give an impetus to the employment of talents and capital 
in our own country. Having the advantage of the protec- 
tion afforded by the duty, and a further guard against frauds 
by this law, American enterprise will soon rival older and 
more experienced chemists in the manufacture of necessary 
articles. American quinine has gained a just celebrity, and 
is extensively used by those who have long been familiar 
with the impositions of labels and other counterfeit repre- 
sentations of popular foreign chemicals, and has recently 
become an article of export.* 
An argument used with much pertinacity by the oppo- 
nents of this law on its introduction, and one which time 
alone could test, was, that the revenues of the government 
would be greatly injured by its restrictions. It has been 
my constant care to ascertain this important fact ; and I am 
most happy in the belief that, although it cannot be demon- 
strated by figures, (as no separate record has been kept in 
the various districts by which a comparison could be in- 
stituted.) yet proper inferences are deducible of its satisfac- 
tory action in this particular. The collector at New York 
acknowledging his want of record to answer the question , 
as will be seen by reference to his letter, says : " In regard 
to the complaint alleged, viz. the reduction of the receipts 
in the way of duties, if it were indeed true, it should not, 
in my opinion, have any effect in deciding the merits of the 
* I have on my table specimens of the quinine manufactured by 
Rosengarten & Denis, of 'Philadelphia, which fully equals the best 
French quinine in purity and strength. These gentlemen recently ex- 
ported a large quantity, and by reference to the London circular, of 
November 3d, we find it met a ready sale, as " the quality was fine 
and has been much admired." Messrs. Farr, Powers & Weightman. 
also of Philadelphia, make quinine of equal purity to any in the 
world. I have procured from their establishment a sample, which, on 
analysis, indicates great purity, and its use has fulfilled my highest 
expectations. These gentlemen also manufacture morphine equal to 
Pelletier.
