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^
