16 Memoir of William Maclure. 



List of the published works and memoirs of Mr. Maclure. 



The following list embraces the separate works (two in num- 

 ber) and miscellaneous papers written by Mr. Maclure during his 

 residence in the United States. It is not presumed that the list 

 is complete; for it is more than probable that he contributed 

 something to the periodical journals of England, France, Spain, 

 and perhaps of Mexico, while resident in those countries. 



A reference to the following essays will show how exclusively 

 Mr. Maclure's mind was devoted to matters of fact, seldom in- 

 dulging in hypothesis, and never yielding himself, at least in his 

 writings, to purely imaginative reflections. 



1, Observations on the Geology of the United States of America, 



with some Remarks on the Nature and Fertility of Soils, &c. 

 Philadelphia, 1817. 8vo. This is a corrected reprint from the 

 Transactions of the American Philosophical Society. 



2. Opinions on Various Subjects, 2 vols. 8vo. This work is epis- 

 tolary, and was chiefly written in Mexico. It embraces re- 



flections on many subjects, but is mainly devoted to Political 

 Economy.
