MINOR QUERIES.
Medical Symbols.—"A PATIENT" inquires respecting the origin and date of the marks used to designate weights in medical prescriptions.
Charles II. and Lord R.'s Daughter.—Can any of your readers inform me who was the lady that is referred to in the following passage, from Henry Sidney's Diary, edited by Mr. Blencowe (March 9. 1610, vol. i. p. 298.):—
"The King hath a new mistress, Lord R——'s daughter: she brought the Duke of Monmouth to the King."
C.
St. Alban's Day.—A friend has asked me the following question, which some of your readers may perhaps be able to answer, viz.:—
"Till the reign of Ed. VI. St. Alban's Day was kept in England on June 22d (the supposed anniversary of his martyrdom). It was then erased from the kalendar, but restored to it in the reign of Chas. II.; when it was transferred to June 17th. Why was this change made?"

Black Broth (No. 19. p. 300.).—If this were a sauce or condiment, may not the colour have been produced by the juice of the Boletus, much used in Greece to the present day?
