PART FIRST. 



The paper had for its object, not only an account of the 

 development of the locomotory organs of the Radiated 

 Animals, considered with respect to structure, and as a 

 question in animal mechanics merely, but also an exposition 

 of their physiology, with a view to the detection of the 

 principle which Nature has pursued in the evolution of one 

 of the most characteristic functions of the animal economy 

 — Locomotion.
