[ William Hamilton Gibson, American illustrator and naturalist. ] Autograph Letter Signed ('W Hamilton Gibson') to 'Mr Skinner', thanking him for a notice of a lecture

3pp., 12mo. Bifolium. In good condition, on lightly-aged paper. He thanks him for a notice of his lecture which is 'sympathetic and in every way adequate and helpful'. He is accustomed to reviews 'which however kindly and appreciative have nevertheless so woefully manipulated my facts'. He gives as an example his 'good friend Baker of the Union', who 'in the kindliest & most cordial spirit put words in my mouth, statements of scientific fact [...] But it is as you have so often told me. The only way to establish a truth is to pound away at it, iteration and reiteration.'
