397 페이지 - ... noisome effluvia ; during its continuance the fish float quite helpless on the turbid surface, and are easily taken. These rapid changes (as capricious in their nature as those of the Euripus), generally continue from thirty minutes to upwards of two hours ; and are succeeded by a breeze from the southward, which quickly increases to heavy gusts.

97 페이지 - A piece of zinc as large as a pea, or the point of a small iron nail, were found fully adequate to preserve forty or fifty square inches of copper ; and this, wherever it was placed, whether at the top, bottom, or in the middle of the sheet of copper, and whether the copper was straight or bent, or made into coils.

The blindness was first observed, as before, in looking at the face of a person I met, whose left eye was to my sight obliterated.
