PROP. VI. By calculations, such as they are, our author finds, that, upon an average of 66 years, from 1690 to 1756, this number of 8000 have been annually lost, that is, have died abroad in the colonies, in war, or on the account of navigation. PROP. VII. That, since the inhabitants of Britain and Ireland are about 8,000,000, and that the augmentation is annually about 8000, we may conclude in general for all Europe, that, for every million of inhabitants, there is an annual augmentation of 1000; consequently, every thousand men slain in war must destroy all the augmentation of a million of inhabitants during a year. Consequently France, which contains 14 millions, according to Sir William Petty, having lost above 14,000 men a-year, during the same 66 years, cannot have augmented in population. PROP. VIII. That the progress of trade and navigation augmenting the loss of people by sea, must consequently have diminished population over all Europe. PROP. IX. The exportation of our corn proves what the above propositions have demonstrated. For supposing the progress of agriculture to compensate the additional quantity distilled of late years, there is still 1⁄6 of the crop exported, which proves that our numbers are small, and that they do not augment. From these propositions our author concludes, that what stops multiplication in the British isles is, 1st, That living in celibacy is become a-la-mode: 2dly, That wars have been carried on beyond the nation’s force: 3dly, That the use of spirituous liquors destroys great numbers of inhabitants. I shall now shortly apply the principles I have been laying down, in order to resolve every phenomenon here described, as to the population of Great Britain. These I shall willingly take for granted, as it is of no consequence to my reasoning, whether they be exact or not: it is enough that they may be so; and the question here is only to account for them.
