Give said delegates instructions as to the wishes of the society, and how they shall vote as to the majority or minority report on the constitutional amendment.

Be honest and useful, charitable and prompt, and never neglect the widow or the orphan, and in doing so you will be only second to the angels in heaven.

An erection is induced by one of three ways: (1) By an increased influx of blood to the organ; (2) by a diminished efflux of blood from the organ; (3) or by a combination of both of these conditions. The first of these conditions, the increased flow of blood, is produced either by stimulation of the nerve centers or from peripheral irritation of a nerve. The second condition, that of congestion, is the result of mechanical compression by certain muscles, assisted by the peculiar anatomical arrangement by which the veins at the base of the penis twist at their points of exit from the corpora cavernosa and spongiosum. There comes about first, a relaxation of the muscular fibres in the trabeclae of the corpora
