APPENDIX. 331 



No. II. 



The foUowing pages contain abstracts of tte meridian 

 distances measured in H.M. Surveying Ship " Rattle- 

 snake" and her tender the "Bramble," in the survey of 

 the Inner Route through Torres Strait, the Louisiade 

 Archipelago, and the S. E. Coast of New Guinea, during 

 the years 1847-8-9 and 50, under the command of the 

 late Captain Owen Stanley, R.N., F.R.S. 



The 1st three columns require no explanation. 



The 4th (interval of days) is the elapsed time between 



the last day at the first station and first day at the second. 



The 7th (meridian distance in arc) is the result of the 



particular measurement specified between the two places 



named. 



The 8th (mean meridian distance from Sydney) is that 

 deduced by a mean value of two or more distances by the 

 same T. K.'s, and in some instances of one only, in some 

 of the principal stations connected with the survey. 



The times throughout these abstracts have been deter- 

 mined by equal altitudes of the sun, excepting in those 

 instances where the contrary is specified by A.A. The 

 interpolations in the " Rattlesnake's" distances have been 

 calculated by Owen's method : those of the " Bramble" 

 by a method of Lieut. Yule's. 



In the " Rattlesnake's'' distances interpolation has been 

 employed throughout ; in the " Bramble's" only where an 

 intermediate distance is measured between two rates. 



The asterisks point out the place to which the mean 

 meridian from Sydney refers.
