ume VI, on the temperature of Pine Lake. He contributed eight 
papers on the classification and habits of spiders, chiefly from the 
family Attidae. These appeared between 1885 and 1909, and aggre¬ 
gate about 800 pages with nearly 50 plates. 
The persons who subscribed to the fiftieth anniversary fund 
of about $1,200 and thus provided the medallion are the follow¬ 
ing: 
Dr. EL A. Birge, Madison, 
Hon. T. E. Brittingham, Madison, 
Hon. F. P. Hixon, La Crosse, 
Hon. A. J. Horlick, Racine, 
Dr. Charles K. Leith, Madison, 
Hon. Frank A. Logan, Chicago, 
Mrs. Charles W. Morris, Milwaukee, 
Dr. M. S. Slaughter, Madison, 
Dr. C. S. Slichter, Madison. 
The Academy recognizes a peculiar debt of gratitude to these 
donors who have enabled it to put forth so beautiful and signifi¬ 
cant a memorial. The reverse of the medallion displays in word 
and symbol the spirit of the Academy; the obverse commem¬ 
orates the first half century of its life and also preserves in en¬ 
during form the features of six citizens of the state and mem¬ 
bers of the Academy who during that time contributed so much 
to the advancement and development of knowledge. The Acad¬ 
emy has placed these donors on its list of life members in recog¬ 
nition of the service thus rendered. 
The Academy has also received gifts in the form of subscrip¬ 
tions for copies of the medallion, so that it might be more wisely 
distributed. About 50 members and friends of the Academy 
subscribed for one copy each and several subscribed for more 
than one, the additional copies being sent to institutions. 
Among the latter are to be named Miss Katharine Allen (5 
copies), Dr. E. B. Van Vleek (5 copies), and Dr. J. J. Davis 
(2 copies), all of Madison; and Mr. A. C. Clas (2 copies), of 
Milwaukee. In this connection also especial mention must be 
made of Hon. A. J. Horlick, of Bacine, who added largely to his 
original gift so that this memorial of Wisconsin history might 
become more generally known. These gifts have made it pos¬ 
sible for the Academy to place many copies of the medallion in 
Wisconsin institutions and also to send it out to a greater num¬ 
ber of learned societies.
