Scientific jiu-jitsu: the Japanese system of physical culture, showing defensive and offensive movements

In an era when Japanese Jiu-Jitsu was only beginning to become known in the Europe and America, Mori Ohashi's Jiu-Jitsu manual was one of the first published in the West.
Ohashi's system includes throws, locks, submissions, "pressure points", and a wide variety of unique conditioning exercises. Definitely useful for the vintage Jiu-Jitsu aficionado.
