154 REVIEWS NEW SPECIES OF PALiEOZOIC FOSSILS, 



tionSj from the Potsdam Sandstone to the Onondaga Group inclusive. 

 In the publication now under notice — an octavo pamphlet of 150 pages, 

 with numerous wood-engravings — the author anticipates, in part, the 

 volumes of the " Paleeontology " that have yet to appear ; being driven 

 to this course by an act of scientific dishonesty, against which we 

 cannot too loudly exclaim. It may not be generally known that the 

 original intention with regard to the publication of the Palaeontological 

 results of the survey of New York, was to issue a single volume merely, 

 with wood-engravings of the more common or characteristic fossils. 

 In furtherance of this view, a number of wood-cuts were prepared ; but 

 in consequence of a more extended plan of publication being afterwards 

 adopted, and copper-plate engravings authorized for the illustration of 

 the work, a few only of these wood-cuts were made use of. The blocks 

 were subsequently obtained, under questionable authority, from the 

 Curator of the State Cabinets of Natural History, in Albany ; and 

 many of the figures were published without the permission of their 

 author. Fearing that the publication of other figures, illustrative of 

 species yet undescribed, may follow, Professor Hall has issued the 

 present volume, with a view to secure himself against being thus fore- 

 stalled. The accompanying remarks, attached to the volume by way 

 of preface, explain these facts more fidly. 



" During the progress of the Report upon the Fourth Geological District of the 

 State, a considerable number of woodcuts were engraved for the illustration of 

 the fossils of the Hamilton and Chemung groups which were intended for that 

 volume. Before the volume was entirely out of the press, the preparation of 

 the Palaeontology of the State was placed under my direction. According to 

 existing contracts with the State, the wood engraving was continued ; and as the 

 first intention was to complete the work on the paleontology in a single volume, 

 drawings were made of the more common and conspicuous fossils of all the suc- 

 cessive rocks, or of all such as I had the means of procuring. 



" However, after ascertaining the great amount of material, and the necessary 

 extent of the work, the plan of publication was changed, and several volumes 

 were authorized ; more extended collections were made, and the work prepared 

 as it has already appeared in the published volumes, in the first of which some of 

 these cuts were used. 



" In the mean time the woodcuts of many unpublished species of fossils, to- 

 gether with others for genei'ic and elementary illustration, intended for the 

 Palaeontology of the State, remained in the custody of the Curator of the State 

 Cabinets of Natural History, until the autumn of 1854, when, under doubtful 

 permission, these cuts were removed from the Geological Rooms, and some of 

 them soon after appeared in a private publication. After much delay, the original 

 woodcuts were restored to the custody of the proper officers, but not until after 

 they had been stereotyped ; and as the stereotypes remain in the possession of the 

 party who first obtained the cuts from the Cabinet, it is in the power of that
