ACCOUNT 
having gone twenty-one miles. We 
were here at once {urprifed and ter- 
rified by a fight furcly one of the 
moft magnificentin the world. In 
that vaft expanfe of defert, from W. 
and to N. W. of us, we faw a num-. 
ber of prodigious pillars of fand at 
different diftances, at times moving 
with great celerity, at others falk- 
ing on with a majeftic flownefs: at 
intervals we thought they were com- 
ing in a very few minutes to over- 
whelm us; and finall quantities of 
fand did actually more than once 
reach us. -Again they would retreat 
fo as to be aimoft out of fight, their 
tops reaching to the very clouds. 
“There the tops often feparated from 
the bodies ; and thefe, once disjoin- 
ed, difpefied in the air, and did not 
appear more. Sometimes they were 
broken near the middle, as if ftruck 
with a large cannon-fhot. About 
noon they began to advance with 
wind being very ftrong at north. 
Eleven of them ranged alongfide of 
us about the diftance of three miles, 
The greateit diameter of the largeit 
appeared to me at that diffance as if 
it would meaiure ten feet. ‘They 
‘ retired from us with a wind at S:E. 
leaving an impreffion upon my mind 
to which I can give no name, though 
furely one ingredient in it was fear, 
_ with a confiderable degree of won- 
' der and aftonifhment. It was in vain 
to think of flying; the fwifteft horfe, 
or fafteit failing fhip, could be of 
no ufe to carry us out of this dan- 
ger, and the full periuafion of this 
‘Tivetted me as if to the ipot where 
I ftood, and let the camels gain on 
me fo much in my {tate of lamenefs, 
that it was with fome difficulty 1 
could overtake thém.”’ | 
Mr. Bruce has added a fifth vo- 
ume, in the form of an appendix,

OF BOOKS. 14977, 
with a view of preferving the fub- 
ject of natural hiftory diltingt from 
the other objects of his travels. He 
was apprehenfive that by prefenting 
the two fubjects promifcuoufly, he 
might incommode and difguit both 
{fpecies of readers. 
The firit portion of this part of 
the work treats of trees, fhrubs, or 
plants; and in the felecting of them, 
our author obferves, that he has 
preferred thofe which, having once 
been confidered as {ubje€ts of con- 
fequence by the ancients, and treat- 
ed largely of by them, are ‘now 
come, irom want-of the advantage 
of drawing, lapfe of time, change of 
climate, alteration of manness, or 
accident befallen the inhabitants of 
a country, to: be of doubtful exift- 
ence and uncertain defcription. 
After having beflowed his firft 
confideration upon thofe that make 
a principal figure im ancient hiftory, 
which ‘are either not at all or im- 
periectly known now, his next at- 
tention has been given to thofe 
which have their ules in manufac- 
tures, medicine, or are ufed as food 
in the countries he is defcribing. 
The next fubje@ treated of are the 
plants, or the varieties of plants un- 
known, whether in genus or ipe- 
cies, 
Amongft thefe he gives the fol- 
Jowing account of a plant calied by 
the Abyflinians Wougincos.

cially the fides of the valleys ia the
