NOTES AND QUERIES.

over it in the course of centuries to the depth of eight or nine feet, burying 
alike mastodon bones and Indian traces." 
The discovery of stone arrow-heads mingled vrith the bones of a mastodon, 
elsewhere related by Dr. Koch, is of very little value in determining the original 
question ; for these weapons, which are widely distributed over the state of 
^Missouri, have no doubt owed their spread to water -agencies, during the generally 
accepted human period. — George E. Roberts. 
We are much obliged to our friend, Mr. Roberts, for this note. We had been told 
that the supposed association of man and the " Missourium" had been explained 
away in this case, but we did not know by whom. We think, however, the 
original opinion of Dr. Koch, as supported by the traditions of the Indians, at 
any rate is quite as good a theor}^, and as much entitled to credence as the other, 
— the latter seemingly being an attempt to explain away the circumstances 
noted by Dr. Koch. In all these matters the evidence should be scrupulously 
examined for the sake of truth, and we must ever be on our guard against the 
misleadings of prejudice. — Ed. Geol. 
GONIOPHOLIS AND SUCHOSAURUS REMAINS IN WeALDEN StRATA. — 
Sir, — The fossils which I send for your inspection are from the Wealden strata 
round Cuckfield, Sussex, and I should be much obliged if you would, through 
the medium of " The Geologist," inform me, 1st, whether I am right in the 
supposition that all the teeth with cylindrical liases belong to the genus 
Goniopholis ? — [Yes]. And 2nd, the one which is compressed to Suchosaurus ? 
— [Yes.] (3rd). Does the vertebra, wliich was found associated with the teeth, 
belong to either of these two ? — [Yes]. (4th). Do not all the osseous plates 
belong to Goniopholis ? — [Yes]. And have any dermal bones of the Sucho- 
saurus been found? — [Yes]. (6th;. What is the cause of wide irregular 
grooves on three of the teeth ? — [Varietal condition]. If you will kindly 
answer these queries you will deeply oblige me. — Yours truly, J. C. Ward, 
Clapham Common, Surrey. 
The fossils sent are teeth oi Suchosaurus cult ridens and Goniopholis cmssidens; 
bones and scutes of G. crassidens ; fragment of bone of Tretosternon Bake- 
welli (?) and indeterminable fragments of bones. 
These fossils are from the " calciferous sandi'ock" of the upper portion of the 
Hastings sand. — Ed. Geol. 
Errata in Foreign Correspondence. — Page 196, line 28, " pressure of 
the steam = one seven-eighth'' should read "one and seven-eigths." 
Errata in Geol. of Newport Pagnall. — Page 215, line 17 (from the top), 
for "it takes the place of the Cornbrash of the South of England," read "it 
apparently takes the place, &c. — p. 215, for "Lethbury" read Lathhury. In 
the list of fossils, p. 21 6, for " Modiola plinaba" read M. plicata — for " Cardium 
globosum" read C. cognatus — for "Pecten globosum" read P. arcuatus — p. 216, 
for "Hantwell" read Hart well, and for "Stoke Goddiugton" read Stoke 
Goldington. — J . H. M . 
Extracts from Magazines. — Dear Sir, — Would not a few selected facts 
and memoranda from the monthly and quarterly scientific magazines relating to 
geology and mineralogy be acceptable to many of your readers, as there are 
often discoveries, &c., that occur which are almost unnoticed, at least by many 
who have not time nor opportunity to glance over the journals that may contain 
such information, and which is sometimes very valuable ? These memoranda, 
when brought together in such an excellent magazine as the " Geologist," 
would prove of much interest to those studying the kindred sciences of 
mineralogy and geology. 
I notice in the Philosophical Magazine for April, an interesting paper on the 
existence of a new element, discovered by the spectrum analysis, by Mr. W. 
Crookes, among some seleniferous deposits at a chemical works at Tilkerode,
