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 ÆäÀÌÁö - 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. And where the connection between...
184 ÆäÀÌÁö - A thick glass, though as much or more permeable to light than a thin glass of worse quality, allows a much smaller quantity of radiant heat to pass.
295 ÆäÀÌÁö - In this instance the loss of sight was toward my left, and was the same whether I looked with the right eye or the left. This blindness was not so complete as to amount to absolute blackness, but was a shaded darkness without definite outline. The complaint was of short duration, and in about a quarter of an hour might be said to be wholly gone, having receded with a gradual motion from the centre of vision obliquely upwards towards the left.

However, it is always better to make the conductor so large as not to be destroyed by the stroke ; and the only motive for substituting a wire for a stout bar is the saving in point of expense. The noise of the thunder generally occasions much alarm, although the danger is then...

The whole was plunged under sea water; the copper remained perfectly polished. The same experiment was made with iron ; and now, after a lapse of a month, in both instances, the copper is as bright as when it was first introduced, whilst similar pieces of copper, undefended, in the same...
296 ÆäÀÌÁö - ... affection occurred again to myself, without my being able to assign any cause. whatever, or to connect it with any previous or subsequent indisposition. 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. My blindness was in this instance the reverse of the former, being to my right (instead of the left) of the spot to which my eyes were directed ; so that I have no reason to suppose it in any manner connected with...
