Romanes continues his research into the locomotor system of Medusae (see AP/57/2). He focuses on the 'naked-eye Medusae', explaining that he has repeated a series of experiments on this species in order to 'confirm the rule previously enunciated, namely, that “excision of the extreme margin of a nectocalyx causes immediate, total, and permanent paralysis of the entire organ.”'. He then addresses the 'covered-eye Medusae', stating that 'this year confirmed all the observations which required confirmation from the fact of their having been at variance with those of Dr. Eimer.'

Annotations in ink throughout. Marked on front as 'Suppressed portion'. Includes one figure and an undated note from Romanes to Walter White.
