II. On the direct synthesis of ammonia

The action of induced electricity on mixtures of certain gases has been lately shown by Sir Benjamin Brodie (Proc. Roy. Soc. April 3, 1873) to yield very interesting results. An obvious application of his method was to treat a mixture of dry hydrogen and nitrogen in a similar manner as those referred to above, with the view of effecting the synthesis of ammonia; and Sir B. Brodie kindly allowed me the use of his apparatus for the purpose of the experiment, which was conducted as follows.
