The part assigned to me today is a humble one. It is not that of the specialist who diagnoses and prescribes for the disease, but that of the attendant who induces the patient to practise the regimen ordered, by persuading him that, repulsive as at first sight it appears, he will find it in reality not only forțifying, but positively agreeable; that it involves the surrender of no habits or activities which a sensible man ought to wish to retain; and that, if only he will pluck up the courage to give it a trial, bc will end by being astonished that he did not take to it before. I am only too conscious of my inability to utter convincingly the reassuring noises which such a rôle requires; but, in doing business with so experienced and wary an animal as the British lion, an approach which allays his initial alarms is undoubtedly expedient, and, not less undoubtedly, the kernel of his apprehensions is to be found in the region indicated by the title of my essay.
