come a corresponding knowledge of the frequent inability of drugs to 

 control them ; add to this that, with a fairly intelligent patient, the 

 man M^ho possesses an intimate acquaintance with the morbid change 

 which produces the symptoms has the power of explaining his disease 

 to him, and so successfully insisting upon the requisite conditions for 

 treatment, irrespective sometimes of little, if any, assistance from 

 drugs — such a knowledge can not be attained without a thorough 

 scientific training, and I could multiply examples where this kind of 

 education is as useful as it is to the physician. 



At the risk of being tedious, I can not help repeating that the 

 mental training which encourages the habit of careful observation, of 

 accumulating facts, the reality and truth of which are tested by ex- 

 periment, which sweeps away opinions based upon imperfect premises, 

 which succeeds in leaving upon its pupil a profound regard for accu- 

 racy in all his work, must be a valuable addition to any course of 

 education — an addition, for I should be sorry to urge that it was a 

 complete substitute for any branch of knowledge except it be philoso- 

 phy and metaphysics. How science has superseded philosophy was 

 well told by George Henry Lewes when he wrote : " The method of 

 verification, let us never forget, is the one grand characteristic distin- 

 guishing science from philosoj^hy, modern inquiry from ancient inquiry. 

 The proof is with us the great object of solicitude ; we demand cer- 

 tainty, and, as the course of human evolution shows certainty to be 

 attainable on no other method than the one followed by science, the 

 condemnation of metaphysics is inevitable. Philosophy was the great 

 initiator of science ; it rescued the nobler part of man from the do- 

 minion of brutish apathy and helpless ignorance, nourished his mind 

 with mighty impulses, exercised it in magnificent efforts, gave him 

 the unslaked, unslakable thirst for knowledge which has dignified his 

 life, and enabled him to multiply tenfold his existence and his happi- 

 ness. Having done this, its part is played ; our interest in it is purely 

 historical." — Lancet. 



EDUCATION OF BEAm-CELLS. 



By J. MORTIMER GRANVILLE, M. D. 



THE very interesting and important case recently narrated by Pro- 

 fessor Sharpey in this periodical * recalls one that fell under my 

 owm observation rather more than twenty yeai'S ago. I will state its 

 principal features, without going into details, and then venture to 

 make the two cases an occasion for a few brief speculations which 

 I am desirous of laying before medical-psychologists, with a view to
