8.  That the loss of the newly-imported slaves, within the three first years after their importation, bore a large proportion to the whole number imported.

9.  That the natural increase of population among the slaves in the islands appeared to have been impeded principally by the following causes:—­First, by the inequality of the sexes in the importations from Africa.  Secondly, by the general dissoluteness of manners among the slaves, and the want of proper regulations for the encouragement of marriages, and of rearing children among them.  Thirdly, by the particular diseases which were prevalent among them, and which were, in some instances, to be attributed to too severe labour, or rigorous treatment; and in others to insufficient or improper food.  Fourthly, by those diseases, which affected a large proportion of negro-children in their infancy, and by those to which the negroes, newly imported from Africa, had been found to be particularly liable.

10.  That the whole number of the slaves in the island of Jamaica, in 1768, was about 167,000, in 1774, about 193,000, and in 1787, about 256,000:  that by comparing these numbers with the numbers imported and retained in the said island during all these years, and making proper allowances, the annual excess of deaths above births was in the proportion of about seven-eighths per cent.; that in the first six years of this period it was in the proportion of rather more than one on every hundred; that in the last thirteen years of the same it was in the proportion of about three-fifths on every hundred; and that a number of slaves, amounting to fifteen thousand, perished during the latter period, in consequence of repeated hurricanes, and of the want of foreign supplies of provisions.

11.  That the whole number of slaves in the island of Barbados was, in the year, 1764, about 70,706; in 1774, about 74,874; in 1780, about 68,270; in 1781, after the hurricane, about 63,248, and in 1786, about 62,115; that, by comparing these numbers with the number imported into this island, (not allowing for any re-exportation,) the annual excess of deaths above births in the ten years, from 1764 to 1774, was in, the proportion of about five on every hundred; that in the seven years, from 1774 to 1780, it was in the proportion of about one and one-third on every hundred; that between the years 1780 and 1781 there had been a decrease in the number of slaves, of about 5000; that in the six years, from 1781 to 1786, the excess of deaths was in the proportion of rather less than seven-eighths on every hundred; that in the four years, from, 1783 to 1786, it was in the proportion of rather less than one-third on every hundred; and that during the whole period, there was no doubt that some had been exported from the island, but considerably more in the first part of this period than in the last.
