OBSERVATIONS ON MUSK.

ence to the two different kinds of musk, so far as regards 
their chemical and mercantile relations. 
Taking, therefore, the most essential points of the preced- 
ing communication: — 1st, that the Russian musk is always 
sold in perfect bags, and exported in considerable quantities 
to China and to London; 2d, that from China to Russia no 
direct exportation of musk takes place; 3d, that the Chinese 
musk can only be obtained via London; 4th, that the Chi- 
nese musk bags never arrive unopened; 5th, that it appears 
most undoubtedly that the mass has been taken out and re- 
placed; 6th, that the external appearance of the bags proves 
sufficiently that they have undergone artificial treatment; 
7th, that frequently the secretion, apart from the bag, is im- 
ported from China, leading to the inference that a sufficient 
number of bags cannot be obtained, wherein to put the 
quantity increased by adulteration; taking all these reasons 
into consideration, we think the conclusion announced at 
the commencement cannot be avoided, viz. that the distinct- 
ly marked difference of the Chinese from the Russian musk, 
if not wholly, is at any rate chiefly, caused by the treatment 
which it undergoes in China, and therefore that Chinese 
musk is the natural product after it has been modified by 
artificial means. 
It is a fact worthy of remark, as showing the ignorance 
which exists in reference to the places whence products are 
obtained, that notwithstanding the fact that London receives 
the greater quantity of Russian musk, yet that in the 
Trades' List and Prices Current no mention is ever made 
of Siberian or Cabardinian musk. 
In reference to the quantity of musk on which duty has 
been paid, we find, on referring to the Customs' official 
documents, that in the year 1842, up to June 28th inclusive, 
the duty of 6d. per oz. was paid on 1643 oz., whilst during 
the same term in 1841 only 501 oz. were cleared. 
At the port of London alone, from June 1841 to June 
1842, duty was paid on 969 oz. — Lon. Chern. Gaz. Nov. 1,
