253 & 254. Magnetic Iron 
Ore, pisolitic, contains 54 per 
cent, of metal. 
From a bed of great thickness, 
supposed by some authors to be a 
dyke, {in the Bias') at Rosedale, 
the S. W. part of Cleveland, 
Yorkshire. 
{Vide Transactions of the North of 
England Institute of Mining Engineers,

Wall-case 48. 
Haematite, Red Haematite, or 
Red Iron Ore {cinJiydrous sesqui- 
oxide of iron). Iron, 70 ; oxy¬ 
gen, 30. This rich ore, distin¬ 
guishable from the last by its red 
streak and the absence of magnetic 
properties, is obtained in small 
quantities in Cornwall, Devon, and 
South Wales, but to an enormous 
amount, and of the finest quality, 
iu North Lancashire and Cumber¬ 
land. 
The term specul. 4R, from spe¬ 
culum, fxmii'vov, is commonly given 
to the brightly crystallized varie¬ 
ties of this species.
