face, the direction being in all cases the same, from the base towards the 

 point. The cilia themselves, however, could not be detected by the closest 

 manipulation. We hope that his observations on this point will be quickly 

 followed up by other microscopists, and that we will soon have to report 

 that the cilia themselves have been detected. Other extracts from this 

 most fascinating book we would gladly give, but that we feel how difficult it 

 is to select where all is beautiful. The ardent lover of nature will find in 

 it much to gratify his tastes, even though he should not be a professed 

 naturalist ; in it he will be led, with a goodly companion, " over field, and 

 down, in the fresh, dewy morn — he will in fancy listen to the carol of the 

 lark and the hum of the wild bee — he will stand at the edge of the 

 precipice, and mark the glories of the setting sun — he will watch 

 the mantling tide as it rolls inward, and roars among the hollow caves ;" 

 and, we trust, that he will be led to share, with its author, those delightful 

 emotions which the contemplation of the works of the Almighty must ever 

 cause in the mind of the Christian naturalist. Beautiful as we have thought 

 the present work in many of its descriptions, our chief attraction in it has 

 been the bold and manly avowal of Christian principles and Christian pri- 

 vileges which its pages bear witness to ; and we feel assured, that few will 

 rise from its perusal without a more lasting feeling of pleasure and profit 

 than could be produced if such an avowal were absent. 



In these days of almost infidel speculation, it is pleasant to meet with a 

 work which a thoroughly wholesome tone pervades ; and on this account, 

 even were its other merits less, we would gladly hail " The Rambles of a 

 Naturalist on the Devonshire Coast" as a most pleasing addition to our 

 literature. 



A Flora and Fauna within Living Animals. By Joseph Leidy, M.D., 

 Philadelphia. Published in the Smithsonian Contributions to Know- 

 ledge. 4to. Washington, 1853. 



The title of this pleasing memoir is of itself sufficiently explicit to state 

 its purport ; and though, perhaps, the fastidious may be disposed to turn 

 from its pages, to the naturalist they will be found, in a comparatively small 

 compass, to present much original and deeply-suggestive materials of thought 

 and research. 



It may be stated that the recent labours of others in this field of re- 

 search have rendered the publication of the present memoir almost super- 

 fluous. To this objection our author, in his introduction, modestly answers, 

 by stating, that he but professes to give "the result of observations,.
