which has lately been adduced, in favour of the existence of man 

 during glacial and earlier geological times. Ih: Skertclily has 

 found rade stone implements at Brandon, in Suffolk, under 

 conditions which point to their pre-glacial or at least inter- glacial 

 age. On the continent, many anthropologists beheve that prehistoric 

 man appeared in Western Europe in tertiary times, Cappellini has 

 found in certain pliocene deposits in Italy, bones of a whale so cut 

 that he assumes the incisions to be the handiwork of man. At 

 Thenay, in France, the late Abbe Bourgeois discovered rudely- 

 chipped flints bearing evidence of having been burned, in strata as 

 old as Miocene or mid-tertiary times. Below these beds no older 

 relics of man have ever been announced, and indeed the lectiirer was 

 by no means disposed to affirm that the evidence of man's existence 

 in the tertiary period is yet above suspicion.

Mr. Yeo, R.N., Lecturer on Steam at the Royal Naval College, 

 Greenwich, delivered a Lecture on -'The Steam Engine." He first 

 gave some examples of the great power to be obtained by the 

 agency of steam, and of the ease with which this power is controlled, 

 mentioning that H.M.S. '-'Inflexible," a ship weighing 10,000 tons, 

 can be made to move through the water a distance of 17 miles in 

 an hour, with a power which is called 8,500 horse power, but which 

 is really not less than that of 10,000 horses. The lecturer passed 

 on to give a brief sketch "of the history of the steam engine, 

 referring to the contrivances of Hero, the Marquis of Worcester, and 

 Papin, and then described the fire-engine of Savery, the atmospheric 

 engine of Newcomen, and the great improvements introduced by 

 James Watt, which led eventually to the production of the double- 

 acting rotative steam engine in use at the present day. Comparing 

 the steam engine, as it left the hand of Watt, with the atmospheric 

 engine which immediately preceded it, it must be admitted that 

 Watt was the creator, rather than the improver, of the steam engine. 

 The introduction of steam locomotion on land, and of steam 

 navigation, was next traced. Railroads, worked by horses, had long
