Subjoined is a table giving the absolute viscosity of various gums. A

comparison of the uncorrected viscosities with the corrected shows the

great importance of Slotte's correction for dextrins and inferior gum

arabics; in other words, for solutions of low viscosity, while it will

be observed to have little influence upon the uncorrected [eta] obtained

for the Ghatti gums and the best samples of gum arabic.
