thorns at the point of junction of the contre and of the vein, 

 giving off a branch 1 10 fathoms in length, along the eastern 

 part of the same vein. 



Another singular circumstance in this mine is, that one of 

 the cross courses is heaved and intersected by an E and \V vein. 



Since the beginning of 1801, there have been sold about 

 45,000 tons of copper ore, the produce of Huel Alfred, for 

 the sum of about 350,0001. of which the profit, divided among 

 the adventurers, has amounted to about 120,0001.

. A paper by William Cony beare, Esq. M. G. S. " On the ori- 

 gin of a remarkable class of organic impressions occurring in 

 nodules of flint/' was read. 



This paper, which is chiefly occupied by detailed explanations 

 pf the drawings by which it is accompanied, relates to a class of 

 substances thus characterized by Mr. Parkinson, in the second 

 volume of his work on organic remains. 



" Small round compressed bodies not exceeding the eighth 

 f* of an inch in their longest diameter, and horizontally disposed 

 '\ are connected by processes nearly of the fineness of a hair, 

 H which pass from different parts of each of these bodies, and 

 " are attached to the surrounding ones j the whole of these 

 f* bodies being thus held in connexion." p. y5. 



Mr. Parkinson conjectures, that the fofmaton of these bodies 

 has been the work of some polype similar to those by which 

 the common zoophytes have been constructed, and, therefore, 

 classes them among fossil corals of unknown genera. He ob- 

 serves, however, at the same time, that his reason for this 

 arrangement is only a very slight analogy, as the objects in 

 question differ materially from every known zoophyte, recent 

 or fossil. 



Mr. Conybeare having been so fortunate as to obtain several 

 specimens of this fossil in a much better state of preservation 

 than usual, shews clearly that they occur between the bony 

 plates of a large bivalve shell, the Csirco-pinnite of Walch, 

 and in a similar situation in fragments of a striated shell, one 

 ol the pateliites of Da Costa, which more probably, however, 

 pelor.gs to the genus ostrea. Similar substance.* have also
