124 BOTANICAL INFORMATION. 
formed by a prominent mass of trap, and seen from the sea is like a 
cone, and is called Innosuoset (a watch-tower). This point is from 
3700 feet to 3800 feet above the sea. Of the plants gathered in this 
excursion the last, Salix glauca, was at the height of 3300 feet, and 
here at Innosuoset was found, in addition to the above-named plants, 
the Draba alpina. : 
Notes upon the Drugs observed at Aden, Arabia; by JAMES VAUGHAN, 
Esa., Member of the Royal College of Surgeons of England, Assis- 
tant Surgeon to the Bengal Army, Civil and Port Surgeon at Aden, 
Arabia. 
Such is the title of a valuable article communicated by Daniel Han- 
bury, Esq., to a late number of the ‘ Pharmaceutical Journal,’ 1853. It 
is full of important information, collected by a gentleman every way 
qualified for such an undertaking, during an official residence at Aden. 
* With some of these vegetable productions," Mr. Vaughan observes, 
* the commercial and scientifie world are already acquainted, with others 
they are less familiar, and of a few it may be presumed that they know 
scarcely anything. With regard to science and especially medicine, it is 
much to be regretted that some eminent Botanist does not turn his at- 
tention to this part of the world, where nature has been so lavish in her 
precious gifts, and where a wide field of research is open to him, from 
which he might make many important and original additions to the 
present stock of medical knowledge, and thereby establish a high claim 
to the esteem and gratitude of his profession in particular, and of the 
scientific part of the community generally. -Scarcely anything is known 
at present of Eastern Africa beyond the sea-board, and the same re- 
mark applies to Southern Arabia. With regard to the latter country 
in particular, famous even in the early ages of the world for its valuable 
vegetable produce, it appears almost unaccountable that this country 
` should be well-nigh as little known to us as it was to the learned in the 
days of the ancient Greeks and Romans." 
We must refer to the memoir itself for the more full particulars of 
the Drugs described in the **Notes," and must content ourselves with 
mentioning those which especially demand further inquiry from the man 
of science, to determine the particular plants which yield them.
