ANNOUNCEMENT. 



The Colorado College Scieiitific Society was organized on the 

 22nd of January, 1890. The five regular meetings, thus far 

 held, have shown on the part Of its members a gratifying zeal 

 for the welfare of the Society, and earnest interest in science. 

 Though only five months old, the Society ventures to send forth 

 a sm'all volume containing six of the papers read at its meet- 

 ings; and requests of associations of like nature the favor of an 

 exchange of publications, hoping that subsequent volumes will, 

 more fully than the present pamphlet, substantiate a claim to 

 attention. 



Among the papers read before the Society there were others 

 not inferior to those included in this publication, in point of 

 originality or of interest of topic or treatment. For one reason 

 or another, it has not been practicable to present them here. 

 The following is a complete list of the papers and " reports " 

 read before the Society:
