Note 46 — Chapter VI · PIGEONS—continued.

Mr. W. J. Moore gives a full account of the Ground Tumblers of India (‘Indian Medical Gazette,’ Jan. and Feb. 1873), and says the pricking the base of the brain, and giving hydrocyanic acid, together with strychnine, to an ordinary pigeon, brings on convulsive movements exactly like those of a Tumbler. One pigeon, the brain of which had been pricked, completely recovered, and ever afterwards occasionally made somersaults.
