The crew of the man of war sleep on the deck which is next under the gun deck, while our destination was on the deck under that. It was to the ship what the cellar is to a house. It was under water, and of course, without windows, or air holes. All the air and light came through the hatch way, a sort of trap door or cellar way. In this floating dungeon, we miserable young men spent our first night, in sleepless anguish, embittered with the apprehension of our suffering cruel death by suffocation. Here the black hole of Calcutta rose to my view in all its horrors; and the very thought stopped my respiration, and set my brain on fire. In my distress, I stamped with my feet, and beat my head against the side of the ship in the madness of despair. I measured the misery of those around me by what I myself suffered. Shut up in the dark with ninety-nine distressed young men, like so many galley slaves, or Guinea negroes, excluded from the benefit of the common air, without one ray of light or comfort, and without a single word expressive of compassion from any officer of the ship. I never was so near sinking into despair. We naturally cling to life, but now I should have welcomed death. To be confined, and even chained any where in the light of the sun, is a distressing thing, especially to very young men, but to be crowded into a dirty hole in the dark, where there was no circulation of air is beyond expression horrible. Perhaps my study of the human frame, and my knowledge of the vital property of the air, and of the philosophy of the vital functions, may have added to my distress. I remembered what I had read and learnt in the course of my education, viz: that every full grown person requires _forty-eight thousand_ cubic inches of air in an hour, or _one million, one hundred and fifty-two thousand_ cubic inches in the course of a day; and that if this is once received into the lungs and breathed out again, it cannot be breathed a second time, till it is mixed with the common atmospheric air. When I considered that our number amounted to an hundred, I could not drive from my mind this calculation, and the result of it nearly deprived me of my reason. The horrors of the _Black Hole of Calcutta_ have been long celebrated, because _Englishmen_ suffered and perished in it. Now the English have more than a _thousand_ black holes into which they unfeelingly thrust their impressed men, and their prisoners of war. Their tenders that lay in the Thames, off Tower-wharf, are so many _black holes_ into which they thrust their own people, whom their press gangs seize in the streets of London, and crowd into them like so many live rabbits or chickens carrying in a cart to market. My reflections on these things have greatly changed my opinion of the English character in point of humanity.
