45 8 Water Absorption by Protopla^m [Mar. 



The remaining pages (311 to 315) of Gies's criticism quote 

 various passages from my book in which I touch upon the röle of 

 various enzymes in increasing the hydration capacity of the tissue 

 colloids, and emphasize his view that in these is to be sought a more 

 potent cause for the production of edema than in the acids which I 

 have discussed in particular detail. I am perfectly ready to admit 

 that this may be so, but to repeat what I have already said, in the 

 absence of quantitative studies no one can yet say which of the 

 various factors that may be active are most active. 



Dr. Gies has tried to deal so conscientiously with my work that 

 it will not be regarded as personal criticism if I append to this 

 article a list of my various publications, with their titles, that I have 

 written from time to time on this general problem of water absorp- 

 tion in biological material under physiological and pathological con- 

 ditions. Many a warm criticism that has been launched against 

 me has no better foundation than that the author has found it in- 

 convenient to read more than one of my publications. The Amer- 

 ican reader scarcely deserves blame for this, for the various articles 

 I have tried to publish here have been returned by the editors. I 

 have tried to repeat myself as little as possible in my various writ- 

 ings. Perhaps future critics, if they trouble to enter the discussion 

 at all, will, before publication of their views, study the original 

 sources as carefully as Dr. Gies has generously done.
