for record in every case, because external conditions, frequently lack of 
light due to shading, have prevented the color from developing to its 
full capacity. Of course, it is unnecessary to say that a multitude 
of conditions in the plant and its environment determines the extent 
to which the color pattern will be developed in a particular bud. 
Under just such conditions, the variability of a character would be 
expected to follow Quetelet’s law, unless there was some disturbing factor. 
Buds were collected from 104 plants, in the manner described, in 
1907, the collections extending from September 27!" to October 11". 
At this time in the season the buds averaged considerably smaller 
than during the earlier part of the summer, though plants which had 
just begun to bloom produced the larger buds characteristic of an 
earlier part of the season. The following tables show the results for
