, the Examiner of Sea Journals for the English East India Company,whilst translating some Spanish documents captured in the Philippines in 1752, found de Torres's testimony. This discovery led Dalrymple to publish the Historical Collection of the Several Voyages and Discoveries in the South Pacific Ocean in 1770-1771. Dalrymple presented a beguiling tableau of the Terra Australis, or Southern Continent:

The number of inhabitants in the Southern Continent is probably more than 50 millions, considering the extent, from the eastern part discovered by Juan Fernandez, to the western coast seen by Tasman, is about 100 deg. of longitude, which in the latitude of 40 deg. amounts to 4596 geographic, or 5323 stature miles. This is a greater extent than the whole civilized part of Asia, from Turkey to the eastern extremity of China. There is at present no trade from Europe thither, though the scraps from this table would be sufficient to maintain the power, dominion, and sovereignty of Britain, by employing all its manufacturers and ships. Whoever considers the Peruvian empire, where arts and industry flourished under one of the wisest systems of government, which was founded by a stranger, must have very sanguine expectations of the southern continent, from whence it is more than probable Mango Capac, the first Inca, was derived, and must be convinced that the country, from whence Mango Capac introduced the comforts of civilized life, cannot fail of amply rewarding the fortunate people who shall bestow letters instead of quippos (quipus), and iron in place of more awkward substitutes.

The cartographic depictions of the southern continent in the 16th and early 17th centuries, as might be expected for a concept based on such abundant conjecture and minimal data, varied wildly from map to map; in general, the continent shrank as potential locations were reinterpreted.

in which he wrote:
"There is no probability, that any other detached body of land, of nearly equal extent, will ever be found in a more southern latitude; the name Terra Australis will, therefore, remain descriptive of the geographical importance of this country, and of its situation on the globe: it has antiquity to recommend it; and, having no reference to either of the two claiming nations, appears to be less objectionable than any other which could have been selected.*"
