 oak plantations. I fear the i^aub extract, from the fruit of 

 embryopteris ghitinifera, which I sent you some time since 

 for the trial of the tanners, may not have answered so well as 

 I expected, otVierwise that you would have applied for more 

 of it. 



1 take the present opportunity to request you will correct Hurrs, the

23d- volume of the Society's Transactions, page 408, where 



I said hurra was the fruit of terminalia citrhta ; I now find it 



IS the fruit of terminnlia chebu/a.—Si^e Coromandel plants, 



2, No. 1J)7, and of Wildenouw's edition of the Species 



Plautarum, 4, 969. 1 now send to yon a drawing and 

 description of the tree, and of the myrobalans in their 

 various staores, both fresh from the tree and dried as men- 

 tioned by Dr. Fleming. The small parcel within the other 

 contains some of the drug purchased in the bazar, viz. four 

 pounds weight, for which "I paid one shilling. The remain- 

 der are fresh gathered from two trees in this garden, and. 

 hastily dried in the sun; they are rather advanced, and may 

 answer to the fourth, fifth, and sixth sorts of the drawing; 

 and among those of the bazar will be found the three first.

 difficult to judge how long we may be conveniently sup- 

 plied with Peruvian bark ; and it is therefore very proper, 

 that this valuable substitute should be brought into general 

 use as soon as possible, and if it is likely to meet with exten- 

 sive demand^ 1 will contrive that some of it be sent^ home 

 for sale. #'

 boinensis, 7» p- 27j t. 15 : it is a thin bark, and may pro- 

 bably be as good or better than simarouba. In the same 

 bundle is another parcel, which is the conessi bark o{ oar Conetsi hark. 

 Materia Medica ; it has an austere bitter taste, and is re- 

 commended in dysenteries, diarrhoeas, &c., as an astrin- 

 gent.
