Excerpt from Laboratory Exercises in Electro-Chemistry: Ten Laboratory Exercises to Accompany the Course of Lectures on Electro-Chemistry Return of Apparatus. - The apparatus needed for each days work will be found at the student's working place, clean and ready for use; with it is a list, which should be checked over. At the close of the exercise the glass apparatus should be cleaned and collected together, and the burettes and pipettes filled with chromic acid mixture; each student should sign the list, noting any breakages, and leave it with the apparatus. All wires should be left neatly coiled, as found; and in particular all connections to the terminal boards must be broken; neglect of this precaution may lead to serious damage. A fine of one dollar is imposed for the first offence against this regulation, and five dollars for the second. Care of Instruments. - The cost of repairing damage to instruments will be charged against the student or group of students responsible. In setting up circuits the connections to the terminal board must be made last, after the other connections have been checked over. One of the wires of the 110 volt supply is grounded; if a lead from the other wire should accidentally come in contact with a gas pipe or water pipe an accident might ensue, perhaps an instrument might be burned out. The chemicals with which the student works are a special source of danger. Acids, salt solutions, etc., on the hands or spilled on the table may easily get on the instruments, on books, or on the clothes. Every working place is provided with a sink and towels; any chemicals spilled should be cleaned up immediately. Iodine, Silver, and Mercury residues. - On each table receptacles are provided for waste liquids, etc., containing iodine, silver, or mercury respectively; all such residues should be poured into the proper receptacle and not down the sink. At the end of the term these wastes are worked up and the values recovered. Care of Sinks. - Mercury and its salts are particularly destructive to lead, and should never be allowed to get into the sinks. Receptacles are provided on each table to collect used mercury, calomel, and solutions containing mercury salts; there is thus no excuse for throwing them into the sinks.
