Sixth Meeting: 11th October, 1904.

Dr. Benham, the President, exhibited some excellent photographs of various species of New Zealand Phasmidæ.

Dr. Benham read a paper entitled “Notes on Dr. Bergh's Diagnosis of certain New Zealand Nudibranchs.” (Transactions, p. 312.)

Mr. R. Gilkison read a most interesting paper on “The Treatment of Crimes and Criminals.”

He strongly advocated the classification of criminals, and cutlined the methods that had been adopted in America and elsewhere with this object.

The lecture aroused much interest, and several members took part in the discussion that followed.
