Many of those interested in geology are by time generally forbidden, and perhaps by inclination equally restricted from the investigation of details on a holiday trip. Nor need this be regretted, for the greatest pleasure in science is not always to be gained by the examination of details, but rather in the contemplation of results derived from such an examination.

In 1863 the skull and a portion of the skeleton of a large extinct species of Ox (B. primigenius), which had been found in the peat of the Cambridgeshire Fens, and which apparently had been killed by a celt, was placed in the Woodwardian Museum at Cambridge. At the time of its deposition there a portion of the flint remained firmly fixed in a fracture in the frontal bone, being partially retained in sitû by a mass of peat: as, however, this peat gradually dried, it crumbled away, and the celt became loosened and displaced; moreover, some small fragments of bone fell away from the margin of the wound, so that in its present condition the specimen merely exhibits an irregular fracture in the forehead, in which a fragment of a flint implement lies loosely; but it no longer furnishes conclusive and positive evidence to prove that the fracture was actually caused by the celt which occupies it.

In a letter to Nature for 14th May, 1874, Mr. Belt has expressed his belief that the presence of shells in glacial deposits, at whatever elevation they may be found, does not necessarily constitute a proof that the land has been depressed to that extent relatively to the level of the sea; but that in such cases as those of the drifts of the basin of the Irish Sea the shells occur in their present positions because they were thrust thither out of the bed of the sea by the ice-sheet which was advancing from the North.

Some specimens of dark olive-grey mudstone from Peeblesshire, collected and shown to me by Mr. D. J. Brown, contain several internal and external casts of small bivalved Entomostraca.
