LI II. — Information respecting Zoological and Botanical 

 Travellers. 



Mr. Forbes and Mr. Thompson. — We have just seen Mr. Thomp- 

 son, who after visiting Constantinople, Smyrna, Athens, &c., has 

 returned from the Archipelago in consequence of the survey of Can- 

 dia being abandoned for the present year, or until the island becomes 

 more settled. We are happy to hear from him that he left Mr. Forbes 

 very well on the 10th of June at Port Nousa, in the island of Paros, 

 where he had then been for a month most successfully engaged in 

 his researches, especially in marine zoology. Mr. Forbes hopes to 

 be able to visit all the islands composing the Cyclades group during 

 the summer and autumn of the present year. 



We have received from him descriptions of some new and very re- 

 markable marine invertebrate animals, which we shall soon lay be- 

 fore our readers. 



Mr. Schomhurgk. — Recent letters from Mr. Schomburgk, dated 

 Demerara, 1 2th of April, mention his safe arrival at that place, and 

 that he was about to start on the following day to the westward to 

 the mouth of the Wayina, where would be his head-quarters for a 

 short time. All the party were well with the exception of Mr. Wal- 

 ton the draughtsman, who not finding himself strong enough for a 

 tropical climate was about to return to England. Mr. Schomburgk 

 expected to start for the interior of Guiana about the beginning of 

 August. 



Mr. W. S. MacLeay. — " As might be expected, the time spent on 

 the long voyage from England to Sydney was not lost ; the ocean 

 indeed is a rich domain to the philosopher. Mr. MacLeay mentions 

 having fallen in with the American Scientific Expedition, which left 

 the United States about eighteen months ago, in two corvettes and 

 four schooners. They had visited, when Mr. MacLeay met them, 

 the Cape de Verds, Brazil, Patagonia, Terra del Fuego, Chili, Peru, 

 and the South Sea Islands, and had made extensive collections in all 

 departments of natural history. The following are the scientific men 

 who compose the expedition, and their duties. Titian Peale for 

 mammalia and birds ; Dr. Pickering for insects, reptiles, and fishes ; 

 Mr. Coulter for moUusca, and Mr. Dana for Crustacea, pelagic ani- 

 mals, and geology ; Mr. Rich for botany ; two gardeners, and two 

 artists, complete the scientific corps. The expedition is creditable to 

 the United States, and we trust will prove highly important to the 

 advancement of science. Extensive collections were making in every 

 department of nature, which were forwarded to Philadelphia as op- 

 portunities offered. With regard to Mr. MacLeay himself, it is his 

 intention to remain four or five years in New South Wales, where 

 he thinks he will have occasion to publish some of the results of his 

 investigations without waiting for the remote prospect of his return 

 to England. He had made one journey to the Hunter river ; there
