Tregony Church deciphered about the same time.*—Various other 
objects were spoken on by Mr. Iago, as having been especially 
attractive during the Excursion—as at St. Columb, Mawgan, 
Rialton, Perran Round, &c.; and, in relation to Lanherne, the 
reverend gentleman exhibited an Ancient Rent Roll, of Sir John 
Arundel, temp. Hen. VIII.; Lanheron was mentioned, and the 
Roll included a year’s account of Sir John’s income from Tin 
produce. 
The proceedings closed with a brief survey by Dr. BARHAM of 
the mining experiences of the Excursionists,—at the Castle-an- 
Dinas Tin Mine, and at the Consolidated Iron Mines. He hoped 
that these works would enrich their promoters, and be a means of 
affording to the public increased facilities for visitng the North 
Coast. The vein of iron, which was about 30 feet wide, had been 
- traced for about 10 miles E.S.E.; and parallel with it, was a fine 
lode of lead. Large specimens of both ores, presented to the 
Institution by Mr. Roebuck, lay on the table.
