Abstract
I SHOULD like to remark, in reference to last week's letter on the origin of the screw propeller, that I have long considered the pectoral fins, which are so extremely useful to and prominent upon soles, or the family Pleuronectidæ, as being highly suggestive of this more modern mode of propulsion. Anyone who likes to watch these extremely interesting fish in their swimming movements and graceful gyrations may witness the action and I think attribute to its movements more than is possible in the case of ash and other seed vessels.
