the tusks of tlie former for weapons : — is it not because these bones, 

 of which they could not ignore the existence, were fossils in every 

 sense of the word, in their time, that is to say entirely deprived of 

 animal matter and reduced to the nature of stone, and consequently 

 improper (one must, however, except the Silurian mammoth preserved 

 in ice) for the use they wished to make of them. It is impossible to 

 say what period of time was necessary to change this organic matter 

 which constitutes the solidity and tenacity of the bony substance, 

 since the well authenticated remains of early Celtic inhabitants, 

 which we can only allow to have been buried six thousand years, 

 contain it still. In the supposed diluvium of the borders of the 

 Somme one easily understands that objects of this kind are never 

 found, as in the caverns of Aquitaine, where have been discovered 

 so many remains of Celts and the lower animals. 



M. Robert concludes his paper with a quotation from M. Desnoyers, 

 " The Gauls would not have failed to make trophies of the remains 

 of elephants, hyenas, and other grand mammifers, if they had been 

 contemporaneous with man." 



On the Cretaceous Deposits of Central Bohemia. By M. Lipold. 



The Quader or Cenomanian group prevails in the south aud central 

 regions of this district, while the Planer or Turonian group, appearing 

 in isolated hills as far as near Mezeritch, is more exclusively repre- 

 sented in the north-east region. The strata of both, having suffered 

 no disturbance, lie perfectly horizontal, or with a scarcely perceivable 

 angle of inclination. Organic remains are of rare occurrence in them, 

 except in the case of the limestones with Hippurites ellipticus, appear- 

 ing in the south-east, either as isolated coral-reefs or associated with 

 sandstones of the Quader group. 



On the Tertiary and Diluvial Deposits of Central and Eastern Moravia. 



By M. Wolf. 



The tertiaries between Briinn and Olmutz, belonging to the marine 

 deposits of the Vienna Basin, occupy a narrow zone running from 

 Steinabrunn north-eastward between the ranges of the Austro-Moravian 

 hills into Moravia, and filling up, towards Olmutz, several bays, cut 

 into deposits of older date, as, for instance, in. the Zevittawa Valley 

 and around the Mahrisch-Tniban. This northern bay near Briinn was 

 a branch of the north-eastern arm of the sea extending, during the 

 Miocene period, in a north-eastern direction, and connecting, after 

 having passed over the anticlinal of Weisskirchen, the tertiary basins 

 of Vienna and Gallicia. Fossiliferous localities are rather numerous, and 

 among them Rausnitz and Buditz are conspicuous for numbers and 

 variety of organic remains. Of twenty- four species collected at the 

 second of these^places, fifteen also occur at Baden (S. of Vienna), and 

 fourteen at Steinabrunn (N.N.E. of Vienna), so that, as far as evidence
