taken for the true glacial beds. The more recent deposits are Brick- 

 clay, Freshwater Shell-beds, and Peat. During the period embraced by 

 the glacial deposits the highlands of N. Wales were above water ; 

 glaciers descended from thence, and the local material thus brought into 

 the sea was mixed with that brought by ice from more northern regions. 

 The paper concludes with a short bibliographical list. W. T.

 Beds with non-local boulders in the bottom of the valley, from Hebden 

 Bridge to Wakefield, are attributed to postglacial submersion.

The cave was inhabited by hyaenas during the deposition of the lower 

 and middle deposits (see Mello, p. 25). The other animals found were 

 introduced by the hja^na. The cave was visited by man during the 

 deposition of the cave-earth, and was inhabited by him during the 

 breccia-period, when it was rarely visited by hyaenas. A list is given of 

 the animals found. The implements of the cave-earth are chiefly of 

 quartzite and rude in form ; those of the breccia are chiefly of flint and 

 of better manufacture. There is no evidence of the relation of the 

 deposits in this cavern to the Boulder Clay. W. T.

 Improvements in the bed of the Clyde have reduced low-water level 

 in Glasgow Harbour 8 feet since 1758. In widening the side, and exca- 

 vating docks, manj' boulders, some weighing 6 tons, have to be removed 

 from the Boulder-clay by means of diving-bells. C. E. D.
