ruary 24, 1901. The bright lines seen with the 
slit spectroscope at Ann Arbor may have been 
too narrow on March 13, to show with an ob- 
jective prism. The brightness of the star has 
increased, and was about 3.5 magn. on March 
14. 
Doriew’s excellent “ Lehrbuch der Proto- 
zoenkunde,” the most complete of modern 
works of its kind, met with such immediate 
success that scarcely a year had elapsed before 
he began a third edition. The preface of this 
edition is dated September 3, and the book, 
published by Fischer, has been on the market 
for two or three months. So rapid has been 
the advance of protozoology, that not a chap- 
ter has escaped revision, or rearrangement 
with additions, the net result being an in- 
crease in number of pages from 914 to 1,048. 
In addition to the many new species intro- 
duced there is a new chapter on species, varia- 
tion and inheritance. The author’s attitude 
on special problems has not been changed and 
the parasitic forms, as before, receive the bulk 
of attention. 
A meretine of the members of the Central 
Branch of the American Society of Zoologists 
will be held at the University of Illinois, 
Urbana, Illinois, in the new Natural History 
Building, on April 4, 5 and 6. Thirty-five 
members have expressed their intention to be 
present at this meeting, but it is expected 
that a large number will be able to attend. 
The meeting will begin with a smoker at the 
University Club, on April 4, when President 
Edmund James will address the society. The 
formal program will begin on Friday morn- 
ing at 9:30, with an afternoon program at 2. 
Professor George Lefevre will deliver the 
presidential address at the banquet at the 
University Club on Friday evening. The 
Saturday morning program will begin at 
9:30. There will also be an afternoon pro- 
gram, if it seems necessary. Members of the 
society who expect to present papers should 
send titles to the secretary, Professor H. V. 
Neal, Knox College, Galesburg, Ills., not later 
than March 21. The printed programs will 
be sent out about the twenty-fifth inst.
