Controversy betvoeen W, Sxvainson, Esq. F.R.S. L.S, SfCj and 

 N. A, Vigors, Esq, A.M. F.R.S, Sfc, 



My dear Sir, 

 My absence from England for some weeks past has prevented me from 

 seeing, until within these few days, a letter from Mr. Swainson, printed in 

 your Vol. IV. p. 481., professing to be a reply to my letter to you of 

 the 20th of June last. (Vol. IV. p. 319.) I consequently have not time 

 to take the notice I should wish of that letter in your forthcoming Num- 

 ber ; more particularly as matters of greater interest than any subject con- 

 nected with Mr. Swainson call at this moment for my undivided attention. 

 I shall however resume the subject in your next publication. In the 

 mean time my cause will suffer nothing from the delay. Your readers have 

 already before them Mr. Swainson's unwarranted attacks upon me, as 

 advanced in his original letter of the 13th of December, 1830 ; as well as my 

 answers to them in my letter of the 20th of last June : and they can 

 judge for themselves, without any additional observations on my part, 

 whether I have not given a full and triumphant answer to every one of 

 his charges. 



Mr. Swainson, in his second letter, leaves all these my answers perfectly 

 untouched : he resorts in it merely to the stale device of a baffled contro- 

 versialist, that of doggedly reiterating the assertions which had been again 

 and again refuted; and, flying off to subjects utterly unimportant in them- 

 selves, and equally irrelevant to the points at issue, exhibits, by his mis- 

 representations, misquotations, and the contradictions contained in his 

 statements and arguments, but the intemperate ebullitions of disappointed 

 malice. To these new points of discussion I shall address myself one by 

 one in your ensuing Number. 



There is also a letter in your last Number (Vol. IV. p. 487.) professing 

 to be the production of M. Lesson. As that gentleman seems not to under- 

 stand the nature of the subject at issue between himself and me, but to 

 view it through the medium of others, certainly not much more friendly 

 to him than to myself, I shall take an early opportunity of representing 

 to him and to your readers the real state of the question. 



I remain, dear Sir faithfully yours, 



N. A. Vigors. 

 Regent's Park, Dec. 10. 1831.
