Hence the mean height of the fides is about lo inches, and the greateft 
height fcarcely exceeds one foot, in the middle of this wide-extended 
ocean ; which falls far Ihort of what might have been expeded from phy- 
fical principles. The caufe of this remarkable differenee deferves farther 
inquiry. The time of high water alfo appears to precede the moon’s 
pairing the meridian by 45 minutes at a medium, and the time of low 
water to precede the fame, by 6*' 31'. But the mean difference of high 
and low water, Ihould be 6'’ 12 ', which fubtraded from b** 31’, leaves 
o'’ 19^ by which the time of high water fliould precede the moon’s 
pairing the meridian ; the mean of this and o'* 45' is 32', by which the 
time of high water precedes the moon’s palling the meridian, by a 
medium of all the obfervations. The times of high and and low water 
feern to be fubjed to great irregularity on particular days ; no dou-bt 
owing to the fmall rife of the water, and the fmallnefs of its force in 
confequence, which renders it more liable to be difturbed by the adion 
of the winds and other caufes ; part of the irregularity may be attributed 
to the difficulty ot obfervmg the time of the liocd or ebb, with any 
degree of certaimy. N. M. 
N. B. The llland here named King George’s Wand, is called by the 
natives Ota-hcite, by which name it wiil henceforth be calkd, the name 
of K. (leorge’s Wand having been given before to another ifland in lar. 
148. difcovered by Commodoie Byron. 
Mr. Green ha-ing died at fea in the palTage home from Batavia, 
all the altronpmical and other obfervations were partly arranged by Capr. 
Cock, and partly ty the Aftronomer Koyal, from the original manufeript-, 
and calculated by the latter. Real
