I was of course aware of the scientific school of self-defence known as "Bartitsu", a blend of Jiujitsu, Boxing, Wrestling and fighting with the Cane devised by Mr E. W.

I was not, however, aware that in fact one might learn to practice this Martial Art in the Modern Day. An entire society exists, as well as Courses of Education, such as Self Defence For Discerning Ladies And Gentlemen should one be in the environs of Coventry.
