64 NOTICES OF SOME RARE KINDS OF RHUBARB. 
I have recently met with a third sort, corresponding with 
neither of the kinds just alluded to, and which, on account 
of its resemblance to the English stick variety, I shall call 
Canton stick rhubarb. It is only recently that this sort 
has appeared in the market. Five cases of it were import- 
ed from Canton, and were sold during the last year by 
public sale, at eight pence per pound. 
All the pieces but one of my sample, are cylindrical, about 
two inches long, from half to three quarters of an inch in 
diameter, and weigh each on the average about 100 grains. 
The piece to which I have referred as forming the excep- 
tion, is shaped like a flattened cylinder, cut obliquely at 
one end ; its greatest length is about two and a half inches, 
its greatest breadth two inches and a quarter, while its 
depth is about one inch, and its weight is about two ounces. 
Mr. Faber, from whom I received it, tells me, that on the 
examination of a quantity of Canton stick rhubarb, he found 
several such pieces. 
Most of the pieces are decorticated. These resemble 
English stick rhubarb in their texture and colour, except 
that they are, perhaps, somewhat paler, the taste is bitter, 
a r d somewhat astringent, but considerably less so than that 
of good, half-trimmed, Canton rhubarb. By chewing it, 
little or no grittiness is perceptible. 
This kind of rhubarb is probably obtained from the root 
branches of the plant which yields the usual Canton rhu- 
barb. 
2. Bucharian Rhubarb. 
By most writers the term Bucharian rhubarb is employed 
synonymously with that of Russian rhubarb. But there 
has long been known in Russian commerce a rhubarb called 
Bucharian, which is not under the control of the crown, 
and which, on account of its cheapness, is used in veterina- 
ry medicine. Grassmann, an apothecary at St. Petersburgh? 
considers it to be the rhubarb which, according to Pallas, 
is obtained from Rheum undulatum, and which, in the
