point.

precision," but would rather look upon it in the light of a contrivance,
interesting, perhaps, especially to amateur mechanics, as not presenting
any particular difficulties of construction.

NEW TORPEDO.


We illustrate a new form of self-propelling and steering torpedo, designed
and patented by Mr. Richard Paulson, of Boon Hills, Langwith, Notts. That
torpedoes will play an important part in the next naval war is evident
from the fact that great activity is being displayed by the various
governments of the world in the construction of this weapon. Our own
Government also has latterly paid great attention to this subject.

The methods hitherto proposed for propelling torpedoes have been by means
