 been made, in apparent time; the other columns show the results, viz. the 4th 

 column contains the true conjunction in apparent time; the oth column cor>- 

 tains the latitude of the moon, which, as it depends on the manner of observing 

 the 1 phases, is subject to some variety; the 6th or last column contains the 

 difference between the various meridians and that of Greenwich.

F'll. Of a Bituminous Lake or Plain in the Island of Trinidad. By Mr. Alex, 



Anderson, p. 63. 

 A most remarkable production of nature in the island of Trinidad, is a bitu- 

 minous lake, or rather plain, known by the name of Tar Lake ; by the French 

 called La Bray, from the resemblance to, and answering the intention of, ship 

 pitch. It lies in the leeward side of the island, about half way from the Bocas 

 to the south end, where the Mangrove swamps are interrupted by the sand-banks 

 and hills ; and on a point of land which extends into the sea about 2 miles 

 exactly opposite to the high mountains of Paria, on the north side of the Gulf. 

 This cape, or head-land, is about 50 feet above the level of the sea, and is the 

 greatest elevation of land on this side of the island. From the sea it appears a 

 mass of black vitrified rocks ; but on a close examination it is found a composi- 

 tion of bituminous scoriae, vitrified sand, and earth, cemented together ; in 

 some parts beds of cinders only are found. In approaching this Cape, there is
