[[red underline]] destructive action of caustic [[/red underline]] soda on glyoxylic acid. and this may explain why in all cases where NaOH accumulates either thru faulty construction of cell or insufficient stirring the yields are lower. I recommended to [[red underline]] try cell without diaphragm [[/red underline]] using an [[red underline]] anode of a platinum [[/red underline]] wire so as to restrict anode or oxidizing surface. Sutherland will try. After long discussions I finally [[luented?]] the [[red underline]] only difference of opinion on the subject of final treatment [[/red underline]] of glyoxylic liquor.
Sutherland says that after neutralization and precipitation of liquor by means of

Sutherland says ammonia as an alkali ought to be added to last filtrate. Then was a discussion between them which had a tendency to become bitter.
I told them scientific men should [[red underline]] not settle [[/red underline]] matters of this kind [[red underline]] by talk [[/red underline]] or arguments [[red underline]] but by direct experiments [[/red underline]] and that we would take up this matter again after these experiments had decided the matter.  They all left seemingly in friendly spirit.
I noticed that both Waldenberger and Sutherland had kept accurate notes of all their experiments and these notes were frequently used during the arguments.
