ON NATURAL HISTORY MUSEUMS. 251 take the form of rudely-chipped implements of stone, found chiefly in river gravels and in bone-caves. Within the last few years, the study of the early remains of man, —remains which are safely assignable to periods far beyond the reach of historical records in Western Europe,—has attracted a large number of students, and has acquired considerable popularity under the name of prehistoric archaeology. Every natural history museum should certainly contain a collection of these archaic remains. How such a collection can be advantageously exhibited may be realised by any one who has visited the Blackmore Museum at Salisbury, where the munificence of Mr. William Blackmore has not only erected one of the most elegant museums in England, but has furnished it with a splendid garniture of specimens, all bearing directly or indirectly upon this one branch of study. The stone implements which form the earliest relics of man's handiwork separate themselves into two groups—the one series rude and unpolished, the other more highly finished—representing the successive phases of culture which correspond respectively to Sir John Lubbock's palaeolithic and neolithic ages. The use of stone was followed by that of metal ; and, according to the Northern antiquaries, whose classification is generally followed by modern archaeologists, the use of bronze preceded that of iron. A local museum is surely a fit resting place for such archaic objects as throw light upon the early history of the surrounding country, and it would be well if those who discover objects of this kind were sufficiently public-spirited to place them in a museum, where they would minister to the instruction of the people and the advancement of science, rather than retain them in private collections, where they are hidden from most students, and are oftentimes in danger of being forgotten and neglected. Bitterns at Maldon and Hazeleigh.—On December 22nd last "Strippy" Clayden and "Cocker" Bundock shot a fine female Bittern in my Brick House sluice, or gutter, as we call it. It was brought to me alive twice the same day, being eventually purchased by Mr. Edward Sadd. On December 31st Mr. Whymper shot a male in Hazeleigh Hall wood, which I have had set up.— Edward A. Fitch, Maldon.
