The Bulletins (formerly sold, but by authority of joint resolution approved May 16,

issued is large. They have therefore been classified into the following series: A, 
Economic geology; B, Descriptive geology; C, Systematic geology and paleontology; 
D, Petrography and mineralogy; E, Chemistry and physics; F, Geography; G, Mis- 
cellaneous. This bulletin is the fifteenth in Series A, the complete list of which
