as the Glaucomas, Chilodons, and Paramecia, divide themselves with- 
out encysting; others, like the Kolpods, encyst themselves before 
division. After multiplying by division in the interior of their cyst, 
the Kolpods encyst themselves again, and remain in that state until 
the infusion is completely dried up, and they return to life only after 
a fresh moistening. Filters, however, allow small infusoria, such as 
Kolpods, Chilodons, &c., their cysts and eggs, to pass through them, 
X. SCIENCE IN THE PROVINCES. 
Tur numerous provincial Societies, not behindhand in advancing the 
cause of scientific progress to which they have allied themselves, 
exhibit an amount of activity worthy of the cause, and which shows 
itself from time to time in the publication of Proceedings which are 
often of great interest and value. Many of these have forwarded to 
us an account of their labours, and it affords us great pleasure to lay 
before our readers a brief summary, as evinced by these published 
results. Those who disparage everything provincial, cannot fail to 
observe that the Metropolis stands foremost solely because there is 
concentrated, as in a focus, the chief talent of the country; and that, 
therefore, there can be no reason to despise the lucubrations of Societies 
which include the names of Joshua Alder, Rev. A. M. Norman, Albany 
Hancock, Rey. L. Jenyns, W. Pengelly, C. Spence Bate, and many 
others. 
Among such provincial Societies, the ‘ Tyneside Naturalists’ Field 
Club’ occupies a prominent position, and periodically publishes 
Transactions which are full of interest. The latest number is a 
worthy successor to many others. Among the chief objects of this 
Society is the publication of catalogues of the natural productions of 
Northumberland and Durham, and from time to time the Coleoptera 
by Messrs. Hardy and Bold, the Mollusca by Mr. Alder, the Zoophytes 
by the same, the Permian Fossils by R. Howse, the Lepidoptera by G. 
Wailes, and Marine Alegz by G. 8. Brady, have appeared ; while the 
freshwater Aleve, Foraminifera, Echinodermata, Annelida, Crustacea, 
Hymenoptera, Hemiptera, Birds, and fogsil Fish are in progress. The 
present number contains a most interesting “ catalogue” of the Mam- 
malia, by Messrs. Mennell and Perkins, occupying about sixty-five 
pages, and abounding in information both technical and popular. It 
is a model of what such Fauna lists should be, and we wish that every 
county of our island had so excellent a chance of being thoroughly 
examined and elucidated as have those of Northumberland and Dur- 
ham. Fifty out of the sixty-seven wild British species are claimed 
for those two counties. 
Mr. G. 8. Brady, whose attention is directed to the Entomostraca, 
has added several of these organisms to the British lists, by the dis- 
covery of three species of Cypris and two of Candona in the above 
counties, which are here described and figured. One of these, Cypris 
affinis, was known as an inhabitant of the Continent, but has recently
