MISCELLANEOUS NOTICES, &c. 79 
—SE. Dr. Rimell states that these beds can easily be worked and 
are situated about450 yards from the seaside. We may mention 
that the H. G. S. Nemesis , Capt. Wallace, on her last voyage from 
Borneo to Singapore, when she did such good service against a fleet of 
Ramin Pirates, used Lahuan coal, which burned remarkably well; 
and was considered, Mr. Brooke mentioned to us, to resemble can- 
nel coal. 
Principal fracture, imperfectly foliated fibrous; lustre, glimmer¬ 
ing resinous like that of cannel coal; numerous minute, mostly 
round, pyritous specs adhering. Cross fracture, large, imperfect 
conchoidal; lustre resinous, remarkably splendent, semi-metallic; 
In some places thin layers or zones, irregular in size and distribution, 
nearly perpendicular to principal fracture,—fracture in plane of 
zone irregular, uneven, dull,-—cross fracture uneven, lustre duller 
than body of specimen. 
Moderately hard and tough. 
Small fragments burn slowly in weak flame of spirit lamp with a 
large yellowish and yellowish white flame, no jets, occasional slight 
decrepitation, intumescence slight; removed from lamp flicker and 
die out quickly. 
33 grains gave 19 . 75 grs. of charcoal or cinder, which, on 
incineration in platinum foil until every particle of carbonaceous 
matter disappeared, left . 40 gr. of a reddish yellow or dull 
orange ash'—the reddish tinge being probably derived from the 
Iron in the pyrites
