 largely dependent, for a knowledge of his achievements, on the treatises which his son Theodoric wrote. From this source we learn that Hugo recommended, for use in surgical operations, the employment of narcotizing sponges like those described on page 253, and was also an advocate of the plan of treating wounds by the dry method (compresses soaked in wine over which simple dressings were applied).

The first printed edition of his work on surgery appeared in Venice in 1498, and was followed by numerous later issues.

Theodoric, says Neuburger, was a most uncompromising advocate of the dry method of treating wounds. His (Theodoric's) words are these: "For it is not necessary—as Roger and Roland have said, as most of their disciples
