and Miscellaneous Particulars. 
Lewis observes, that mint is said to prevent the coagulation of milk ; and hence it has been recommended 
to be used with milk diets, and even in cataplasms and fomentations for resolving coagulated milk in the 
breasts : upon experiment, the curd of milk, digested in a strong infusion of mint, could not be perceived to 
be any otherwise affected than by common water; but milk, in which mint leaves were set to macerate, did 
not coagulate near so soon as an equal quantity of the same milk kept by itself. Dry mint digested in rectified 
spirits of wine, gives out a tincture which appears by day-light of a fine dark green, but by candle-light of a 
bright red color. The fact is, that a small quantity of this tincture is green, either by day-light or candle- 
light, but a large quantity seems impervious to common day-light ; however, when held between the eye and 
a candle, or between the eye and the sun, it appears red ; so that if put into a flat bottle it appears green, 
but when viewed edgewise red. 
For medicinal use spearmint is generally cut just as the flowers appear; but for obtaining the essential 
oil> the flowering plant is preferred. It should be cut in very dry weather. [London Dispensatory, 384.) 
M. piperita has a more penetrating smell than any of the other species, and a much stronger taste, pungent 
and glov.'ing like pepper, sinking as it where into the tongue, and followed by a sensation of coldness. Its 
stomachic, anti-spasmodic and carminative qualities render it useful in flatulent colics, hysterical affections, 
r«chings, and other dyspeptic symptoms, acting as a cordial, and often producing immediate relief. The 
officinal preparations are an essential oil, a simple water, and a spirit. The essence of peppermint is an 
elegant medicine, and seems to be the rectified oil dissolved in spirits of wine. 
" The cultivators of the plant observe, that to keep up its quality, the roots must be transplanted every llueu
