actly the idea which the antients had of the phoenix"; that is 

 to SUV, that it nourished and n^produced itself. It is seen 

 in tlie Indian mythology that these people deified the coco- 

 nut tree in the same manner as nianv other trees and small 

 vegetables; useful animals, such as the ox; the sea, and all 

 rivers. The Egyptians and all the neighbouring nations 

 adopted the mvthology and fables, as well as the arts and 

 sciences, of these people, as is fully proved by researches 

 made for more than half a century : the Egyptians, the 

 Tyrians, and the Greeks deified therefore, like the Hindoos, 

 animals, useful vegetables, and rivers. Hence the ox be- 

 came the god apis, and the date-tree tlie phoenix ,

 3d, Siliceous Ironstone. 



X HE varieties of this ironstone arc in general much poorer 

 in iron than the common qualities of ironstone : from 1.5 

 1.0 25 per cent, seem to be the medium contents in metal. 

 .Some specimens have been obtained as high as 35 per cent, 

 and 3S per cent. At first sight this class of ironstones re- 

 semble sandstone ; but, upon minute examination, there 

 ;;p})ear otljer characteristic features, of which density is al- 

 wavs one, to distinguish them from each other. 



The vaj;ieiics of this class are, like the argillaceous and 

 calcareous, found both in balls and in regular strata, and 

 ?ubiect to the san»e general rule, i. e, the thicker the band 

 or stratum, the less metal will be found in a given quantity 

 of the ore. Siliceous ball ironstone is ger.>irally rich in 

 iron, and is commonly found with a fracture more or less 

 granulated resembling a coarse variety of freestone. What 

 disiiin'^uislits it fronj sandstone is the calcareous earth that 

 is found in the state of chalk, and which appears in some 

 nicasiire to be ihc seat or bond of union of each individual 

 granule of ore.
