Upon the Authority of this Table we need not fear the Success of any Equinoctial Plant, in the Latitude of Jamaica.
It does not appear that there is any vegetable production under the Line, that requires a hotter Climate, to arrive at the last Stage of Maturity, than what subsists in the Latitude of 17 Degrees. Our accounts of the comparative heat of different Climates are still very defective, especially of those within the Tropicks; But from such as has been given, it appears that the difference between the heat of Jamaica and of the Places under the Line, is very inconsiderable, and incapable to prevent the arrival of the Equinoctial Plant, at its utmost perfection in that Island.
The Plants of any Country under the Equator, are almost the same with those of a Country 16 or 18 Degrees from it under the same Meridian. The Plants of Java and Sumatra are an Instance of this. For tho' under the Equator they are almost the same with those of Ceylon, and and of the Malabar and Coromandel Coasts, which lie in the same Latitude, and even further North than Jamaica. Many Plants which are Natives under the Equator in America have from thence been translated, and do now thrive luxuriantly in that Island, and we know of no reason why those from under the Equinoctial in Asia may not be translated with equal Success.
Upon the Authority of these Arguments we might translate to Jamaica
