ere thefe ftudies, in which ufe and araufement are fo intimately blendcdj, 

 can be carried, into full efFedl. 



But in the iatcrirrij let the American philofopher do what is: in his. 

 power i let hinn fcarch the ill-explored feas, lakes, rivers, and forefts- 

 of his country; and his labors will be amply repayed. The tra£b: 

 between the Allegany or Appalachian chain and the ocean, will for the- 

 prefent be ample field for the moft adventurous naturalift. Let me 

 entreat him to be expeditious, that I may have fome chance of receiving 

 ■the pleafure of knowing that I could animate any one to thefe laudable 

 purfuits. But my eledtrical fire is too weak to be felt at fuch a diftance :; 

 I want the potent emanations of a Linn^us, which dartfrom pole to

 fortunate enough to have met with, at home and abroad, fome excellent 

 conduftors, which have caught and carried on the impulfive ftroke ; 

 which have at left' roufed natural hiftory from the palfied ftate into 

 which it was falling, on the lofsof its.illuftrious fupport. 



I muft myfelf have been very negligent, in the moment I forgot an ac- 

 knowlegement to the Reverend Mr. William Coxe, for the great fervices. 

 he rendered to me by his various communications refpefting Ruffia., 

 and other northern countries: Ihope he will receive this late refpeft; 

 with proper, allowance for my forgetfulnefs.. 



Mr. Samuel Oedtnan of Wermdon., near Stockholm., with the utmoft li- 

 berality, fpontaneoufly fent to me a number of vahiable remarks on the 

 qtiadrupeds and birds oi Sweden, which the reader will receive the benefit 

 of in the courfe of this work. 



I muft thank the ingenious Mr. Ld'«/d'K, late o?' Goettlngen, and at 

 prefent engaged, as metallurgift in the vaft copper- works in my neigh- 

 borhoods
