Abstract
IN NATURE of Sept. 8, p. 349, Mr. A. S. E. Ackermann asks this question. For many years it has been the practice in this Department to dip the fingers into molten lead when lecturing on the ‘spheroidal state’ of liquids. No special precautions are taken to free the fingers from grease, as is commonly advised; they are rinsed under the water tap and shaken to remove drops of water. It is even sufficient, if one finger only is to be used, to moisten it by putting it into the mouth. Of course, the fingers do not remain long in the lead, being withdrawn immediately they are covered, though undue haste in dipping and removal spoils the demonstration.
