In a recent paper published by the authors, some measurements of the viscosity of aqueous solutions indicated that it would be of interest to investigate more fully the viscosity of solutions, especially those which exhibit what is now generally known as “negative viscosity,” over a wider range of temperature.
This has now been done to a certain extent, and to enable a comparison to be made between electrolytes and non-electrolytes in aqueous solution, some other substances have been included in the investigation. They are:—potassium chloride, potassium chlorate, ammonium iodide, potassium ferricyanide, potassium ferrocyanide; mercuric chloride, mercuric cyanide; carbamide.

The apparatus was made for us by J. Ednie, mechianic in the Physiology Department, Edinburgh University.]
