Another excellent book by Eric Shahan.

Although, not directly concerned with Ryōi Shintō-ryū Jūjutsu, it does give translations of material (previously only available in Japanese) on a number of Edo and Meiji period Jūjutsu schools.
I recommend this whole series 1 - 4 to anyone wishing to gain incite into the practice of Jūjutsu during the above eras.
