prisoner. The lord-mayor, however, discharged Strong, as he had been taken
up without a warrant.

As soon as this determination was made known, the parties began to move
off. Captain Laird, however, who kept close to Strong, laid hold of him
before he had quitted the room, and said aloud, "Then I now seize him as my
slave." Upon this, Mr. Sharp put his hand upon Laird's shoulder, and
pronounced these words: "I charge you, in the name of the king, with an
assault upon the person of Jonathan Strong, and all these are my
witnesses." Laird was greatly intimidated by this charge, made in the
presence of the lord-mayor and others, and, fearing a prosecution, let his
prisoner go, leaving him to be conveyed away by Mr. Sharp.

Mr. Sharp, having been greatly affected by this case, and foreseeing how
much he might be engaged in others of a similar nature, thought it time
that the law of the land should be known upon this subject. He applied
therefore to Doctor Blackstone, afterwards Judge Blackstone, for his
opinion upon it. He was, however, not satisfied with it, when he received
it; nor could he obtain any satisfactory answer from several other lawyers,
to whom he afterwards applied. The truth is, that the opinion of York and
Talbot, which had been made public and acted upon by the planters,
merchants, and others, was considered of high authority, and scarcely any
one dared to question the legality of it. In this situation, Mr. Sharp saw
no means of help but in his own industry, and he determined immediately to
give up two or three years to the study of the English law, that he might

these studies was the publication of a book in the year 1769, which he
called "A Representation of the Injustice and dangerous Tendency of
Tolerating Slavery in England." In this work he refuted, in the clearest
manner, the opinion of York and Talbot. He produced against it the opinion
