Note. — The above numbers were taken from the record, converting the fathoms into feet and deducting 8, in 

 order to reduce the mean level of 15 feet to the adopted C iparison of 7 feet. The observatioi 



taken with the sounding line ; bottom weedy. 



Sept. 8. Some doubt about the time between 1 and 5 P. M. 



After October 22 the foundings are too irregular, and Later oh srvations with the pulley-gauge too mucli 

 affected by changes of the index. 



Thin last series is considerably inferior in accuracy to the three precedin ; .cries.
