JOHN HARRISON. From a mezzotint by Tassaert, published in 1768, after a painting by King. A copy of this painting is exhibited in the Science Museum, South Kensington. The machine behind Harrison is his No. 3 (drawn too large), and that at his right hand No. 4. See p. 41, f. --Note. This type of wig was called a “Garrick cut”, having been introduced by the famous actor. [B]
