but not having seen either it's fruit, or it's 

 flowers, we are ignorant whether it be the piritu 

 palm-tree of the Caribbees, or the cocos acu- 

 leata of Jacquin. 



The rock on this road presents a geological 

 phenomenon so much the more remarkable, as 

 the existence of a real stratified granite has been 

 long disputed. Between La Trinchera and the 

 inn of Camburya coarse-grained granite appears, 

 which the disposition of the spangles of mica, 

 collected in small groups, scarcely admits of 

 confounding with the gneiss, or with rocks of a 

 schistose texture. This granite, divided into 

 ledges of two or three feet thick, is directed N. 

 52° E., and slopes to the North-West regularly 

 under angles of 30° or 40°. The feld-spar, crys- 

 tallized in prisms with four unequal sides, and 

 an inch long, passes through all the tints from a 

 flesh red to yellowish white. The niica united 

 in hexagonal plates, is black, and sometimes 

 green. The quartz predominates in jthe mass ; 

 and is generally of a milky white. I observed 

 neither hornblende, nor black schorl, nor rutile 

 titanite, in this granite. In some ledges we 

 recognised round masses, of a blackish gray ? 

 very quartzose, and almost destitute of mica. 

 They are from one to two inches diameter ; and 

 are found in every zone, in all granitic moun- 

 tains. These are not imbedded fragments, as 

 at GreifFenstein in Saxony, but aggregations of
