With plant No. 250—7 the results are not of importance except 
that we see in practically every case a greater influence by calcium 
nitrate than by water.

Zinc sulfate on plant No. 250—8 did not increase variability 
except in case of the character “number of branches“. Using standard 
deviation alone as the standard of comparison there is also an in- 
creased variability in the number of seed pods.
