Arslonga, vita brevis. 



Especialh^ does life and its associations seem short to the 

 man in the lecture room. It is his privilge to continually make 

 new and most pleasant acquaintances with open and unbiased 

 3'Oung minds and hearts, but it is also his fate to be compelled to 

 part with them, as be feels, altogether too soon, often never to 

 meet them again. 



To each and every member of my former classes in Meteor- 

 ology, and especially to the members of the Weather Club. I ex- 

 tend my thanks, and desire to present a copy of this paper.
