Abstract
BY the courtesy of Prof. Graham Bell we are at length able to do somewhat ampler justice to his latest discovery than has hitherto been possible. He has supplied us with certain details not hitherto published, and has also furnished us with drawings of his apparatus and experiments. Prof. Bell is at present in Paris, and, as was mentioned in our columns last week, has there repeated some of his experiments.
