the regenerated necks was as good as from the control.

On Dec. 28, 191 2, the necks were removed on two more specimens. 
In one case the specimen with the necks removed shot after 4 days. 
In the other case the specimen with the necks removed did not shoot 
for 7 days when 50 spots were recorded while the check shot the 4th 
and 5th days with 10 and 18 spots respectively. 
On Feb. 12, 1913, the necks on 4 more specimens were removed and 
the test started with a check for each. In three cases the control 
specimens showed expulsion before those from which the necks had 
been removed. The latter averaged 4 days before any expulsion 
occurred. In the 4th case both control and experiment proper shot 
on the 3d day. 
While the number of tests is hardly sufficient to warrant a final
