which, on account of peculiar circumstances, this former 
expedition was attended. They will obtain gratis, a pro- 
portional share of the collections which our travellers may 
make on their road, and especially in Egypt, where they 
are to pass some months. ‘The extraordinary subsidies, to 
which we have alluded, and which are advanced to the 
travellers, enable us to make this arrangement. Of course 
the subscribers to the new expedition will not suffer by this 
engagement: the terms of the contract with our travelling 
naturalists being such as to permit a guarantee that the 
Arabian. plants shall not amount to a higher relative price 
than those Georgian collections spoken of above. 
We request all such as may desire to share in the fruits of

expectation, the number of shares taken for the Arabian 
journey be too few, the sums already paid will be returned, 
and the travellers will visit some suitable country with such 
resources as they may have; so that the Travelling Society 
will be free from any engagement with the shareholders. 
`- We would further point out that the object of this journey 
extends not to dried plants alone, but to seeds and bulbs :— 
likewise to zoological productions, namely insects, shells and 
fishes, for which we will receive separate subscriptions. On 
particular order, we can furnish Mollusca preserved in spirits 
of wine, reptiles, birds, skins and skulls of Mammiferz, &c. 
Dr. Wiest, taking by preference the botanical department, 
M. G. Schimper will particularly devote his attention to 
zoology, giving, however, all such mutual aid as may advance 
the great ends of the journey. They will likewise observe 
whatever may regard medicine, geography, ethnography, 
with a view to publish at some future time the result of their
