see in a Great Buddhist Temple, or in Heaven ; ” and to 
have come from a great gentleman’s private house.

description of this very curious picture. 
“ On the Microscopic Conditions of a Slab from the Moun- 
tain Limestone of Bolland,” by Professor W. C. William- 
son, F.RS. 
In November, 1845, I laid before the Literary and Philo- 
sophical Society of Manchester my memoir “On some 
Microscopic Objects found in the Mud of the Levant and 
other Deposits; with remarks on the mode of formation of 
calcareous and infusorial siliceous rocks;” which memoir 
was published in vol. viii. of the second series of the 
Society’s Transactions. In that memoir I sought to demon-

equally true and explanatory of the origin of all lime-stones 
except a few freshwater Travertins. 2nd, That some other
