 such ability insisted, on the important share which subaerial denu-

I need scarcely add that I do not write for professed geologists ; 

 to them nothing that I have said will be new, and they do not 

 require cautioning : but there must be many of your readers who 

 would accept a statement coming from so high an authority as Mr. 

 Judd without question ; to such I may give a word of warning, and 

 remind them that even Homer was not exempt from the failing of 

 an occasional nap. Whether Mr. Judd was napping, and a vivid 

 imagination conjured up during his dreams a spectre so repulsive to 

 a philosophical mind that there was no resource but to write him 

 down immediately, I can't say. Some great authors are reported to 

 have composed during sleep ; but however the curious mistake into 

 which I cannot help thinking he has fallen has arisen, all who know 

 Mr. Judd will agree that there cannot possibly have been any 

 intentional misrepresentation. A. H. Gueen.

ELEVATION AND SUBSIDENCE OF LAND IN JERSEY. 



Sir, — It may interest your readers to know that in addition to the 

 indications of subsidence of land in Jersey, described by Mr. Pea- 

 cock in his paper lately read before the Geological Society,^ there 

 exist indubitable proofs of elevation of the coast of the island. 



Close by Elizabeth Castle in St. Aubyn's Bay, there stands the 

 picturesque pinnacle of the Hermitage, in the rock of which St. 

 Helerius is said to have impressed his holy body. At the base of 

 the Hermitage, on the northern side, is a very fine raised beach. I 

 have had an opportunity of examining this, and found it to consist 

 of light-coloured, not very coarse, shingle and sand, containing an 

 abundance of shells of species now flourishing on the adjacent shore. 

 I visited this raised beach again in the autumn of 1874, intending to 

 investigate it more carefully, and then found that, in the progress of 

 the harbour works, it had been turfed over and rendered inaccessible. 



On the opposite side of St. Helier's Harbour, under Fort Regent, 

 there is a somewhat doubtful specimen of a raised beach. The 

 harbour works here, however, have disclosed proof that the land 

 stood formerly at a lower level ; the workmen, in blasting and cut- 

 ting back the rock (syenite), have quarried away a sea- worn cave 

 running inland some twenty or more feet, and high enough (so the 

 workmen informed me) to admit a man erect, and containing 

 syenitic boulders of all sizes, rounded and shaped by the breakers. 



A comparison of levels would probably facilitate the determina- 

 tion of the chronological sequence of these (geologically) recent sub- 

 sidences and elevations of land in Jersey. I have not yet, however, 

 had an opportunity of making it. If it be true that St. Helerius ^ 

 lived in the Hermitage Eock, it is at any rate obvious that the littoral 

 accumulation at its foot must in his time also have been a raised
