CONCENTRATION OF EXTRACTS 297 



amitotic 1 divisions (figs. 94, 95) were induced in these 

 granular red cells. The granular red cells of normal 

 and other persons have never hitherto been seen to 

 make any attempt to divide on auxetic jelly or any 

 jelly, and hence it appears that these cells from these 

 cancer patients are also more prone to divide than 

 those of other people. 



Since it has been shown that the reproduction, 

 certainly of lymphocytes and leucocytes, and possibly 

 of other cells, depends (on the microscope slide) on 

 the quantity of an auxetic absorbed by them, it is 

 reasonable to suggest that the plasma of these cancer 

 patients contained some such agent which caused this 

 inclination to divide on the part of the large lymphocytes 

 and red cells. Presumably this is the same agent 

 which had been previously found to cause excitation 

 of amceboid movements, and the discard of granules 

 for the combination of stain and atropine will also 

 do this as well as cause augmented divisions. 



It is interesting to note that it is only the red 

 cells which have granules which can be induced to 

 divide, for it bears out the theory that the auxetic 

 contains a specific agent which induces cell-division 

 by acting on cell-granules. 



We may now return to the study of the extracts. 

 It may be remembered that we had only succeeded 

 in inducing divisions in lymphocytes and leucocytes 

 with the artificial azur dye. Extracts of several 



1 We are uncertain whether some of the granular red cells were not 

 dividing mitotically (fig. 95), as their granules appeared to be arranged in an 

 indefinite figure.
