The newtral potassium salt is very easily soluble in hot, as well 
as in cold water, and crystallizes from its concentrated solution in 
needles, Owing to a want of material it was not analyzed. 
The potassium salt, obtained from the monoclinic barium salt, 
on being fused with hydrate of potassium, yielded only oxybenzoiec 
acid, as anticipated.

to obtain further facts which might serve to throw light 
of Eozoon. A remarkable example of a similar pheno- 
menon has been found by him ina limestone from the collection of 
he late Dr. Holmer, marked Llangedoe (Wales), and preserved in
