) of carbide. The
gasholder is of about 200 litres (say 7 cubic feet) capacity; and if the
bell is 850 mm. (= 33-1/2 inches) high, and 550 mm. (= 21-1/2 inches) in
diameter it will admit of the position being read off to within half a
litre (say 0.02 cubic foot)."
The directions of the German Association for sampling a consignment of
carbide packed in drums each containing 100 kilogrammes (say 2 cwt.) have
already been given in the rules of that body. They differ somewhat from
those issued by the British Association (_vide ante_), and have
evidently been compiled with a view to the systematic and rapid sampling
of larger consignments than are commonly dealt with in this country.
Drawing a portion of the whole sample from every tenth drum is
substantially the same as the British Association's regulations for cases
of dispute, viz., to have one unopened drum (_i.e._, one or two
cwt.) per ton of carbide placed at the analyst's disposal for sampling.
Actually the mode of drawing a portion of the whole sample from every
tenth vessel, or lot, where a large number is concerned, is one which
would naturally be adopted by analysts accustomed to sampling any other
products so packed or stored, and there in no reason why it should be
departed from in the case of large consignments of carbide.
