'We have no doubt that, in considering whether in any particular case the accused acted "with intent to injure", it is necessary to have regard not merely to his intent with regard to the effect which the noxious thing will have upon the person to whom it is administered, but to his whole object in acting as he has done. The accused may, in one case, administer the noxious thing with the intent that it would itself injure the person in question; but in another case he may have an ulterior motive, as for example when he administers a sleeping pill to a woman with an intent to rape her when she is comatose. In either case he will, in our judgment, have an intent to injure the person in question, within the words in the section.'
