passed away another of those patient workers 
to whose fidelity science owes so much. Not 
known as a botanist, not a member of a scien- 
tific society, not the author of a scientific paper, 
she nevertheless contributed more to the ad- 
vancement of our knowledge of the fungi than 
many of those whose names are frequently ap- 
pended to scientific articles in the journals. 
Many years ago she began aiding her husband, 
Mr. J. B. Ellis, in the arduous labor of prepar- 
ing and mounting the specimens for the ‘ North 
American Fungi,’ and later for the ‘Fungi 
Columbiani,’ and with her own hands bound 
the books in which these were delivered to sub- 
scribers. Had it not been for her help the first 
of these great distributions—numbering 3,600 
specimens—would have been suspended early 
in its history, and the second—numbering 1,400 
specimens—would never have come into exist- 
ence. To her deft fingers, which wrought so 
patiently, botanical science is indebted for the 
more than two hundred thousand specimens of. 
the fungi which Mr. Ellis distributed to the 
botanists of the world. 
THE death is announced, at the age of seventy- 
five years, of M. Balbiani, professor of embry-

Pasquale Freda, Director of the Station for 
Agricultural Chemistry at Rome; of Dr. 8. T. 
Jakéié, professor of botany and director of the 
botanical gardens, Belgrade, and of Dr. Carl 
Kuschel, formerly professor of physics at the 
Polytechnic Institute at Dresden. 
Mr. F. W. Hopes, with the assistance of 
Mr. A. C. Vroman, is engaged in photograph- 
ing the Prince collection of Amerind idols in 
Santa Fé for the Bureau of American Ethnology. 
This collection, made by Governor L. Bradford 
Prince through several years of effort, has at- 
tracted much attention from archeologists, 
partly by reason of the unique and puzzling 
character of the effigies. 
WE learn from the American Geologist that 
Mr. E. S. Riggs, of the Field Columbian Mu-
