Summary

Everything in Wallace’s sketch also appears in CD’s sketch of 1844. A year ago CD sent a short sketch of his views to Asa Gray. Can CD honourably publish his sketch now that Wallace has sent outline of his views? "I would far rather burn my whole book than that he or any man shd. think that I had behaved in a paltry spirit." Does not believe Wallace originated his views from anything CD wrote to him.
