Mr. Nipher made additional remarks as follows : 



It is with mingled feelings of pain and pleasure that we assemble here 

 to-night. The occasion reminds us of one who formerly bore his part with 

 us, and who labored long and earnestly to promote the interests of science 

 in our midst. But with our sorrow at the loss of so noble a companion, 

 comes also the feeling that the cause for which he labored is not lost. The 

 workmen perish, but the work goes on. The cause of science is now so 

 firmly fixed in the minds and hearts of its promoters, the methods and re- 

 sults of scientific work have come to form so essential apart of our modern 

 intellectual life, and the material comforts and prosperity of society are 

 now seen to be so directly involved in the progrefs of scientific discovery,
