the agency of animalcules in the for¬ 
mation OF LIMESTONE. 
a Meeting of the Ashmolean Society, held on the 2nd of 
March, a paper was read by Professor Buckland on the 
a gency of Animalcules in the formation of Limestone. Dr. 
Auckland began with exhibiting some polished thin slices of 
Stonesfield slate, lately presented to him by Mr. Tennant, 
^hicli Mr. Darker has discovered to be crowded with micro¬ 
scopic shells: he also announced that Mr. Darker and Mr. 
Tennant have discovered microscopic shells to abound in thin 
slices of certain strata of Derbyshire limestone; and pro¬ 
ceeded to discuss the question how far the abundant occurrence 
°f such remains in the carboniferous and oolitic limestones, 
an d in the chalk and tertiary formations, justifies the revival, 
^hich has been attempted since the microscopic discoveries of 
Lhrenberg, of the old and false dogma— omnis calx e vermibus, 
0rri7 iis silex b vermibus, ornne ferruni b vermibus. 
Hr. Buckland exhibited the plates of Ehrenberg’s work on 
he anirnalcular constitution of chalk (1839), in which he has 
described and figured specimens from twelve localities in 
Europe, Asia, and Africa, all of which are crowded with 
^raminiforous and other minute chambered shells, varying in 
? 1Ze from -^ T th to -^th of a line, so that a million may occur 
p a cubic inch of chalk. In specimens from the north of 
Europe, the quantity of inorganic earthy chalk exceeds that
