M. Tresca, who has charge of the Conservatoire des Arts et Métiers, the institution which in Paris answers to our Patent Office, says that drawings of new inventions are more useful than models, are cheaper, and are very much oftener consulted.

This engine was tried in the streets of Paris; but when passing near where the Madeleine now stands, it overbalanced itself on turning a corner, and fell over with a crash; after which, its employment being thought dangerous, it was locked up in the arsenal to prevent further mischief.

At the same time he became a student at the Conservatoire des Arts et Metiers, where he attended the lectures, and studied the machines in the museum. He also took practical lessons in turning from a toymaker.
