NGAI CAMPHOR. JJ93 



of Pareira Brava imported into New York in 1871 consisted in 1873. 

 large part of a drug entirely different from any previously seen, 

 and that he at first supposed it an adulteration; but that 

 subsequent examination had shown him that the drug in 

 question agreed well with the older descriptions of Pareira Brava, 

 and especially with Pomet's figure, so that he was convinced 

 it was true Pareira Root. From Dr. Squibb's description I feel 

 sure that the drug before him was the same as that to which I 

 have called attention in the present paper. 



There can be no doubt that it would become plentiful if the 

 demand should arise, and that it would advantageously replace 

 the worthless kind now found in the drug trade. [^V. Repert.

ON A PECULIAE CAMPHOE FEOM CHINA. 



(Neuer Campher aus China, von Blumea balsamifera,) 

 (BL grand-is, B.C.) 



ALTHOUGH the Chinese make large use of ordinary camphor, is/4. 

 that is to say, of the camphor produced in Japan and Formosa 

 by Cinnamomum camphora, F. Nees et Eberm., it is well known 

 that they attach a much higher value to the camphor obtained 

 in Sumatra and Borneo from the stem of Dryobalanops aromatica, 

 Gartn. 



But there is a third kind of camphor standing intermediate 

 in value between these two, and much less known, to which I 

 desire to draw attention. 



Eondot, in his work on Chinese commerce, 1 published in 1848, 

 after speaking of the camphor of China, and before describing 

 Malayan or Dryobalanops camphor, has a remark in reference 

 to the drug under notice, to the following effect : 



There exists also another sort of camphor, extremely white, 

 which is extracted from the leaves of a plant known in China 

 under the name of Ngai, a variety of Artemisia. It occurs in 

 crystals, which are very pure, clear, brittle, with a shining 

 fracture ; it is much esteemed in China.
