This question is inspired from: Why do we call salts such as AgCl sparingly soluble?
The extent of solubility can be expressed as descriptive terms. U.S. Pharmacopoeia has made the following classification according to the mass msv of solvent required to dissolve one unit of mass msu of solute (Here solvent is water at 20-25 °C.):

Here "Sparingly soluble" is different than "Slightly Soluble" and is used to describe compounds that are not totally insoluble. Since when was the term "Sparingly Soluble" first introduced in chemistry and by who? Was this term introduced when the first solubility classification was generalized or was it introduced at a later point of time because they found that an extra term is needed to differentiate "Slightly Soluble" and this?
