspondence with a mineralogist
 in this country, wishes me at the same time to tell you how sorry he
 is that he will have to be deprived of the pleasure of complying
 your wishes, not knowing any person sufficiently [crossed out: ?]
  [?], never decent, fit or learned to address you.
 As the last resource, he proposed that I should establish with you
 the correspondence you desire. From the little progress I have
 made in mineralogy, I ought not to accept the proposal however
 agreeable it is to me; but my zeal for the science will 
 not let me see calmly so favourable an opportunity as [?]. My
 intimate correspondence with Mr. Berzelius, of whom you
 have undoubtedly heard and who will soon obtain a celebrity
 in mineralogy equal to that which he now enjoys in chemistry, 
 has put me in a way of being perhaps useful to you
 in some shape. It is in combination with him that I
 think of entering into correspondence with you for I
 regret that I am at the commencement of the sciences
 which I have only pursued the last year after my retirement
 from my public service, and it is to be feared that 
 I will always be beginning in sciences which 30 year
 study but finds us beginning.

 It will be well for you to have some mercantile
 house in England as your country, when I will [?]
 direct the productions of Sweden, which I hope to be
 able to [send you?] those which you intend to [lend?] may
  be directed to Mr. [?] Merchant Gottenburg

 As I have introduced Mr. Berzelius to you
 I take this opportunity of mentioning his new
 system of mineralogy which he published this [?]

 During the time he was there he has also
 published another work, it is an essay on the theory of
 chemical proportions and the chemical influence of
 electricity. I would have written to you in your 
 language but [indecipherable phrase?]
