the Rev. P. B. Brodie, after having been taken to see that section by 

 the author, communicated to Dr. Wright the notes on it that are 

 published in the paper above referred to. In the first place, Mr. C. 

 Moore described the characters of the Liassic beds at Ilminster, and 

 their relations to the Avicula contorta beds and the Keuper as seen 

 in passing from Ilminster through Beer-Crowcombe to Curry-Rival 

 and North Curry, — a distance of ten miles. He then treated of the 

 subdivisions of the Lower Lias and the true position of the " White 

 Lias ; " and stated that, although Dr. Wright had proposed the fol- 

 lowing classification — 5. Ammonites Bucklandi zone ; 6. A. Planorbis 

 zone (including the White Lias and the Ostrea beds) ; and 7. Avi- 

 cula contorta zone, yet he preferred to groxip them thus — 5. A. Buck- 

 landi zone ; 6. A. Planorbis zone ; 7. Enaliosaurian zone ; 8. White 

 Lias ; 9. Avicula contorta zone : 8 and 9 being equivalent to the 

 " Kossener Schichten " or " Rheetic beds" of Giimbel and other 

 Continental geologists. 



The arguments in favour of his views the author based chiefly on 

 observations made at Beer-Crowcombe, Stoke St. Mary, Pibsbury, 

 Long Sutton, and other places in Somersetshire ; and on a critical ex- 

 amination of the sections at Street, Saltford,&c. as given by Dr. Wright. 



The communication concluded with descriptions of upwards of 

 sixty species of fossils belonging to the Rhsetic beds of England (in- 

 cluding their thin representatives discovered by the author in the 

 Vallis near Frome). Twenty-eight of these species are new.

ADDITIONAL NOTE ON THE CRYSTALS OF LAZULITE DESCRIBED 

 IN THE AUGUST NUMBER OF THIS JOURNAL. 



Dear Sir To Br. William Francis. 



SINCE the transmission of my paper on the American crystals of 

 Klaprothine or Lazulite, I have received a communication from 

 Professor George J. Brush of Yale College, New Haven, informing 

 me that the crystals in question do not come from North Carolina, 

 but from Georgia. They occur at Graves' Mountain in Lincoln 

 County of that State. The North Carolina examples, analysed by 

 Smith and Brush, do not appear to have been met with in crystals. 



Prof. Brush also informs me that these Georgian crystals have 

 been described and figured in a paper by Prof. Shepherd, in the 

 American Journal of Science and Arts, vol. xxvii. (2nd series). 

 This paper had quite escaped my notice, and I have at present no 

 means of referring to it. I hasten, however, in apologizing for past 

 negligence, to point out the fact of its publication. As regards the 

 assumed Trimetric character of these crystals, my views, I may ven- 

 ture to observe, remain unchanged. 



Trusting that you will allow this explanation an early place in the 

 pages of the Philosophical Magazine, 



I am, dear Sir, 

 Sault de Ste. Marie, Lake Huron, Yours very truly, 



July 29, 1861. E. J. Chapman.
