The stihject of this Essay was presa'ibed in the follotoing ter77is by the 

 Examiners : — -^^A determination of the circtimstanees unda" which 

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

 of maxhnum or mini??zum in the Calculus of Vaj-iations, and 

 applications to particular insta7tces. It is expected that the discus^ 

 sion of the instances should be exejiiplified as far as possible geo^ 

 metrically y and that attention be especially directed to cases of^-eal or 

 supposed failure of the Calculus, "^"^ While the Essay is thus 7nainly 

 devoted to the consideration of discontinuous solutions^ various 

 other questions in the Calculus of Variations are examined and 

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

 extension and i77iprove7nent of our knowledge of this refined depart- 

 ment of analysis.
