   [1913 Webster]

from Bouvier's Law Dictionary, Revised 6th Ed (1856)

MISPLEADING. Pleading incorrectly, or omitting anything in pleading which is 
essential to the support or defence of an action, is so called. 
     2. Pleading not guilty to an action of debt, is an example of the 
first; and when the plaintiff sets out a title not simply in a defective 
manner, but sets out a defective title, is an example of the second. See 3 
Salk. 365.
