JANUARY, 1902. 
PROCEEDINGS. 
7 
The report of the January meeting was read by the secretary 
and reports of two section meetings by Chas. E. Brown. At one 
of these — a nieeting of the Archeology Section on the 2ist— it had 
been proposed to extend the membership of the section so as to 
include archeologists from all parts of Wisconsin, and thus give 
the section the character of a state organization. 
As a preliminary step in this direction Chas. E. Monroe gave 
notice that at the next meeting he would propose a change in the 
by-laws of the society so that hereafter the fee of non-resident 
members should be one dollar a year. 
Mr. A. W. Slocum then read an instructive and interesting 
paper entitled, "The Development of Life Upon the Earth as Re- 
vealed by Paleontology." 
After a brief historical account of the growth of the science, 
the different forms of fossils were mentioned and described, as 
well as illustrated by specimens and plaster of Paris models. 
The geological eras were then considered in their order and 
at this point Mr. Slocum displayed a set of charts prepared by 
himself to illustrate the development of each of the classes of the 
animal and the vegetable kingdoms during geologic time. Each 
class was then taken up separately and its development clearly 
described, numerous specimens from the Public Museum collec- 
tion of fossils being employed to illustrate the subject. 
At this meeting Mr. Otto Grigrutsch was elected an ordinary 
member of the society. 
Thursday, March 28, 1901. 
President Teller presided over this meeting, at which twenty- 
eight persons were present. The minutes of the last meeting were 
read by the Secretary and Mr. C. E. Brown reported on two sec- 
tion meetings of much interest that had been held earlier in the 
month. 
The lecture of the evening was to have been one on paleon- 
tology by Dr. Stuart Weller of Chicago, but the day previous 
word had been received from him that he would not be able to be 
present. 
Three members of our society had therefore hastily prepared 
papers for the evening, which, if somewhat incomplete, were yet 
interesting on account of the variety of subjects treated. 
The first paper by C. E. Brown was on the "Geographical Dis- 
tribution of the Milwaukee Butterfly, Anosia pie ^ip pus.'* The de- 
velopment and habits of this commonest of oui lepidoptera were 
described and its range on the American continent shown to be 
from the shores of Alaska and Hudson Bay to the northern boun- 
daries of Patagonia.
