Notes on the Mineralogy of Missouri. 

 By Alexander V. Leonhard. 

 This article contains : 



I. A descriptive catalogue of the mineral species of Mis- 

 souri. 

 II. A list of the important localities of minerals in Missouri. 



It forms the beginning of a series of publications on the mineral- 

 ogy of Missouri, which I am preparing at present. 



I may remark that all the species, enumerated in the catalogue, 

 are nicely represented in the "Collection of Missouri Minerals" 

 which forms a part of the mineral collections of the Mining De- 

 partment of Washington University.
