There were specimens of articles in Liverpool, which I entirely overlooked at Bristol, and which I believed I should have overlooked here also, had it not been for seeing them at a window in a shop; I mean those of different iron instruments used in this cruel traffic. I bought a pair of the iron hand-cuffs with which the men-slaves are confined. The right-hand wrist of one, and the left of another, are almost brought into contact by these, and fastened together, as the figure A in the annexed plate represents, by a little bolt with a small padlock at the end of it. [Illustration: Handcuffs] I bought also a pair of shackles for the legs. These are represented by the figure B. The right ancle of one man is fastened to the left of another, as the reader will observe, by similar means. I bought these, not because it was difficult to conceive how the unhappy victims of this execrable trade were confined, but to show the fact that they were so. For what was the inference from it, but that they did not leave their own country willingly; that, when they were in the holds of the slave-vessels, they were not in the Elysium which had been represented; and that there was a fear either that they would make their escape, or punish their oppressors? [Illustration: Shackles for the legs] I bought also a thumb-screw at this shop. The thumbs are put into this instrument through the two circular holes at the top of it. By turning a key, a bar rises up by means of a screw from C to D, and the pressure upon them becomes painful. By turning it further you may make the blood start from the ends of them. By taking the key away, as at E, you leave the tortured person in agony, without any means of extricating himself, or of being extricated by others. This screw, as I was then informed, was applied by way of punishment, in case of obstinacy in the slaves, or for any other reputed offence, at the discretion of the captain. At the same place I bought another instrument which I saw. It was called a speculum oris. The dotted lines in the figure on the right hand of the screw represent it when shut, the black lines when open. It is opened, as at G H, by a screw below with a nob at the end of it. This instrument is known among surgeons, having been invented to assist them in wrenching open the mouth as in the case of a locked jaw; but it had got into use in this trade. [Illustration: Thumb screw] [Illustration: Speculum oris] On asking the seller of the instruments on what occasion it was used there, he replied that the slaves were frequently so sulky as to shut their mouths against all sustenance, and this with a determination to die; and that it was necessary their mouths should be forced open to throw in nutriment, that they who had purchased them might incur no loss by their death.
