A quantitative Study of Variation, Natural and Induced, ete. 165 
The table given represents only those treatments which were success- 
ful. If all of the buds treated had developed seeds, then plants 250—ı 
to 250—I4 inclusive would have been almost equally represented in 
the table. Treated buds on plants 250—3, 250—4, and 250—g dropped 
off soon after being injected. Plants 250—13, and 250—14 were 
very susceptable to treatment. Since all plants were worked with 
equal care we have an indication of great variability in the resistance 
of plants to the injection treatment. 
Table 2 gives the data taken on the 1908 (mother) plants as 
regards height of plant, width of plant, number of branches per plant, 
and number of seed pods per plant. Measurement for width was 
taken on but four plants. The figures for height and width represent 
so many centimeters.
