been found in one of the quarries near Portofspain, but I 
have not seen it. It might throw some light upon the ques- 
tion. Unfortunately, no fossil that I have seen is sufficiently 
decided in its characters for me to pronounce more certainly 
upon the subject. The discovery of a trilobite, a graptolite, 
or an ammonite, would relieve us from a great deal of per- 
plexity, and I feel great faith that some such evidence will 
be forthcoming eventually. 
Some of the beds of the blue limestone have a strong 
resemblance to certain varieties of oolite. A section of this 
exhibits a number of very closely packed elongate-oval 
opaque- grey grains, embedded in a darker material. When 
this rock is weathered, the grains are dissolved out and the 
intermediate material remaining bears a resemblance to 
Stromatopora or Eozoon. 
Organic Remains from the Blue Limestone.

also a massive reef-coral and many serpuline fossils. 
II. On the Discovery of Tertiary Coal at Willi amsville, 
Savanagrande. By B. J. Lechmere Guppy, F.L.S., 
F.G.S., etc. 
Preliminary Notice. 
A short account of the Coal Bed discovered at Williams- 
ville may be of interest to the members of the Association. 
A visit to the spot where the bed is being worked enabled 
me to take a few notes with respect to it.
