          by indulging any scientific request you may be pleased to ask 
 of them. 

 I rejoice at the prospects of your new pursuits.
 Your monograph of Carex formerly amused us greatly, &
 He among us was considered the best tactitian who 
 could make his plant (or species) accord to the catalogue; 
 it is however by far the best ever presented. I know that there
 are many more of the Cyperaceae, in the district, than are noticed
 in the Prodromus: for many were left undecided from want
 of maturity and other causes. As to the Grasses,
 if you have not a copy of Beauvois, mine is at your 
 service, as well as any other work in my possession. 

 Your forthcoming general synopses we shall 
 all be gratified to see, a work that there can be
 no doubt, will [added: add] much to the [added: scientific] literature of our common 
 country. God speed & protect it. 

 Have you seen any numbers of the "Supplement 
 Hortus Britannicus of London" except no. 1 which is 
 published in his edition (first) for May 1830? He promised
 that one should be issued annually on the 1st January. 
 My copy is becoming very racketty, & wants the helping 
 hand of the Binder, but I've been daily waiting for the 
 Supplements. 

 I have some "botanical disquisitions", which I will 
 reserve for future correspondence, & I am sure it 
 will afford you amusement, if not information. It 
 is the decision of arbiters puzzled (Rafinesque and
 Darlington) on one of the most, I might almost say, 
 simple genera, "Gentiana". More anon.

 Were you ever perplexed with Rafinesques
 "Divitial invention"? If you have not, I can hereafter
 give you some information on this subject, if desirable, 
 for you must know that I have had the honor of 
 being appointed an "Agent."

 I am Sir very respectfully 
 & truly yours 

 J.A. Brereton

 Dr. J. Torrey.

 P.S. The augmentation of the table of "Errata" in the
 Prod: [Prodromus] occurred during an absence from the press, on occasional 
 duty from Washington, and on return corrections were
 irremediable except its exposure as a finale.
