Experiments were carried out to study quantitatively the influence of various organic colloids in different concentrations on the conductivity of the same electrolyte, that is to say, the influence of albumine, globuline, gelatine, and saponine on the ions Na and OH. Albumine and globuline are colloidal components of serum wherein also both ions are present.
The journals have been scanned with a SupraScan 10000RGB scanner; 24-bit true colour, 400 dpi, saved in TIFF-format. Copies of the master images have been converted to Black & White, 1-bitmap images and OCRed with ABBYY Fine Reader v.9 software. Adobe Acrobat v.9 was used for the merging and conversion to the final presentation PDF-format.
