Trigonometry or Conic Sections. You will have to do more with the sections of Codes than of Cones! If you are to take up the medical profession, do not bestow too much of your time on Astronomy. Remember that much waste of time is entailed by frequent changes in your plan of life. Unless you have affluence and leisure, do not lay out too much of your time on mere ornamental accomplishments or in the reading of novels or other works of fiction. When you give your time, give it so as to obtain a fair return of pleasure or profit for yourself or for the community. Do not waste time in pursuits for which you have no natural aptitude.

All I urge is that you should take a rough survey of those fields, and select such as would yield you adequate pleasure or profit. Some fields may have to be rejected, because you lack the requisite aptitude; others, because you have not the requisite means or leisure; others again, because you have no opportunities to practically use the particular kind of knowledge. Be sure, gentlemen, no one will rejoice more than myself to see multitudes of graduates throughout India taking up multitudes of fields of knowledge and cultivating them with diligence, enthusiasm, and success. You have only to
