steam
or compressed air, and was characterized by its noiselessness and by the
care with which it was manipulated.

Assuming the car, by itself, cost the same as an ordinary tram-car, the
extra cost relatively to other systems was stated as being according to
the following figures, viz.: the Gramme machine cost L48, the motor L208,
and the accumulators 2.25 francs per kilogramme (10d. per pound). To
these must be added the cost of erection, and of switches for
manipulating the current; as well as the proportion of the cost of a
fixed engine to create the electricity.

Having thus given a general description of the various motors which were
presented for competition, I will now give a brief summary of some of the
principal particulars obtained during the competition. In the first

The original programme of the conditions which were laid down in the
invitation to competitors, as those upon which the adjudication of merit
would be awarded, contained twenty heads, to each of which a certain
value was to be attached; and, in addition to these special heads, there
were also to be weighed the following general considerations, viz.:

a. The defects or inconveniences established in the course of the trials.

b. The necessity or otherwise of turning the motor, or the carriage with
motor, at the termini.
