1841.] the Tides in the Indian Archipelago. 313 



During these months, when at new and full moon short tides 

 were running, the high water generally came in about 6h. 50m. in the 

 morning, and at about 7h. 10m. in the evening. However, these numbers 

 cannot exhibit a mean number, nor give a direction to calculate the 

 high water of the other days, although the time of the flood tide, however 

 irregular, seems daily to come in later, being retarded twelve hours in 

 a fortnight, while this time on the appearance of the short tides has a 

 most irregular course. 



The natives foretell sometimes very exactly the return of the small 

 and the short tides. 



The greatest rise and fall was, ... ... 4* 26 ebb. 



The smallest, 0* 07 



The mean, 2- 17 



The greatest difference between highland low water was at full moon 

 in December, in June, and May, and in general when the monsoons 

 had passed ; while the difference during the months, while the monsoons 

 changed, was less perceptible. 



The greatest rises and falls often took place at new and full moon, 

 though by no means always. 



The highest water-mark was also observed when the monsoons were 

 i in their full force. Besides it deserves notice, that during the period 

 when flood and ebb tide came in only once a day, that is during the 

 common long tides, the rises and falls following each other successively 

 increase and decrease ; while when two tides or middle tides occur in 

 a day, the succeeding rises are alternately great and small, and thus 

 also the falls, while the difference in the quantum of two succeeding 

 rises, probably depends on the decrease of the moon. 



At Corimon, Java. 



An ebb and flood tide is here even less perceptible than at other 

 stations. It appears, however, from the observations that were made, 

 that here, as at Klampsis on the North coast of Madura, the stream runs 

 especially with the rising water to the East, and with the falling water 

 to the West ; in the East monsoon in the night, in the West monsoon in 

 the day time.
