Mr ^\':ilcott"s rltiiin thai his fossils thoiMjii of Ijowit Silurian 
age 3'et resemble those of Upper Devonian strata, will doulitless 
be subjected to eritieism. ])ut the fact must bi' borne in mind that 
in several i)arts of the continent of Kurope the lish are ilistinctly 
Devonian in type, tlioutrji liic niolluscan fauna indicates Cpprr 
Silurian age. This combination is of course very different from 
finding similar fossils in Lmci'r Silurian strata, but may serve in 
a slight degree to lessen the incongruity. 
Microscopic examination was not reported. This lack is to be 
regretted inasmuch as such evidence is really of the first import- 
ance. We hope' that it will Iti' supplied later. 
In addition to the i)lates already mentioned, Mr. Walcott ex- 
hibited certain crinoid-like objects which he l)elieved to be noto- 
chordal or at least t(^ indicate a si)inal column. In our opinion, 
however, their appearance does not warrant such a reference, and 
the ichthyologist will feel grave doulits regarding the preservation 
of such objects from so low an iKjrizon. Further examination 
will, we think, result in a change of opinion. 
Man and the ^Mammoth. 
Among the most interesting exhibits at the recent meeting of 
the International Geological Congress, was that of M. Max 
Lohest of Liege, Begium. Although unfortunately M. Lohest's 
paper was crowded out, and consequent !}• the members had not the 
advantage of hearing it, yet his photographs anil pamphlet were ex- 
amined by several of those who combine archteology Avith geolog}'. 
M. Lohest's paper read bsfore the Anthropological Con- 
gress gives an account of his investigation of the grotto of Spy, 
near Li6ge, on the property of the Count of Beautfort. In this 
cavern M. Lohest found under a thick bed of rul)bish and fallen 
fragments of limestone, three distinct ossiferous beds. The 
uppermost of these was in part stalagmitic, and contained a few 
bones of an undetermined species of deer, a bear's tooth, and 
some pieces of the V)ones of the mammoth. Beside these and 
mingled with them were great numbers of Hint implements of 
various p itterns, some of them resembling the type known as 
"Mousterian, " from the cavern of that name, and others are like 
those found in the well known Engis cave, in Belgium. Some 
are notched like saws and of very thin and delicate workmanship. 
They consist of scrapers, points, blades, knives, etc., worked on
