attention of geologists in 1869 in the words which he used more 

 than a quarter of a century ago. The publication of the papers must 

 be equally objectionable to the other authors. 



According to a newspaper report to which we have alluded this is 

 only a small portion of the strange vagary of the Secretary or the 

 Council of the Manchester Society. It is there asserted that all 

 these papers had already been printed by the Society. We have 

 taken the trouble to verify this statement, and in doing so we find 

 that when first published they appeared as abstracts, the "Editor" 

 stating that he must be " responsible for the fidelity with which the 

 views of the authors are abstracted." In the part before us the 

 various authors are made responsible for these same unaltered ab- 

 stracts ! Furthermore, one of the six republished papers has had 

 the remarkable honour of having appeared three times in the 

 Society's publications — on the first and last occasions as the joint 

 production of two authors ; while in the intermediate appearance, 

 having received some verbal alterations, it is ascribed to one of 

 them !

1. " On two new Species of Gyrodus." By Sir Philip de Malpas 

 GreyEgerton, Bart., M.P., F.E.S., V.P.G.S. 



The author remarked upon the characters of the genus Gyrodus, 

 of which he described two new species, namely, G. Goweri, from a 

 deposit of Oolitic age on the east coast of Sutherland, having the 

 scales covered with a somewhat reticulated raised pattern, inter- 

 spersed with granules ; and G. coccoderma, from the Kimmeridge 

 Clay of Kimmeridge, having the scales adorned with a multitude of 

 symmetrical granules, which show no tendency to coalesce. The 

 author also described a vomer of Sphcerodus gigas, bearing teeth of 

 the form usual in that genus, and remarked that this specimen 

 established the validity of the genus SpJicerodus. 



2. " Note on a very large Saurian Humerus from the Kimmeridge 

 Clay of the Dorset coast." By J. W. Hulke, F.E.S., F.G.S. 



This stupendous limb-bone, 31 inches long, was obtained from 

 Kimmeridge Bay by J. C. Mansel, Esq. It had a subcylindrical 

 shaft, a transversely elongated proximal, and a cubical distal ex- 

 tremity. The distal end is mapped out by a wide shallow posterior 

 groove, and a narrower but deeper anterior notch, into a couple of 

 condyles, of which the inner or posterior is the larger. The anterior 

 border of the shaft towards the proximal end rises, as if to form a 

 deltoid crest. The cortical tissue of the shaft is remarkably dense 

 and polished. There is not any medullary cavity, but the interior of 

 the cortex is filled with cancellous tissue. 



The author pointed out that the form of the terminal surfaces 

 removed the bone from all tlie Enaliosaurians, and brought it into
