to which the Adams' Prize was awarded in the University of 

 Cambridge in 1871. Svo. 6s. 



The subject of this Essay was prescribed in the following terms by the 

 Examiners : "A determination of the circumstances under which 

 discontinuity of any kind presents itself in the solution of a problem 

 of maximum or minimum in the Calculus of Variations, and 

 applications to particular instances. It is expected that the discus- 

 sion of the instances should be exemplified as far as possible geo- 

 metrically, and that attention be especially directed to cases of real or 

 supposed failure of the Calculus" WJiile the Essay is thus mainly 

 devoted to the consideration of discontinuous solutions, various 

 other questions in the Calculus of Variations are examined and 

 elucidated ; and the atithor hopes he has definitely contributed to the 

 extension and improvement of our knowledge of this refined depart- 

 ment of analysis.
