[Various particulars of the prolonged and perplexed navigation ensuing here follow, with incidents of a calamitous calm, from which portion one passage is extracted, to wit:] —That on the fifth day of the calm, all on board suffering much from the heat, and want of water, and five having died in fits, and mad, the n*****s became irritable, and for a chance gesture, which they deemed suspicious—though it was harmless—made by the mate, Raneds, to the deponent in the act of handing a quadrant, they killed him; but that for this they afterwards were sorry, the mate being the only remaining navigator on board, except the deponent. * * * * *
