by some mischievous relative into an inquiring habit of mind. This little boy followed Plattner's lessons with marked and sustained interest, and in order to exhibit his zeal on the subject, brought, at various times, substances for Plattner to analyse. Plattner, flattered by this evidence of his power of awakening interest, and trusting to the boy's ignorance, analysed these, and even, made general statements as to their composition. Indeed, he was so far stimulated by his pupil as to obtain a work upon analytical chemistry, and study it during his supervision of the evening's preparation. He was surprised to find chemistry quite an interesting subject.
So far the story is absolutely commonplace. But now the greenish powder comes upon the scene. The source of that greenish powder seems, unfortunately, lost. Master Whibble tells a tortuous story of finding it done up in a packet in a disused limekiln near the Downs. It would have been an excellent thing for Plattner, and possibly for Master Whibble's family, if a match could have been applied to that powder there and then. The young gentleman certainly did not bring it to school in a packet, but in a common eight-ounce graduated medicine bottle, plugged with masticated newspaper. He gave it to Plattner at the end of the afternoon school. Four boys had been detained after school prayers in order to complete some neglected tasks, and Plattner was supervising these in the small class-room in which the chemical teaching was conducted. The appliances for the practical teaching of chemistry in the Sussexville Proprietary School, as in most small schools in this country, are characterised by a severe simplicity. They are kept in a small cupboard standing in a recess, and having about the same capacity as a
