PROOFS. 



The advantages Nos. 1,2, 3, 4, and 5 are too self-evident 

 to be disputed, and are therefore necessarily admitted. 



Under No. 6 it is stated that in my edition " All the foreign 

 measures are converted into corresponding English terms, which 

 they are not in any other" This passage has been construed 

 as if my translator had asserted that none of the measures 

 were converted in Mrs. Sabine's edition, a meaning neither 

 intended, nor, as it appears to me, implied. 



As, however, Messrs Longman and Mr. Murray "feel 

 called upon to state that Mrs. Sabine's translation does contain 

 both the English and the Foreign measures," — and this in the 

 positive degree, without any qualification — I feel called upon 

 to subjoin an official letter to me on the subject, she wing- 

 that it does not contain them, that is to say, not all. 



Dear Sir, London, Feb. 25, 1849. 



Every calculation, without a single exception, m your edition of 

 Cosmos has been made by myself. Your letter has, therefore, been 

 put into my hands, and I hasten to reply to it. 



It is true that in Mrs. Sabine's translation very frequently the num- 

 ber of French feet and the centigrade degrees (when they occur in the 

 text) have, appended to them, the corresponding English feet and 

 Fahrenheit degrees ; but even in the text this is by no means universal, 

 and in the notes we constantly meet with untranslated measures. I 

 refer you for your personal satisfaction to the following notes : — 

 Note 2. Toises and Metres some 20 times. 



„ 4, page 363. We read of " a large white ape with a black face 



as far north as 34° N. Lat." (We are not in 

 the habit in this country of measuring apes' 

 faces by degrees of latitude. ) 

 „ 5 „ 363. Innumerable unconverted toises. 

 „ 83 „ 389. French feet. 

 „ 124 „ 397. Several measures left unaltered. 

 „ 125 „ 399. One ditto. 

 „ 140 „ 407. AH in centesimal degrees. 

 „ 348 „ 449. French feet. 

 „ 360 „ 452. Ditto. 

 „ 381 „ 457. Millemetres unconverted. 

 ,, 383 „ 460. French lines. 

 I have not time to look over the text." and have probably omitted 

 many of the notes which might have been brought forward in evidence. 



On incidentally opening at pp. 306, 331, 220, and 222, 1 find unre- 

 duced foreign measures, but have not time to continue the search. I may 

 add that in several cases I found Sabine's reductions incorrect.
