“It has been shown that the courtship of the octopus (O. vulgaris) is conducted with the utmost propriety and delicacy, and not brutally, as had been the common supposition. The male gently stretches out his third arm on the right, caressing the female with its   extremity,  and finally passing it into the chamber formed by the mantle. There is a quick, spasmodic contraction of the female, but she does not attempt to escape; and if “ the poor beetle that we tread upon, in corporal sufferance, finds a pang as great as when a giant dies,” who shall say that the sexual delight is not equally intense among these diminutive sensualists, and that the hour, sometimes employed in the sexual act may not be, in some sort, a nearly eternal paradise to these tiny existences?”
