120 JOURNAL OF PROCEEDINGS. 
On approaching the end of the quarry close to the road 
fence, many of the upper beds were found encrusted with -a 
skin-like covering of carbonate of lime, which would effectually 
conceal specimens beneath. The material is very adhesive, 
rarely scales off, or is removed partly, perhaps, by the powder 
used in blasting. A small portion of the Graptolite is occa- 
sionally revealed in this way, which otherwise must have been 
unnoticed. ‘The absence of Brachiopods was a remarkable fea- 
ture in the Chert beds of the Webber Quarry; it cannot be 
readily accounted for. The Discinide, etc., so numerous it 
the adjacent ones, being only found ot the brow of the escarp- 
ment (a few turned up), but not another specimen. of the large 
Lingula described and figured by Dr. Spencer (Lingula in- 
gens) was discovered. It only put in its appearance when the 
quarry was first opened some years ago. I was looking close- 
ly for a better one to replace the specimen in the Museum case, 
but in that expectation I was disappointed. It is rare in the 
Chert, and the few secured probably formed a family group. 
All came from the same horizon and were close together. 
Since Dr. J. Clark (Chief Palzontologist of New York 
State) visited our Museum I| succeeded in securing for him an 
“ Aricula”’ he wished to examine, perhaps with one already 
named by his predecessor (Jas. Hall), as well as I can recol- 
lect. I mentioned it represented the only Lamellibranch that 
did not appear to be dwarfed in the Hamilton, Ontario, local 
chert beds. I record this fact, since it has been noticed as 
very remarkable by the late President of the Geological Sec- 
tion (Mr. A. E. Walker), as well as the writer. Indeed, every- 
thing else in these upper layers has a stunted appearance, ex- 
cept the Graptolites and Lingulide. It must not be supposed 
that all the underlying layers in the Chert are unprotected by 
the Erie clay, otherwise the writer would have but very few 
specimens to submit for the Section’s examination. You may 
notice, even in the restricted extent of the Webber Quarry, as 
you approach the road fence, certain patches of this material 
sufficiently thick to preserve from weathering the glaciated 
polish and Striz underneath. It was from one of these
