163, NUCLEUS IN UNICELLULAR ORGANISMS. 179 
The non-nucleated saprophytes (as Fig. 1, B) may, perhaps, in 
some sense, be looked upon as wholly nuclear, although I have been 
unable to discover anything but the most faint traces of structure 
within them. They present the constant appearance of the nucleus 
when in a totally inactive state, as shown in Fig. 13. 
This appears to present the activities of the nucleus in its 
simplest condition as accessible to our present means. That there 
are phenomena far more delicate than those here recorded, we can 
scarcely doubt, but it would: appear that it is in the unicellular 
organisms that the first lessons in cell-history may be learnt.
