324 UNIO ITINERARIA. 
friends of Botany will consider these terms very moderate, 
when they take into view the distance of the country and the 
very heavy charges upon freight. The specimens are generally 
complete and very fresh; the fruits being added to a good 
nuniber of them. 
To give an idea of the rarity of the species which are in 
the two collections, we here cite the names of some :— 
Iris Sibirica, Stev.—ZEgilops squarrosa, L. (erroneously 
marked as Æ. cylindrica, Host.)— Triticum orientale, M.B. 
— Minuarta montana, L.—Scabiosa micrantha, Dest.—Ptero- 
cephalus plumosus, Coult.—Galium Ruthenicum, Willd.— 
G. tenuissimum, M.B.—Lithospermum tenuiflorum, L.— 
Lysimachia dubia, Ait.—Phyteuma campanuloides, M.B.— 
Cynanchum | acutum, L.—Astrantia Caucasica, M.B.— Ane- 
thum cymbocarpum, D.C.—Scandix australis, L.—Sium lanci- 
folium, M.B.—Ornithogalum chloranthum, M.B.—Cucubalus 
fimbriatus, M.B.—Silene saxatilis, M.B.—S. spergulefolia, 
M.B.—Pimpinella aromatica, M.B.—Queria Hispanica, L.— 
Allium albidum, Fisch.—A. rubellum, M.B.—Cerastium fri- 
gidum, M.B.—Pyrus eleagnifolia, Pall.—Capparis herbacea, 
Willd.— Delphinium divaricatum, &c. 
We embrace this opportunity of announcing a new 
expedition, and request the co-operation of all those who 
are friendly to natural science. Two naturalists, M. G. 
Schimper, already known to the members of this Society by 
his journey to Algiers, and M. Wiest, a doctor of medicine 
and botanist from Wurtemberg; will start during next 
month for Egypt, whence they will proceed towards the 
close of the year to Arabia, to explore principally the shores 
of the Red Sea and the chain of Mount Sinai. The convent 
of St. Catherine, where they will receive hospitality, will 
afford a favourable place for keeping their collections in 
safety, and thence they can be forwarded to Europe by way 
of Suez and Alexandria. 
The wishes that M. De Candolle had expressed in a letter, 
directed our views long ago to Arabia, and the particulars 
which M. Gay of Paris has kindly communicated respecting
