In the latter no mention is made of the fine wires which areproduced by spattering the molten metal by dropping it from a height upon a glass plate, for at thattime wide strips were desired for radiomicrometer vanes. Both fine wires and thin plates are unavoidablyproduced by this method, which at that time seemed of too little importance to merit a letter dated Nov. 16, 1914, Dr. Pfund challenges the priority of this method as compared with his,which consists in hurling the molten material across a glass plate. No priority is claimed nor note is added in response to the request of the aggrieved party that the matter be set aright in print. Cobientz] Stell
