THE same manner is followed if any man be slain, for straight the murderer is pursued of every man till he be taken. So soon as any is brought to the Justices of peace by this hue or cry, by the Constable or any other who doth pursue the malefactor, he doeth examine the malefactor, and writeth the examination and his confession: then he doth bind the party that is robbed or him that sueth, and the Constable, and so many as can give evidence against the malefactor to be at the next sessions of gaol delivery to give evidence for the Queen. He bindeth them in recognisance of x.l’, xx.l’, xxx.l’, xl.l’, or C.l’, according to his discretion,* and the qualities of the crime: which certified under his hand, is levied upon the recognisance* if they fail of being there.
