Injection is then madeof 10 of the 1 per cent, solution, while the needle is slightly movedto and fro, thus distributing the solution on a certain length of thecanal. Paresthesias are exceptionally induced during these manipula-tions, the anesthesia being secured by the diffusion of the solution inthe connective tissue in which the nerve is embedded.
