Stanley Shale Bed, from which it is separated by the Stanley 

 Main, the Warrenhouse, and the Haigh Moor Coal, includ- 

 ing two important beds of Sandstone, — viz. the Horbury and 

 Dewsbury Rock, which overlies the Haigh Moor Coal ; — the 

 other, which is, I believe, denominated the Bradgate Rock, 

 and may be seen near Middleton, Dawgreen, and Thornhill, 

 overlies the Flockton Bed. 



The places where I have observed the working of the 

 Flockton Bed, are Middleton, Adwalton, Cleckheaton, Dews- 

 bury, Overton, and Flockton. The upper part, or roof of 

 this bed, which contains the remains of fishes, is generally 

 called Stone Coal, and is what Mr. Embleton has denominated 

 at Middleton Fish Coal, The roof of the Stanley Shale Bed 

 is exceedingly similar, and indicates a similar mode of form- 

 ation. 



My attention having been directed to the fishes of the 

 Yorkshire Coal Strata, by a fine collection presented to the 

 Museum by Mr. Embleton, I commenced examining some 

 dark shale brought out in sinking a shaft at Stanley, when to 

 my no small surprise and delight, I found that it not only 

 contained detached teeth and scales of fishes, but also nume- 

 rous Coprolites, in the highest state of preservation. Finding 

 these so interesting, I collected a great number of specimens 

 at this locality, and also diligently examined the same shale 

 at Newton Lane-end, at Grove Colliery, and at Westgate 

 Common, at all which places I obtained abundant specimens. 



" The shale containing these remains forms the roof of the 

 Stanley Shale Coal, and is at Stanley six or eight inches in 

 thickness : from the bed of coal upon which it rests upwards 

 it passes into dark bind, which here contains numerous dis- 

 persed remains of molluscous animals, and nodular masses of 

 iron-stone, rich in a small species of unio. This bind, when 

 exposed to the atmosphere for a short time, becomes shivery, 

 and the shells are liberated from the matrix. The shale itself
