G. GENERAL NATURAL HISTORY AND ZOOLOGY. 265 



The establishment of the Delacoste collection does not an- 

 tedate that of Peale in Philadelphia ; but that long since dis- 

 appeared, partly by the scattering of the material collected, 

 and partly from its destruction by fire. 



CINCINNATI ACCLIMATIZATION SOCIETY. 



A very deserving institution has recently been established 

 in Cincinnati, under the title of the Cincinnati Acclimatization 

 Society, its object being to efiect the introduction of such 

 foreign birds as are worthy of note for their song or their 

 services to the farmer and horticulturist. The society an- 

 nounces that during the present spring it expended $5000 in 

 introducing fifteen additional species of birds, and that it has 

 already successfully accomplished the acclimatization of the 

 European sky-lark, which is stated to be now a prominent 

 feature of the summer landscape in the vicinity of Cincinnati. 

 Among the species which it is proposed to introduce is the 

 European titmouse, considered abroad as one of the most suc- 

 cessful foes of insects injurious to vegetation. 



"revision of the ECHINI," BY ALEXANDER AGASSIZ. 



It is well known that the Museum of Comparative Zoology, 

 of Cambridge, in addition to the bulletin of its proceedings, 

 issues a series of " Illustrated Catalogues," in small folio form. 

 In this several valuable papers have already appeared ; but 

 by far the finest and most important is one just out of press 

 entitled A Hemsioii of the Echini^ by Alexander Agassiz. 

 This embraces an exhaustive account of the bibliography of 

 the subject, as well as its synonymy, followed by detailed 

 descriptions of the genera and species, both as regards the 

 external form and internal anatomy. It is illustrated by for- 

 ty-nine plates, of which seven represent the geographical dis- 

 tribution of the various groups oi JEchini^ the remainder being 

 devoted to representations of the species. A very important 

 experiment has been made in this work as to the availability 

 of different methods of photographic printing for natural- 

 history work, and, we may indeed say, with complete success. 

 About one third of the illustrations of species are crayon 

 drawings on stone, one third are Albert-types, prepared under 

 the direction of Mr. E. Bierstadt, of New York, and the re- 

 mainder are Woodbury-tvpeg, executed by Mr. John Carbutt,
