MANNA-CINCHONABALSAM OF COPAIBA. 



289 



BALSAM OF COPAIBA. The specimen sent from Trinidad is 

 interesting as being entirely produced by one species, namely, 

 Copaifera officinalis, Jacq., a tree abundant on the south coast of 

 the island. Balsam of Copaiba is not at present, I believe, an 

 article of export from Trinidad. 



SEEDS OF SCAPHIUM ; BOA-TAM-TAIJANG. In a recent number 

 of the Pharmaceutical Journal, l I described and figured under 



1 July, 1861, p. 6. 



Alliagi 



Manna. 



which when fully developed, escapes by boring a passage through isea. 

 the top of the cell to the outer air. 



The Lerp Manna has an odour resembling manna of the ash, Ler P 

 a similar colour and the same clammy feeling to the touch ; it 

 has a saccharine taste, but does not dissolve in the mouth. It is 

 not wholly soluble in cold water or in cold alcohol ; boiled in 

 water, it breaks down so as to form a turbid mucilaginous liquid, 

 which is coloured intensely blue upon the addition of iodine. 

 Like the Australian manna previously noticed, the Lerp manna 

 has not at present any useful application. 



4. Alliagi Manna has been sent to the Exhibition from India. 

 It is a saccharine substance in small, loose, dry grains of a pale 

 brown colour, mixed with both leaves and pods of Al/iagi 

 (? Maurorum, Tourn.). It therefore differs in appearance from 

 the Syrian alhagi-manna, sent by Dr. Gaillardot, of Saida, to M. 

 Leon Soubeiran, which the latter describes as compressed into 

 loaves or cakes. 



CINCHONA BARK. Neither Peru, Bolivia, Ecuador, nor New 

 Granada have contributed any series of the Cinchona barks 

 which are produced in their forests. There is, however, a fine 

 general collection exhibited by Messrs. Howard and Sons, of 

 London, and illustrated by drawings of the plant as well as by 

 healthy living specimens of Cinchona succirulra, Pav., C. micran- 

 tha, E. et P., C. Uritusinga, Pav., C. nitida, E. et P., and C. peru- 

 viana, Howard. Among the productions of the Dutch colonies 

 are specimens of genuine Calisaya bark grown in Java, also of 

 the bark of C. Pahudiana, Howard, a species of very little 

 medicinal value.
