ANALYSIS OF MARLS. XXXV 
Water boiled on this marl, takes up an abundance of sulphate of lime and of chloride of calcium. . The 
stone gives off fumes of ammonia on being wetted with solution of potassa. It is also slightly impregnated 
with bitumen, or mineral-tar. 
(4) From the Rey. Dr. Hanckel’s place, at Church Creek, St. Andrews. In connection with this locality, I 
noticed various fragments of fish-remains, and casts of a small Cardiwm, about } of an inch in diameter.

2. Greyish white chalk-marl. 
This is a fine grained, porous, easily pulverized stone, strikin;-ly analogous in its lithological properties to 
the chalk-marls of Westphalia. Its color is greyish white, sometimes tinged brown by iron, and rarely having 
a pale yellow hue, mingled with the grey. It is easily crushed to powder, even with the strength of the hands, 
especially if it is wetted. It is richer in fossil remains and impressions, than the variety first described. The 
most conspicuous of these fossils are an anthophyllum of a conical form, and one inch or more long, a slender 
jointed coralline, a caryophyllia, stem of a pentacrinites? spines and plates of echini, a cast of a small belem- 
nites, of a natica, a fulgur, a ranella,a scalaria, a mytilus, a venus (2 inches across) and cytherea (of about one 
inch,) a cardium and shells of a balanus (1 inch across and } high.) In addition to these, are noticed frequent 
fish remains, as teeth, bones, and scales, as well as irregular fragments of bones, which must have belonged to 
larger animals,
