Who would think, then, that such fine ladies and gentlemen should regale themselves with an essence found in the inglorious bowels of a sick whale! Yet so it is. By some, ambergris is supposed to be the cause, and by others the effect, of the dyspepsia in the whale. How to cure such a dyspepsia it were hard to say, unless by administering three or four boat loads of Brandreth’s pills, and then running out of harm’s way, as laborers do in blasting rocks.
