10. The spermatoblasts, during the entire metamorp 
remain in organic union with the supporting cell, and, throat 
active and passive changes in the latter, are formed into a 
of spermatozoa. | 
11. The extrusion of the spermatozoa from the wall of the 
tubule follows spontaneous or active severing of their connection 
with the supporting cell, and by lateral pressure from the 
ing adjacent elements. 
12. The various acts of secretion, in every portion of te 
tubuli, overlap in an orderly manner, and in such wise that # 
definite points the successive phenomena coincide in time. 
If we assume the period of metamorphosis of a's 
as a measure of time, we have 
a. The close of each period of metamorphosis of the sp 
matoblasts marks the beginning of the multiplication of 8 
spermospores. : 
6. The beginning of the period of metamorphosis coime 
with the preparatory changes in the spermospores for the pr% 
duction of spermatoblasts. k

- Corresponds to two periods of metamorphosis ; and there are = 
always two crops in process of formation. re. 
d. With the close of each period of metamorphosis there 0 
responds a generation of spermatoblasts, so that at the close 
the metamorphosis, in the same tubule, the material for the

13. In every portion of a testicular tubule a periodic eee 
of spermatozoa and an uninterrupted succession of periods í 
secretion is possible. :
