of Mr Darwin's mantle to carry on Mr. Darwin's work 

 in Mr. Darwia's spirit. 



I have seen Professor Hering's theory adopted 

 recently more unreservedly by Dr. Creighton in his 

 " Illustrations of Unconscious Memory in Disease." * 

 Dr. Creighton avowedly bases his system on Professor 

 Hering's address, and endorses it; it is with much 

 pleasure that I have seen him lend the weight of his 

 authority to the theory that each cell and organ has an 

 individual memory. In " Life and Habit " I expressed 

 a hope that the opinions it upheld would be found use- 

 ful by medical men, and am therefore the more glad 

 to see that this has proved to be the case. I may 

 perhaps be pardoned if I quote the passage in " Life 

 and Habit " to which I am referring. It runs : — 



" Mutatis mutandis, the above would seem to hold 

 as truly about medicine as about politics. We cannot 

 reason with our cells, for they know so much more " 

 (of course I mean " about their own business ") " than 

 we do, that they cannot understand us ; — but though 

 we cannot reason with them, we can find out what 

 they have been most accustomed to, and what, therefore, 

 they are most likely to expect ; we can see that they 

 get this as far as it is in our power to give it them, 

 and may then generally leave the rest to them, only 

 bearing in mind that they will rebel equally against 

 too sudden a change of treatment and no change at 

 all" (p. 305).
