298 Bibliographical Notices. 
catalogued and published, besides other matter enough to fill, with 
the catalogues, six volumes of Transactions ; and that they have ac- 
complished something towards promoting a taste for the study of 
natural history would appear pretty evident when we find that nearly 
four-fifths of the matter of the Part of the Transactions just issued 
have been contributed by authors who were school-boys when the 
Club was founded. Moreover there are now in preparation, by 
members of the Club, catalogues of the Birds, Crustacea, Annelida, 
Echinodermata, Foraminifera, Flowering-Plants and Ferns, and 
Freshwater Algze of the two counties (Northumberland and Durham). 
With these completed, we may look in vain, we fear, for another dis- 
trict in England where so much shall have been done towards the 
investigation of its natural history. 
Nevertheless much will then remain for the Tynesiders to accom- 
plish. The Fish, Reptiles, and Amphibia, several orders of the 
Insecta, all the Arachnida and Ceelenterata, various groups of the 
Protozoa, besides all the Carboniferous Fossils, both vegetable and 
animal, will still be left to catalogue. Even with good lists of the 
faunas and floras of their district, they will scarcely have done more 
than have taken a census of the inhabitants of their domain. The 
will know what they have yet to investigate: this much they will 
have achieved ; but the chief part of their work—the true study of 
the various creatures enumerated in their catalogues—will only be 
beginning. For the natural history of any animal or plant, let it be 
ever so lowly, means something more than a pair of Latinized names 
and a string of scientific words for a diagnosis. This, at least, is our 
conception of the matter ; and we hope that it is that of the working 
naturalists of the Tyneside Club, and that they will not rest satisfied 
in cataloguing their natural treasures, but, like true men, will con- 
tinue their labours until they have wrought out the history of them 
also. 
Part II. of the sixth volume of the Tyneside Transactions includes 
the President’s Address for the present year, a catalogue of Mammalia, 
and papers and reports on zoology, geology, botany, and meteorology, 
amounting altogether to about 200 pages. Five plates and several 
woodcuts illustrate the papers. The most important portion of the 
Part is the Catalogue of Mammalia by Messrs. Mennell and Perkins. 
Good local catalogues, even of Mammalia, are still desiderata in English 
zoology ; and these authors deserve the thanks of zoologists generally 
for so valuable a contribution to their science. As the authors ob- 
serve, there are few districts in England in which we might expect 
to find so large a mammalian fauna as in that embraced by these two 
northern counties ; for in it are extensive regions of fells, or moors, 
almost as wild as nature left them, and very sparsely populated, 
where we may reasonably suppose that several of the wild animals 
which have long ago disappeared from other parts of England with 
the progress of cultivation, will still be found to have their retreats. 
Of the 75 species of English Mammalia, Messrs. Mennell & Perkins 
claim 59 as occurring in Northumberland and Durham. They 
remark as follows:—‘ Of the 75 species of Mammalia usually in-
