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 with 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 theory, 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 bases belong to the genus 

 Goniopholis ? — [Yes], And 2nd, the one which is compressed to Suchosaurus ? 

 — [Yes.] (3rd). Does the vertebra, which 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 of Suchosaurus cultridens and Goniopholis crassidens; 

 bones and scutes of G. crassidens ; fragment of bone of Tretosternon Bake* 

 welli (?) and indeterminable fragments of bones. 



These fossils are from the " calciferous sandrock" of the upper portion of the 

 Hastings sand. — Ed. Geol. 



Errata in Foreign Correspondence. — Page 196, line 28, "pressure of 

 the steam — one secen-eighth " should read " one and seven-eigths." 



Errata in Geol. op 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 Lathbury. In 

 the list of fossils, p. 21 6, for " Modiola plinaba" read M. plicata — for " Cardiuin 

 globosum" read C. cognatus — for "Pecten globosum" read P. arcuatus — p. 216, 

 for "Hantwell" read Hartwell, and for "Stoke Goddington" 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 Tilkerodej
