584 PROCEEDINGS OF THE ACADEMY OF [1895. 



of exhibition- room and cases ; indeed, at the present time, there is 

 even less room than heretofore, owing to the necessary division of the 

 main hall into a section devoted to entomological interests. Only 

 with occupancy of the new hall can proper relief be expected. 



The usual spring course of lectures has followed as a continua- 

 tion of the courses of past years, and it is gratifying to be able to 

 report that the attendance lias been steadily increasing year by year, 

 the enrolled students for the past season numbering 116. Emphasis 

 is again laid on that portion of the instruction which is associated 

 with field-work, when an opportunity is given to examine practically 

 much of that which is first illustrated in the class-room. In addi- 

 tion to the regular Saturday field-parties, the course included, for a 

 limited number, an examination in the month of August of the 

 Rocky Mountain region, when the practicability of so extended a 

 class- excursion was clearly demonstrated. The region studied com- 

 prised sections of Colorado, Wyoming, Utah and New Mexico, and 

 specifically the Pike's Peak district, gold mines of Cripple Creek, 

 " bad lands," Great Salt Lake, canons of the Price, Grand and 

 Arkansas Rivers, the volcanic masses of the San Juan, etc. 



As Professor of Geology, the undersigned would respectfully 

 recommend, the disposition of the geological materials of the 

 Academy, space in the new hall, and that enough of it be given 

 for that form of display which is now a part of the method of almost 

 every new museum. A geological exhibition means not merely a 

 display of rock specimens for themselves, but illustration of the 

 dynamics and economics of the science. Therefore, sections of rock- 

 strata, models of geological structure, well and coal borings, etc., 

 are eminently necessary for a proper or modern exhibition. 



Respectfully submitted, 



Angelo Heilprin, 

 Prof, of Invert Paleontology (to Dec, 1895), 



now Prof, of Geology.
