Newhaven, while the geological position of the Websterite and 
Allophane was peculiar. 
Mr. Merririetp remarked that a seam of Websterite could be 
traced in the chalk cutting at the Cliftonville Station. 
Mr. Howett also exhibited flint intercalated with Websterite, 
rolled chalk, obtained 7 feet below the surface at the bottom of New 
England Hill, and a fossil Mammalian tooth, found in the main 
drainage excavations in 1866, in drift chalk. 
Mr. Arpiey exhibited specimens of jet, ammonites, belemnites, 
and impressions of leaves, recently obtained by him at Whitby. 
Dr. Bapcock exhibited specimens of sea-weed, Sargassum vulgare, 
obtained by him in the Gulf Stream in 1864.

AND SECTION CUTTING.” 
Dr. Hatiirax gave practical instruction in his methods of 
making sections. Starting with a Beck’s section-cutting instrument, 
intended especially for making wood sections, he had found that the 
accurate workmanship and delicate screw enabled him to make sections 
1000th part of an inch thick. 
For soft substances, with the gun-metal block and a slip of 
paper, he contrived a cell, into which he poured melted wax, —
