convert man into a decidedly carnivorous animal, and we do not think that either experience or an appeal to the anatomy of the human masticatory and digestive organs would bear out his views.--_Vide "On Food as a Means of Prevention of Disease._" _Are the Flint Implements from the Drift Authentic?_--A pamphlet has appeared from the pen of Mr. Nicholas Whitley, of the Royal Institution of Cornwall, in which it is attempted to be proved that the so-called flint implements are not the result of workmanship. The _Popular Science Review_ gives the following abstract of Mr. Whitley's argument: (1.) _The "implements" are all of flint._ The tools employed by men of the recognized archaeological stone age are made of stones of various kinds, of which there are examples of serpentine, granular greenstone, indurated claystone, trap greenstone, claystone, quartz, syenite, chest, etc. Why, therefore, {138} should the only weapon in the drift deposit be manufactured from flint solely? (2.) The _"implements" are all of one class--axes_. Were they then a race of carpenters? Man is a cooking animal; and if ten thousand axes have been found, surely one seething-pot or drinking-cup ought to have turned up. He needs shelter, but no remnant of his clothing or hut has been found. Almost everywhere where there are chalk flints we find axes, and nothing but axes. (3.) _There is a gradation in form_ from the very rough fracture of the flint to the perfect almond-shaped implement. Let the most enthusiastic believer in their authenticity examine carefully the one thousand implements in the Abbeville museum, and he would probably reject two-thirds as bearing no evidence of the work of man. But it would be impossible for him to say where nature ended and art began. (4.) Some of the implements are admirable illustrations of the form produced by the natural fracture of the egg-shaped flint nodule. (5.) It is supposed that these weapons were used for cutting down timber and scooping out canoes. But it should be remembered that the gravels in which they are found were formed during a severe Arctic climate, in which no tree but a stunted birch could have grown, certainly none large enough to form a canoe. (6.) _Their number._ The implements are found by thousands in small areas, and in numbers quite out of proportion to the thinly scattered population that must have (if at all) then existed.
