THE 



CALCUTTA JOURNAL 



OF 



NATURAL HISTORY. 



On East Indian Isinglass, its introduction to, and manufac- 

 ture for, the European Market, By the Editor. 



Having called attention to the subject in the March 

 Number of the Journal of the Asiatic Society for 1839, 

 p. 203, and again in the Researches of the Asiatic Society, 

 for October of the same year, it was our intention to re- 

 main silent regarding Bengal Isinglass, with the view of 

 allowing the article to work its own way in the English 

 market. 



But the appearance by the January mail of the proof 

 sheets of a pamphlet by Dr. Royle on this subject, ren- 

 ders a few observations necessary, in order that the in- 

 formation before the Government may be as complete as 

 the results which have been ascertained are capable of 

 making it.* 



* Dr. Royle's valuable Report on this subject has been reprinted 

 in full in our last number, together with additional notes of our own.
