The third collector. Dr. Lindheimer, a very assiduous botanist, 

 intends to devote a few years to the exploration of Texas ; and he 

 pledges himself to exclude from his sets all the common plants of 

 the south-western United States. 



These several collections will be assorted and distributed, and for 

 the most part ticketed, by Dr. Engelmann of St. Louis ; assisted, as 

 far as need be, by the authors of the ' Flora of North America,' who 

 promise to determine the plants, so far at least as they belong to fa- 

 milies published in that work ; and for the information of subscribers, 

 particular notices of the centuria offered for sale will probably ap- 

 pear in this Journal* as they come to hand. The number of sets being 

 limited, earlier subscribers will receive a preference. The three ex- 

 plorers are entirely independent of each other, and their collections 

 are to be separately subscribed for. 



The price of the Rocky Mountain collections of Geyer or of Lii- 

 ders is fixed at ten dollars (or two guineas) per hundred ; that of Dr. 

 Lindheimer's Texan collections at eight dollars (or 1/. 135. Qd. ster- 

 ling) per hundred — payable on delivery of the sets at St. Louis, Mis- 

 souri, by Dr. George Engelmann ; at New York by Wiley and Put- 

 nam, 161 Broadway, and Stationers' Hall Court, London ; and Prof. 

 A. Gray of Harvard University, Cambridge, Massachusetts, to either 

 of whom subscribers may address themselves (post paid) by mail. 

 The additional expense of transportation, doubtless trifling in amount, 

 will be charged upon the sets deliverable in London. 



The writer of this notice cheerfully states that the dried speci- 

 mens made by these botanists which have fallen under his observa- 

 tion are well selected, very complete, and finely prepared ; and he 

 cordially joins Dr. Engelmann in recommending the enterprise to the 

 patronage of botanists. 



For the purpose of obtaining some immediate pecuniary aid in the 

 prosecution of his present arduous undertaking, Mr. Geyer also oflfers 

 for sale (through the parties above mentioned) a selection from his 

 collections of the last year in Illinois and Missouri, consisting of 

 twenty sets of one hundred and fifty species of plants, which are 

 offered at six dollars per set. 



BIBLIOGRAPHICAL NOTICES. 



A Catalogue of British Fossils ; comprising all the genera and species 

 hitherto described, with references to their Geological Distribution and 

 to the Localities in which they have been found. By John Morris. 

 London, Van Voorst, 1843. 

 Naturalists of all classes will thank Mr. Morris for this most va- 

 luable volume, which, apparently a list of names, is in reality a sum- 

 ming-up of the state of our knowledge of British organic remains at 

 the present time, and being such, becomes the starting-point of future 

 research. It is no mere compilation, but the result of a critical ex- 

 amination of the characters, synonyms, descriptions, and published re- 

 presentations of all the species of animals and plants hitherto recorded 



* Silliman's American Journal, from which this notice has been taken.
