Variations in the Crystallisation of Potassium Hydrogen Succinate due to the presence of other metallic compounds in the Solution

Extract

In the summer of 1902, while working as a student in the Chemistry Department of Edinburgh University, I prepared a quantity of potassium chromoxalate (Gregory's salt) as an ordinary exercise, and this led me to attempt the preparation of a similar derivative of succinic acid, since such derivatives apparently had not been obtained.
