necessity. 
During six months, the winds in that 
sea blow invariably to the north or 
~north-north-west; and during the other 
six months, as unchangeably to the south 
or south-south-east, 
Beyond the straits of Babelmandel, 
the winds for the first half of the year 
never shift from the south or south-west, 
nor in the last half from the north 
or north-east, so that the whole pas- 
sage may be performed sailing before 
the wind. Moreover, the harbour of 
Mocha is most conveniently situated to 
answer the purpose of a port to refresh 
at, or to wait the most favorable period 
for prosecuting the voyage. -

the advantages which would arise both 
to Europe and India, from the establish- 
ment of any people in Egypt except the 
Mamelukes, Turks, and Arabs, since 
they must be evident to every person not 
blinded by selfishness and prejudice.

account of the various articles of com-

nishes the. best: thirty Turkish ships 
bring annually from Gedda to Suez; 
about 30,000 bags, the average value 
being about 30/. each, or 900,000/. 
ia the whole. This coffee is des- 
tined for the supply of Egypt, Syria, 
Constantinople, and all European Tur- 
key. A considerable quantity of it is 
likewise consumed in Bagdad and Mosul, 
being brought by sea to Bassora, and 
thence dispersed over the above-menti- 
oned places, and all the inner parts of 
Asia Minor, Marseilles received from 
Alexandria a quantity valued at from 
100,000/. to 150,0Q%’. every year.

SIR, 
N reply to your querist, on the sub- 
ject of the gloss on drawings in In- 
dian ink, I have to inform him, that too 
much gum in the composition of the ink 
employed in the drawings in question, is 
the cause of the offensive gloss; and 
which must arise in different degrees 
from what is called Indian Ink, accord- 
ing to the caprice, carelessness, or igno- 
rance, of the manufacturer, who isto be 
found, I believe, much oftener in Eng- 
Gloss on Drawings.—Canards Tigrés. 549 
land thanin India. The evil is, I fear, 
irremediable, im drawings made with 
such ink, without the risk of defacing 
their surfaces. But it may be avoided, 
by the artist composing his own ink, 
which ray be done by an union of ivory 
or lamp black, with a small portion, of 
Prussian blue or indigo, for a blue black; 
and the same blacks united with raw or 
burnt umber, bister, Vandyke, or any 
other brown instead of the blue, for a’ 
brown black. These should be bound 
together by mixing them in weak gum- 
water (or perhaps malt-wort would an- 
swer the purpose better), having first 
levigated them very fine in common 
water ona marble slab. When dried to 
the consistence of a paste, the glutinous 
matter should be then (and not till then) 
well mixed with them; the proper 
strength of which may be readily known 
by afew experiments, and that will be 
found sufticiently strong which binds the 
composition enough to prevent rubbing 
off by the touch, Indian ink drawings 
should be handled as little as possible ; 
for the slightest rubbing produces a cer- 
_tain degree of gloss, and frequent repe- 
titions of it make the gloss more apparent 
and-decided. I hope these bints may 
prove useful to youmcorrespondent.

BERS 
HE inquiry your correspondent, 
Mr. James Jennings, makes (in 
your valuable miscellany for last 
month) relative to the term “ Cunards 
tigrés,” would have been much facilitated 
had he mentioned the part of the world 
in which such a species of duck is stated 
to be found. 
I have searched the ‘ Dictionnaire 
raisonné universel d’ Histoire naturel, par 
M. Valmont-Bomare,” but without suc- 
cess, I should conceive that ‘* Canard 
tigré”’ may be rendered “ Liger-striped 
duck;” if so, probably the * Anas Jama- 
icensis,”. or ‘Jamaica shoveler,” is the 
species intended. This bird is described 
as follows, in Dr. Rees’s Cyclope- 
dia, (vol. 12, parti.) article ‘ Anas.” 
“ Length, sixteen inches ; the bill broad, 
bluish, orange at the sides; legs orange ; 
back-brown; sprinkled with yellowish 
sagittated dots, and tail cuneated, tis 
a native of Jamaica, where it first ap- 
pears in October or November, and 
retires northward in March.” 
Iam led to this conclusion, from the
