60 Information respecting Botanical Travellers. 



pical districts collect at least 2000 species (Mr. Ecklon collected 

 thrice that number in the three years he spent in South Africa), it 

 will be seen that a treble subscription of 60 florins will not meet 

 the value of an entire collection made during the two or three years' 

 absence of M. Schimper. But to those who subscribe 120 florins we 

 will ensure to them the future collections at the same rate of sub- 

 scription. 



We think that the subscribers may rest assured, that whereas the 

 century of species will cost them 15 florins (33 francs), those indi- 

 viduals who may apply afterwards will have to pay 20 florins (42 

 francs). Up to the present time we admit of contributors coming 

 forward to the smaller amount of 50 — 60 florins : these, however, 

 can only claim three or four centuries at the subscription price. We 

 again venture to express our hope that such botanical friends as 

 possess the means, particularly public cabinets of natural history 

 and those individuals who have hitherto been members of the Unio, 

 will not forsake us in this important undertaking; and especially that 

 they will consider this journey as a national enterprise, which for 

 the honour alike of country and of science they will do their best 

 to promote. 



As our traveller also collects zoological objects, especially bird- 

 skins, fish, and shells, the amateurs of these respective departments 

 of natural history may secure a proportion of them, according to 

 their subscriptions, observing, however, that the contributions to- 

 wards this journey have some analogy to stock, whose value rises 

 and falls according to circumstances. The greater, however, be the 

 assistance afforded to the traveller, to enable him to prolong his 

 stay and in safety to prosecute his researches, the richer may the 

 proceeds be expected to prove. 



To those members who take an interest in the productions of the 

 Georgian Caucasus, we beg to intimate that fresh packets have just 

 arrived from M. Hohenacker, containing 200 species, most of which 

 had not been previously sent, and of the rest only individual speci- 

 mens. Particulars are mentioned in the Appendix. 



Of the North American plants of the deceased Dr. Frank, there 

 remain collections of 100 and of 200 specimens. These will be sold 

 at 12 florins and 24 florins, after the period during which the sub- 

 scription of 1 1 florins was admissible shall have closed. 



Lastly, we are enabled to offer to the respected Members of the 

 Unio and to other botanists, dried plants from New Holland, which 

 the Royal Botanic Society of Ratisbon has transmitted to us for va- 

 luation and sale. They were collected by Dr. Lhotsky, at Sydney 

 and Port Jackson, and are described by us and consigned to us on
