pated the evolution of the Brachiopods, etc., now universally accepted 
by all the leading scientists on this continent. 
The organic remains of the Barton Niagaras are very poorly 
represented in the Museum cases here. When the beds at Russeux 
Creek were first noticed, the banks and bed of the brook afforded 
me some exceedingly fine limestone slabs, thin (like the Anticosti 
ones) and very fossiliferous. They were found zz sztu in the soft, 
muddy shale, a little above the surface of the stream, in the same 
field as the Waterlime Quarry, but beyond it. Some were forwarded 
to the Redpath Museum and to Europe. The few contained in our 
cases are much inferior to the specimens formerly discovered there. 
Great things were expected when the Waterlime Quarry was first 
opened, and when the “‘concealed measures” of Dr. Spencer, F. G. 
S., were laid bare, but the result has been very disappointing. 
Mr. Bartlett informed me he got a specimen of the honey-comb 
coral (Favosites) in one of his visits to the creek last summer. The 
blue shale in which it was found corresponds from the description to a 
very large one obtained by the writer some years ago from the same 
horizon, and that one particularly you may permit me to describe, 
although others subsequently discovered did not precisely corre- 
spond with the outward form of a still larger one, whose internal 
structure you may notice, which I secured for one of the side cases 
of the Museum. I am under the impression I called the attention 
of the Geological Section in a former paper to finding Paleozoic 
corals of considerable size so frequently in muddy sediment. 
The first specimen the writer obtained at the Waterlime Quarry 
presented the appearance of an irregular round mass, with hardened 
shale adhering to it. As it possessed no outward indication of its 
nature, I concluded it was merely concretionary. I only learned 
what it proved to be on breaking it up. Wishing to obtain for Dr. 
Clarke some few Barton fossils, I proceeded to the waterlime beds 
in October last. Although somewhat disappointed at not finding an 
Avicula or specimens of fucoids I particularly wanted, I succeeded 
in getting several of the Waldron Indiana shells. 
One of the best marked Favosites of the Barton waterlime beds 
is Favosites Forbest. The peculiar shape and the irregular distribu- 
tion of the large, angular cells corresponded with the one figured in 
the 28th Report of the New York State Survey received from the late
