LENTIGINES, spots of a yellowish colour, of the bigness of a lentile seed, scattered over the face, neck, and hands. Freckles are either natural, or proceeding accidentally from the jaundice or the action of the sun upon the part. Heat or a sudden change of the weather, will often cause the skin to appear of a darker colour than natural; and thereby produce what is called tan, fumburn, and morphew, which seem to differ only in degree; and usually disappear in winter.

Persons of a fine complexion, and whose hair is red, are the most subject to freckles, especially in those parts which they expose to the air.

To remove freckles, put juice of lemons in a glass phial, and mixing it with sugar and borax finely powdered, let it digest eight days, and then use it. Homberg proposes bullocks gall mixed with alum, and, after the alum has precipitated, exposed three or four months to the sun in a clothe phial, as one of the best remedies known for the removing of freckles.
