NOTKS AND QUHKIK;

want of a critical guide for the unlettered student, but the faulty pronuncia- 
tion in vogtu; seems little likely to be corrected without a good standard of 
reference \iiorc ready at hand than dict ionary and gradus. We may remark 
that, besides those " instances mentioned by Mr. Eley, several of which, 
especially aflfi'nis, giganteus, concavus, cdulis, are sldom rightly spoken among 
geologists, tiicre is the frequent nus()ronunciation of such words as the gcne- 
tives of proper names ; thus, Milleri wrongly for Milleri, Scouleri for Scoulcri, 
and the like ; also Ganoidea, Crinoidea, Cystidea, &c., are not always thus cor- 
rectly pronounced. We may, however, remind tyros that family names, such 
as Ostreida;, are to be pronounced as Mr. Page thus mai-ks, not Ostreida;, as 
it is iueorreetly and too commonly spoken. 
In Mr. Page's list at p. 40, multitidua has no accentuation, it should be raul- 
tiffdus — too often pronounced multilidus m-ongly ; so also quadi-ifi'dus and tri- 
fidus. Hemispherieus (p. 398) should be hemisphairieus. Possilis (p. 396) 
should be accentuated fossilis. Cervical at p. Ill should be Cervical, not 
Cervical. 
We here add some other corrections which have been pointed out to us by 
another correspondent, and we hope the book wiU be all the better for such 
criticisms in the next edition. For its sake we are open to receive more 
notes of corrections, so that both tyro and Mr. Page may have the benefit 
thereof. Digitalus, finger-like, should be either digitalis, belonging to a finger, 
or digitatus, fingered — formed as fingers ; dorsalis should have its accent on 
the middle syllable ; gagateus may be accented thus, gagateus. In the Latin, 
Konig should be spelt Koeuigius ; so also Noeggerathius. Longimauus wants 
the accent at p. 401. The correction of psilopora for the incorrect psilopora 
(p. 409), and tubipora for tubipdra, may remind many of the common wrong 
pronuucation of the multitude of names of corals and bryozoa partly composed 
of pora, a pore. Pygmains, unaccented at p. 409, shoidd have its peuultmiate 
a misprint tor pusillus, and Rankiuei for Raukinei. Saxatilis at p. 410 should 
be Saxatilis. Toliapicus (p. 414) has, we beheve, a reference to Tolapia, or 
some similar form of the Latin name of the Isle of Sheppy. Umcolor should 
take the place of the incorrect imicdlor. Majandrlnus should be placed for 
meaudi-inus, Macrostomus for macrostomus. Moniliformis and monilitectus 
monUeformis, etc. Muensteriamis for Miinsterianus (after Count Miinster). 
Cypridina-Schiefer (p. 137) should not be half Latin haK German, but as the 
Germans have it, Cypridinen-Schiefer. 
We would suggest that the description of Bracliiopoda at page 96, may be 
corrected thus : — " which they caimot uncoil and protrude, but with which" etc. 
Slickensides. — Deaji Sir, — I was much interested by the queries and re- 
5 lies, upon the subject of slickensides, in the last nujiiber of the " Geologist." 
'hey are very abundant ia the Keuper sandstone of Chesliii-e, and the south- 
west of Lancashire. Usually, two polished striated surfaces exist together, 
but not always, for occasionally a single slickenside is only opposed by a soft 
sandstone, without any trace of such an appearance. Those said to be two 
feet apart, I tliiuk can have no connection with each other. Faults are very 
numerous in this neighbourhood ; in width they vary from an inch to twenty 
yards. They are always filled with sandstone, very much harder than the 
strata bounding them, while at each side sHekensides abound. K the strata at 
each side of the fault is removed, the enclosed compact rock stands across like 
a wall, beautifully polished and striated upon each side. In such cases it is 
evident that the polished sm-faces could not have been caused by the original 
j disruption of the strata, but aftenvards — long after the fault had been filled by 
debris. I am therefore of opinion that a throw of the strata to a very small 
extent, acting under iuuiieusc pressure, was suflicieut to cause the phenomena.
