VARIATION NOTES. — Nos. 1-3. 
1. Frequency Curve of White Daisy. — Mr. F. C. Lucas, of 
the Englewood High School, Chicago, who published a paper 
on * Variation in Ray Flowers of the White Daisy," in the 
American Naturalist for | 
1898, has sent us counts made 
on 444 white daisies collected 
along the roadside at North- 
wood, New Hampshire. The 
results are given in the ac- 
companying curve, where the sm- i] T 
number of rays (the class) is 
indicated by the figures at 
the bottom, and the number 
of individuals occurring in 
(the frequency of) each class |__| EE ieee 
is indicated by the vertical 
scale. 3o ery optat

The curve is compound. 
The principal mode is at 21, 
where Ludwig found it for 
European individuals. Sec- 
ondary maxima occur at I3, 
at 24 (— 3 x 8), and also at 
29 and 31. What the latter 
maxima mean is uncertain ; 
Mr. Lucas calls attention to 
the fact that they occurred 
in his specimens from Mass- 
achusetts also. We shall be glad to publish the results of 
counting lots of 1000 to 2000 terminal flowers (only one from 
each plant) from each of various localities.
