measurement thereof may be considered as correct if taken at 

 892 feet. The ascent and descent, including the passage of the 

 river, occupied nearly two hours. The period when our party 

 visited the falls was in the month of January, when there was 

 sufficient water to enable us to approach to the brink, and a 

 better period, in our estimation, than in the monsoon, when the 

 river is so full that the separate falls cannot be seen, the water 

 rushing over in one vast sheet, which may be more terrific, but 

 has the disadvantage of not permitting a near approach to the 

 brink, or a descent into the basin. The journey to the falls of 

 Girsupah may easily be effected from any part of the western 

 coast, as the traveller can be landed at Ibonore by pattismas, 

 i. e. native boats, from which he can proceed by the river as far 

 as Girsupha (16 miles), at which there is a bungalow, and from 

 thence ascend the pass AUawallah, and thence to the falls, dis- 

 tant 6 miles. The scenery in the pass is interesting to those 

 fond of the picturesque.

10. Inflammation of the Fraxinella (Dktamnus alba.) — 

 Among, the physical phenomena which are produced during 

 vegetable life, phenomena which might become a subject of 

 curious study, there are few whose development appears more 

 surprising than that which is generally attributed to the fraxi- 

 nella, viz., that of being surrounded in hot days with a sort of 

 etherial atmosphere, which can be ignited by the application of 

 a taper without injuring the plant. Such a phenomenon, in fact,
