MONOPOLY OF YELLOW OR CALISAYA BARK. 
45 
Of the pale bark, Cinchona flava, [Carthagena] 1 oz. furnished 
6-35 grs. of colored alkaloid, or 1*32 per cent.; but it differs very re- 
markably from the C. regia, not only by its external characters, but 
also from its containing no quinine ; the alkaloid in this kind appears 
to consists for the greater part of cinchotine. From the large amount 
of alkaloid contained in it, it is probable that the C. flava, though 
not to be compared with C. regia, should be counted among the 
most active of the barks. 
The spurious barks, both the Surinamensis and the Brasiliensis , 
are easily distinguished from the genuine by their external charac- 
ters as well as by the fact that they furnish with acidulated water 
reddish-brown or brownish red, and not pale yellow infusions, from 
which no alkaloid is precipitated by ammonia or carbonate of soda; 
they consequently possess no greater pharmacological value than 
the barks of our willows, ash and horse-chestnut. — London Chem.

MONOPOLY OF YELLOW OR CALISAYA BARK. 
[Through the kindness of some friends we have been favored with a copy 
of the Report of the Secretary of the Treasury of Bolivia to the National Bank 
of Bark, and also with a copy of the Decree of the Government of Bolivia, 
prohibiting bark cutting in the Bolivian forests for three years. The results 
of these monopolies, by raising the price of Calisaya bark, has been to force 
the manufacturers of quinine to resort to the inferior but cheaper quinine- 
yielding barks of Carabeya, Bolivia, and New Grenada. — Ed. Lon. Pharm.

Report of the Secretary of the Treasury of Bolivia to the National Con- 
gress, regarding the National Bank of Bark. 
It is highly satisfactory to me to announce to Congress the esta- 
blishment of the National Bank of Bark, which has been accom- 
plished in the city of La Paz, by means of the authentic contract 
entered into between the Government and Messrs. Aramayo 
Brothers, under the conditions and bases of their proposal and 
those contained in the supreme resolutions of the 17th and 26th 
January, 1850. The constant desire of the nation expressed in 
the solemn legislative acts since the year 1839, had been for an
