NOTE—GEOLOG Y. 



Shap Granite Boulder near Spurn. — The recent heavy gales have com- 

 pletely exposed a remarkably fine boulder of Shap Granite near Spurn. It lies 

 on the beach about five hundred yards south of Kilnsea Beacon, but before this 

 notice appears in print will probably have been removed to Mr. Hewetson's 

 garden at Easington. It is sub-angular, roughly measuring 38 x 28 inches ; there 

 are deep strife or groovings in the direction of the long axis. It is smooth and 

 polished-looking, and altogether a most beautiful example of an erratic. The 

 many boulders and blocks of Mountain Limestone, Whinstone, and other rocks 

 partly exposed in situ on this coast, as a rule, seem to show striae running from 

 N.W. to S.E. — John Cordeaux, Easington, November nth, 1889.

Cephalozia Lammersiana near Dewsbury. — In the early part of Sep- 

 tember last I was attracted by the abundance of a bright-green Hepatic in an 

 old brick-pond at Bretton, wide of Dewsbury, tangled among the roots of Juncus 

 supinus and its erect variety, J. uliginosus, which grow there profusely. I sent 

 specimens to my colleague in the secretariate of the Botanical Section, Y.N.U., 

 Mr. M. B. Slater, who states that my gathering is Cephalozia Lammersiana (Hiibn. ), 

 a dioecious species coming very near the widely-distributed monoecious species, 

 C. bicusptdata, and that they were the male plant only. 



The flowers are terminal on the stems, and have single antheridia in the axils 

 of the bracts. Cephalozia Lammersiana is not recorded in ' West Yorkshire ' 

 for the Calder drainage district ; therefore, this will be an addition to the Flora 

 for that portion of the West Riding, in Vice County No. 63. — P. Fox Lee,
