Sir, 

 Having felt much interested in a very learned essay of the 

 distinguished Italian Antiquary, Antonio Nibby, on the ma- 

 terials employed in the construction of the ancient edifices in 

 Rome, I had long cherished the idea of presenting you with 

 a translation of it, with some additions from my own observa- 

 tions Learning that a paper on the same subject had appear- 

 ed in the sixth number of the Edinburgh New Philosophi- 

 cal Journal, and being anxious to see what had already been 

 published in this line of inquiry, I procured that number of 

 the work, and what was my surprise to find that a Mr C. T. 

 Ramage, A. M. of Naples, comes forward with a mangled 

 translation of part of Signor Nibby's paper, without the smal- 

 lest allusion to the source whence he had derived the whole in- 

 formation of his performance ; nay, that it is all rendered, word 

 for word, from Italian into English, with very small attention to 

 the idioms of the two languages, and with three short interpo- 

 lated passages of his own, which serve to betray how unfit he 

 was to do anything but translate on such a subject, as I shall 

 endeavour to illustrate in the note below. * Feeling anxious 



• The work of Nibby is his " Trattato preliminare dei Materiali usati 

 negli Antichi edificj di Itoma" prefixed to his erudite work on the Forum 

 and Via Sacra. The first paragraph is of course varied in Mr C. T. lla- 

 mage's translation, though exceedingly slightly ; but when the author ar- 

 rives " in medias res" the version becomes perfectly verbal, as the com- 

 mencement of the second paragraph (merely as a specimen of the whole) 

 will sufficiently prove to any one acquainted with the two languages. " La
