EDESTUS NEWTONI AT BROCKHOLES. 
J. R. SIMPSON. 
Asout the beginning of May, 1916, well boring operations were 
commenced at Rock Mills belonging to Messrs. Joseph Sykes, 
and Co. Ltd., Brockholes, near Huddersfield, and by the middle 
of June the work was completed. A plentiful supply of water 
was obtained at a depth of 160 feet, and the bore-hole, which 
was 13} inches in diameter, was finished at 165 feet from the 
surface. 
When the boring passed through the alluvium of the valley, 
it entered the group of shales underlying the Rough Rock 
which forms the highest member of the Millstone Grits in the 
district, and the following notes of the various strata en- 
countered were drawn up during the work.

In the shales at a depth of 120 feet, a remarkably fine fossil 
was found by the engineer in charge, Mr. H. H. Freer. A 
small portion of the fossil, accompanied by a rough drawing 
which I made, was forwarded to Mr. John Pringle of the Geolog- 
ical Survey, who recognised it as belonging to Edestus, a rare 
and interesting genus of Coal Measure fish. A request was 
made for the other portion to be sent, and accordingly it was 
taken to London by Mr. Elon Crowther, senior director of 
Joseph Sykes and Co., who, at the request of Dr. A Strahan, 
kindly presented it to the Geological Museum at Jermyn Street. 
Referring to the fossil in the course of a letter to Mr. Crowther, 
Dr. Strahan said,— It proves to be an unusually perfect 
example of a fossil fish spine of a type which is of the greatest 
rarity in Europe. We have one poor and imperfect specimen
