serrated edges fitting together between each two pLatcs whieli makes 



it peculiarly beautiful under an ordinary magnifier. The round part 



of the column so far as it is composed of plates with serrated faces, the 



projecting teeth of one plate fitting into the corre.-pondiug notches of 



those in contact with it above and beh)W, has some resemblance to the 



columns of Schizocnnus nndoms of the Trenton limestone of New 



York, and Glijptoerinm ramuloms of the Trenton limestone of Canada, 



though easily distinguished from both of them. The square i)art of 



the column is unique, and stands alone in form, among all the ciinoid 



columns known to me. The head of the crinoid is wholly unknown and 



consequently the genus to which it belongs is undetermined. 



The slab is in the possession of Dr. R. M. Byrnes at the corner of Itace 



and Fifth streets where it may be seen at any time.

This number closes the second year of the "Cincinnati Quarterly 



Journal of Science," and terminates its existence. We have been 

 induced to cease the publication not only because it is unremuncrative, 

 but for the stronger reason, that the Cincinnati Society of Natural 

 History, having a very large membership and considerable money in 

 the treasury, ought to sustain a publication of its own, either in the 

 form of transactions of the Society, or a Journal devoted to Natural 

 History, and our continuance of this Journal will onlj delay the com- 

 mencement of such a publication. Indeed, it was never the intention 

 to continue the Journal, beyond the period, when it should become 

 evident, that the Society was able and in duty bound to publish its 

 proceedings, if it aspired beyond the collection and arrangement, 

 merely, of a museum. We think that time has come and feel gratified 

 in being able to state, that some steps have already been taken in that 

 direction, with a prospect of a publication at an early day. 



BOOK NOTICES. 



Prof. E. T. Cox introduces' the Sixth Annual Report of the Geolo- 

 gical Survey of Indiana (1874), with the f)llowing declaration : 



"In a paper which I read at the Indianapolis meeting of the Amen 

 can Association for the advancement of science in 1871, attention was 

 called to the fact that thesilurian beds, so well displayed at Chicinnati, 

 were not elevated by a local axis of disturbance, but that the rocks of 

 this famous district simply partook of the general continental flnctua- 

 tions of level. Neither in Indiana nor in the adjoining State ot Olno, 

 e.'^pecially in the region around Cincinnati, have I been able to discover 

 any evidence of a local disturbance or axis of uplift. On the con- 

 tiary, the strata are almo.«t horizontal for many miles, in a westerly 

 course, from Cincinnati. Strata equivalent to these which occupy the
