Dear SIR, 29th July 1889. 
We beg to acknowledge the receipt of your letter of the 
25th July, enclosing copy of letter received from Mr. David Howard, 
giving analysis of two ires an of Loxa bark from Jamaica. 
On the market, now, bark analyzing as under would be worth, 
No. 1., 2:23 per e mc: ‘quinine, 21d., 24d. per Ib.; No. 2., 1°74 per 
cent. quinine, 2d. per lb. 
at any time only be too happy to give yos any information 
you may wish for about the market here for Cinchon 
We may say in passing that the fine old South vett H. O. Loxa 
quills mentioned in the letter by Mr. David Howard, are sold for the 
freudh market for making wine. This bark has a pec culiar flavour and 
bouquet, which are recognised and well known by the Parisians, which 
fragrant quality or bouquet are quite wanting in the Loxa bark when 
grown in India, Jamaica, or Java. Fine silvery H. O. South 
American Loxa would fetch upon this market 2s. 2d. to 2s. 64. per lb. 
Tharking you for the sight of these two analyses. 
We are, &e. 
(Signed) JENKIN & PHILLIPS.

DEAR SIR, July 31 
In Now return the two copies of reports on the Jaia bark, the 
perusal of which has much interested me. I am expecting some im- 
provement in the value of pamer later in the year. Those who have 
good bark should not, in my o nion, be in too much of a hurry to 
re : he market now is Ae wt more from a plethora of quinine 
than a redundancy o 
er this season, ending 30th September, I am told the exports from 
Ceylon will not again exceed n million pounds, and the fall will 
come gradually from that poiat according to supply and demand 
requirements. 
That there can arise any large increase in the value of bark during 
the next 18 months there are at present no grounds for supposing. 
Thanking you again for your courtesy, 
I am, &c., 
(Signed) Joun HAMILTON.
