We have been induced, at the request of several of our readers, to extend these 
notices to the chief periodicals published on the Continent. As it happens that 
more than one of these have commenced a new series with the year 1854, or con¬ 
temporaneously with this Review, we have taken that for the starting point in most 
cases. Having, therefore, to work up back numbers, we make the notices short, 
often abridging the headings of articles, or merely indicating their subject matter. 
In the case of volumes professedly devoted to Natural History or Geology, we have 
seldom ventured to exclude an article on account of its matter being rather out of 
those limits. Other notices, from the serials of a mixed cast, may seem also to 
trench upon the grounds of rural economy, chemistry, pathology, &c., as we have 
sometimes found it hard to draw the line. For the contents of some, which have 
not reached us, we have to own ourselves indebted to the useful half-yearly cata¬ 
logue, Bibliotheca Historico-naturalis, Physico-chemica et Mathematica, of which 
Williams and Norgate are the London publishers. And for material assistance 
derived from the Dublin University Library, we have to thank the officers, and, in 
particular, the Senior Librarian, the Rev. J. H. Todd, D.D., S.F.T.C.D.
