the author) lo see ai, a glance the specific relationship (so far as at present 
known) whicli exists between tiic life-j^roups of the later palirozoic jieriods. 
The generic alUnity of these gronj)s has long been noticed. This alTinity and 
other anpareiit indications of a want of systematic difference originated the 
proposal that the Permian should be included in the Carboniferous system ; 
and Mr. Kirkby considers that the existence of the several recurrent Carboni- 
ferous species in the Permian rocks strongly supports this view, and that 
" Permian" should be retained only as a subordinate term.

After noticing generally the mica-schists of the district, with its limestone 
or calcareous schist, and occasional roofing-slate, the author proceeded to 
describe first the porphyry-vein (half a mile wide), contaiuiug silver-ore, copper- 
pyrites, grey copper-ore, iron-jjyrites, and molybdena, and crossing a vein of 
non-metalliferous greenstone, at Tomnadasham, on Loch Tay, opposite Ben 
Lawers. He then pointed out the probable connection of the existing great 
valleys with lines of fracture due to igneous violence. The veins at Ardtalla- 
naig, containing heavy spar, and ores of zinc, copper, and iron, were next 
noticed. At Correbuich there are two sets of veins in the calcareous schist ; 
those having a north and south direction contain argentiferous galena and 
traces of gold. The most eastern hills on Loch Tay, in the neighbourhood of 
Taymouth, abound with quart zose veins containing copper-pyrites, iron-pyrites, 
and galena. The iron-ore of Glenqueieh, and the serpentine and chroniate of 
iron at Corycliarmaig, where graphite and rutile also occur, were next noticed. 
At Lochearn Head there are galena-veins in calcareous schist ; here, too, some 
auriferous arsenical pyrites has been found. Lastly the author described iu 
some detail the lead-beariug veins of Glen Fallich and Tyndi'um, which have 
been worked for many years.

H.\mmt;es of Stone and Flint. — The daily discoveries of implements of 
flint and stone throughout Yorkshire and other eouuties in England have often 
caused people to wonder and ask the same questions which are made by 
" Inquirer" in your " Geologist" of last month ; add having been for several 
years a collector and storer of implements of flint and stones, you will perhaps 
allow me through yo'ur pages to make as concisely as possible a few remarks 
on the hammers in my own collection, aud in the public collections in London, 
Dublin, and Edinburgh, from which I have no doubt " Inquirer" and others 
may draw conclusions of such a nature as will satisfy their curiosity, enlighten 
their understanding, and give pleasure to all who make matters of this descrip- 
tion their study. In a magazine devoted to a science of so much importance 
as Geology, it cannot be expected that you can devote so much space to re- 
marks which have not a direct bearing on the subjects to which your pages are 
generally dedicated ; but the finding of so many implements of stone and flint 
at great depths below the surface of the earth, which have been made by 
human beings, having created a great amount of interest, I may perhaps 
trespass more on your space than I otherwise should have done. 
In the collections mentioned there are a great quantity of hammers ; upwards
