EGYPT, AND SYRIA. 271 
Arabs, and by fome efteerned efficacious as a remedy for cer- 
tain difeafes. It feems a flight diuretic. The wood is hard, 
and of a yellowifh colour ; it grows in great abundance, and is 
very thorny. This, together with the Nebbek, chiefly furnifli, 
thorns for the fences. 
6. Enneb^ a fmall tree, to the fruit of which they have given 
the name of grapes. It bears leaves of light green hue, and the 
fruit, which is of a purple colour, is attached, not in bunches, 
but fingly to the fmaller branches, and interfperfed among the 
leaves. The internal flru£ture of the fruit is not very unlike 
the grape, which it alfo refembles in fize. But the pulp is of a 
red hue, and the tafl:e is fl:rongly afliringent. 
7. Shaw, Ar. a flirub about the fize of the Arbutus, having, 
like it, a leaf of flirong texture, of oval form, pale green, wider 
at the lower, and narrower at the upper extremity than the 
arbutus. — The leaf has the pungency and very much the tafte 
of muftard. This flirub I faw chiefly in Wadi Shaw, a place 
we pafl^ed in going and returning, between Sweini and Bir-el- 
malha. The natives cut off* the fmaller branches, which they 
ufe to rub their teeth, alleging that the acrid juice of this plant 
has the property of whitening them. 
From an exad correfpondence as to the place of its growth, 
viz, near the fait fprings, the camels not eating it, and fome 
other circumfl:ances, I take this to be the Rack of Bruce, 
vol. V. p. 44. though unable to recognize it in the figure there 
given.
