THE PRINCIPAL FLOOR. 
chrome iron ore. It usually occurs in serpentinous rocks, and is 
especially abundant in the serpentine of the Shetland Isles, 
which has yielded several of the specimens here exhibited. The 
compounds of chromium are extensively employed in the arts, 
principally in the preparation of pigments. 
Antimony. 
Case 14 . — At one period considerable quantities of antimony 
ore were raised in Cornwall, and some in Dumfriesshire ; but 
none is at present worked in this country. The chief ore is 
the sulphide, called indifferently Antimonite, stibnite , and 
antimony glance. By the side of the samples of this ore are a 
few specimens of Jamesonite, a sulphide of antimony and lead, 
of which enormous lodes occur in Devonshire ; but the difficulty 
of separating the lead and antimony from each other renders 
them valueless. By the decomposition of jamesonite is produced 
the yellow antimoniate of lead called Bleiniere. 
British Gold. 
Case 13 . — There is no metal more widely diffused than gold, 
but it has rarely been found in these islands in sufficient 
quantities to render the search for it remunerative. 
In the tin streams of Cornwall gold has been occasionally 
found. One fine specimen from Carnon stream is in this 
collection, and also some of the smaller grains. Gold has also 
been found in Devonshire, near North Molton, and attempts 
have been made from time to time to work mines supposed to 
produce it. 
There is abundant evidence to show that the Romans actually 
worked gold in Wales ; and Carmarthenshire and Cardiganshire 
have at various times yielded the precious metal. During the 
last few years however, public attention has, been frequently 
directed to the gold-bearing district of Merionethshire ; the 
excitement which, some years back, attended the workings at 
the Yigra and Clogau, between Dolgelly and Barmouth, having 
led to the opening up of numerous other gold mines in adjacent 
districts, but the operations were in most cases abandoned as 
unremunerative. The excitement was renewed, however, on the 
remarkable success which for a while attended the workings at 
the Morgan Mine, near Dolgelly ; but the success was only short 
lived. 
In 1894, the British Gold Fields, formerly the Morgan Mine, 
raised 5,083 tons of gold ore, of the estimated value of 10,019£. ; 
whilst the neighbouring Clogau Mine raised 1,163 tons of ore 
which was valued at 3,217 1. The total quantity of gold 
obtained in Wales during 1894 was 4,235 ounces, of the value 
of 13,573Z. 
Among the specimens in the case before us are several 
examples of native gold from Wicklow, the discovery of which
