Sinx'e the first publication of the annexed Rejoinder, in 

 the concluding paragraph of which I announced my inten- 

 tion of publishing the other works of Humboldt, uniform 

 with his " Cosmos," an advertisement has been issued on the 

 other side, threatening to anticipate me with one of them, viz. 

 " Ansickten der Natur" a little work first published in 1808, 

 again in 1826, and translated into French in 1828, under the 

 title of "Tableaux de la Nature," and. which, till now, nobody 

 seems to have thought worth publishing in England. As 

 Baron Humboldt had himself recommended this work to mv 

 attention, and at the same time informed me that he was 

 engaged in a careful revision of it, I determined to make it 

 one of the earliest of the series, and was merely waiting, in 

 compliance with his suggestion, till the new edition was 

 published. 



I shall make no objection to the party opposition which 

 is arising to my cheap editions, but call upon the Public to 

 examine the grounds of it, and to consider well the policy of 

 encouraging what may end, according to my view of the 

 question, to their own disadvantage. At any rate, it is 

 hoped they will await the publication of my edition, before 

 they determine which is best worth their patronage. Mine 

 will probably not be the first in the field, as. though I am 

 no laggard, I think it of more importance to publish with 

 care, than with speed.
