Dr. Wallich's article on the Radiolaria contain an amount of interesting information which will amply repay perusal. If our readers will pardon an allusion to our own labours, we may add that the volume before us contains a long essay by the Editor of this journal on the extinct British Wolf. In this article, which occupies nearly fifty pages, the geological and historical evidence of the former existence of the Wolf in the British Islands is fully dealt with, and some curious particulars, extracted from State Papers, Public Records, Privy Council Books, and a variety of other sources, are furnished. "So far as can be now ascertained, it appears that the Wolf became extinct in England during the reign of Henry VII.; that it survived in Scotland until 1743; and that the last of these animals was killed in Ireland, according to Richardson, in 1770, or, according to Sir James Emerson Tennent, subsequently to 1766." For the evidence from which these conclusions are drawn, we must refer our readers to the article in question.
The fourth part of the second volume of these excellent 'Transactions,' recently issued, deserves special notice, since it contains, amongst other things, a series of twenty-three letters, written between the years 1822 and 1841, by and to such well- known zoologists as Richard Lubbock, Hoy, Girdlestone, Selby, Yarrell, and Robert Hamond, and prefaced by short biographical notices of each. This series is communicated by Mrs. Richard Lub- bock and Professor Newton, and will have much value in the eyes of naturalists, not only on account of the many facts thus placed on record, and well worth preserving, concerning the fauna and flora of Norfolk and Suffolk at the lime when these letters were written, but also as affording an insight into the pursuits of some of the many earnest naturalists who flourished in the counties above named in the first half of the present century. We might extract many passages from this correspondence which are well worth quoting, but as the part of the 'Transactions' containing it may be had from the Secretary of the Society, or from the Publishers, for a couple of shillings, we recommend our readers to peruse it in its entirety.
