This Morning Mr. Laurens called upon me to introduce to me a West India Gentleman from Jamaica, a Mr. 
Mr. Laurens says the English are convinced that the Method of coppering Ships is hurtfull. The Copper corrodes all the Iron, all the Bolts, Spikes and Nails, which it touches.

L'Esprit, et beaucoup de Tête aussi.—Jay answered, Ouy Monsieur, Monsieur Adams a beaucoup D'Esprit.4
