The veflel they are boiledin ought to be capable of holdingat lead three times the quantity ofthe ingredients. As foon as theoil begins to aft upon tlie fulphur,which happens nearly at the pointof ebullition, the mixture raritiesvery much, fo as, if not prudentlyremoved from the fire, to run overinto the furnace; and as the mat-ter is very fufceptible of flame,dangerous confequences may en-fue, efpecially if the quantity islarge.
