NOTE ON PAGE 248. 



To obviate misapprehension, it is necessary to observe, that the number of* elapsed 

 years of the Saca era subjoined to A'ryabhatta's computation of past time, is an 

 addition by the scholiast of Bra h meg upta, in course of comparing elapsed time, 

 as reckoned by the two authors. For the passage, which he twice quotes from the 

 Dasa-giticd of Aryabhatta, reckons from the beginning of the Calpa to the 

 Bharata, which is the era of Yudhishfhira, and the epoch employed by him, without 

 any notice either of Saca or Sambat. 



NOTE to an ESSAY on the CAMPHOR TREE of SUMATRA; by 



H. T. C. late President. 



Since my return to England, I have had the opportunity, by the indulgence of 

 Sir Joseph Banks, to inspect the specimen in his collection from which the 

 younger Gcertner, to whom it was communicated, described his Dryobalanops 

 aromatica ; and I find that the leaves entirely agree, and that it is unquestionably 

 the same species with the Camphor tree of Sumatra. This information actually 

 accompanied the specimen seen by Dr. C. F. Gcertner, though he have inad- 

 vertently referred it to Ceylon for a habitation, and as erroneously alleged, that 

 the bark of the tree is cinnamon. 



The fruit has been also figured and described by M. Corre'a de Serra, (Ann, 

 du Mus. d'Hist. nat. 10. 159,) under the name of Pterygium teres; equally without 

 any intimation of the tree affording the Sumatran camphor. 



As the Pterygium costatum of the same author is the Dipterocarpus costatus of 

 the younger Gcertner, whose publication on both that and the Dryobalanops 

 preceded by a year the earliest of Corre'a de Serra's concerning these fruits, it 

 is presumed, that Gcertner's names of both genera will be retained. Whether 

 his name of the species now in question shall also be preserved, others must 

 determine. It is, however, to be remarked, that the name, which Mas given to it 

 in India, before the identity of species could be ascertained, is the most appropriate.
