184 i.J the Tides in the Indian Archipelago. 31 1 



In the latter days of August, the number of days when the short 

 tide comes in, it increases so that almost the whole month, as well as in 

 September, two tides took place in the same days, though of a very irre- 

 gular duration ; then the number of days when the short tides were 

 observed again decreased, occurring only twice or thrice in the month ; 

 till in December long tides almost always return, so that in this month 

 there is only one ebb tide each day. 



However, supposing in January and February the short tides have 

 been overlooked, which is not impossible, as the character of these 

 was not known at the commencement of the observations, or we should 

 be able to assign a reason, that in July and December long tides, and 

 in September and February short tides take place, as well as between 

 these months, the number of days when short tides obtain, decreases and 

 increases ; something similar to this has been observed at Fagol ; but 

 the period of long and short tides does not correspond. 



There is no peculiarity concerning the difference of the succeeding 

 tides ; but we must not omit to notice, that there, as well as at Klampsis, 

 in December, January, and February, flood tide always comes in before 

 noon, and this period is successively retarded ; the flood tide being ob- 

 served during May in the night ; during June in the evening ; during 

 July and August in the afternoon ; in September before and after noon ; 

 in October and November in those days where only one tide in one day 

 took place before noon. It is evident from these facts, that during the 

 East monsoon the flood-tide comes in the afternoon, and in the 

 evening ; while during the West monsoon it was before noon, and in 

 the morning just the reverse of what has been observed at Klampsis. 



The period of the flood tide at new and full moon, however irregu- 

 lar it may be in the interval between them, is always about ten o'clock, 

 (or between 9h. 30m. and lOh. 45m.) p. m. from March to December, 

 that is in the East monsoon ; and at a. m. from September to March 

 in the West monsoon, a singular correspondence with the observations 

 at Klampsis. It is evident that on account of the regularity of the 

 tides, this period cannot be used as a mean number, to calculate the 

 period of the flood tide for other days. 



The mean rise and fall was, ... ... 0- 67 ebb. 



The greatest, 1-32 



The smallest, 0-02
