spread out again as before, but on a level above that oE the 

 first, and so on for each succeeding layer. 



Be this as it may, the author is led to offer this as a possi- 

 ble explanation, from the fact that examination always shows 

 a distinct organic connection between the lower and the upper 

 members of such a group or cluster of cakes. 



Superficially, the structure of Daemonelix cakes is identical 

 "with that of all the other forms of this strange series. A 

 minuter study shows precisely the same tissue found in the 

 simple isolated tubules, as well as in the more complex forms. 

 We have cut sections from every part of many individual 

 specimens of the so-called Daemonelix cakes, with the result 

 that the cellular structure, perfectly preserved in some slides, 

 imperfectly so in others, was lacking in none. This evidence 

 furnished by the microscope may yet amount to demonstra- 

 tW (Plate XVI., Fig. 3.) 



Let it be mentioned again that the Daemonelix cakes are 

 confined to their particular horizon, some six or eight meters 

 thick, and as far as observation goes do not occur above or be- 

 low this level, unless certain similar, though reduced and at- 

 tenuated, forms found above are their direct survivors. 



DAEMONELIX BALLS. 



Immediately overlying the Daemonelix cakes, we find a form 

 very similar in point of size, appearance, and structure.
