This problem in past ages formed an incentive to inventors, and led to the search for perpetual motion, for which, even in these days, some illusionists still strive; but when it was understood that, in obtaining such a result, one of the great laws of nature (equilibrium) could not exist, healthy minds could only look to physical actions for the solution Of the problem and it was Denis Papin who opened the way by discovering the expansive power of steam, and himself constructed a motor founded on this principle. The history of this magnificent discovery is well known, and' the immense resources which steam-engines have given us. To recount them would be to give the history of all modern in dustries. However, this source of motive power has not remained the only one to be employed; and now-a - days we see that engines founded on the ex pensive power of gas play an important part in small industries; and every day they tend to multiply: a clear proof that the subdivision of motive power has become the question of the day. From this point of view, however, the problem has been lately solved in a satisfactory manner by a new means, by the help Of a physical agent from which it could scarcely have.
