mensions, and thus completely enclose the form on which the 

 simple plant began. (Plate XV.) We have each and all of 

 these conditions represented in our collections. 



It is a matter of common occurrence to find fossil bones in 

 these beds beautifully and distinctly etched by the growing 

 fibres of those days. (Plate I., figs 6, 7.) We have examined 

 these fibres microscopically, with the unvarying result that all 

 show distinct plant tissue. We have ground sections of iso- 

 lated fibres picked out of the sand rock, and likewise those 

 picked from the fossils on which they originally grew. We 

 have also cut sections from those fibres which were gathered 

 together as plant aggregates or colonies. In each and every 

 case there has been the same display of simple parenchymatous 

 tissue. (See Plate XVI. , figs 1, 2, 3.) 



DAEMONELIX CAKES. 



The next simplest form is that which, for lack of a better 

 name, the students of our party dubbed "Daemonelix Cakes." 

 (See Plate II.) 



They are, in fact, not so unlike camp griddle- cakes in size 

 and thickness, and likewise in the manner in which they, batter- 

 like, threw out irregularly in all directions pseudopodia-like 

 lobes.

These occur very abundantly throughout a layer six to eight 

 meters in thickness, at a depth of fifty to sixty meters below 

 the regular Daemonelix beds. Neither below this horizon, nor 

 above it, are they found. Their form is commonly circular,
