I. — Astronomic Observations. 



Kaiho. — Latitude determined by a circuiumeridiau altitude going and four 

 returning (Obs. Nos. 18, 91, 92, 93, and 94); longitude results from two series 

 of altitudes on return (Obs. Nos. 95 and 96) : 



Butiti. — Using the latitude estimated at 0^0° 39' 30", the longitude is 

 obtained by two series of altitudes observed on the return (Obs. Nos. 89 and 90) : 



1st August \ = 2^2™34'^-3 E.G. 



1st „ = 2 2 34-8 „ 



Butiti X = 2^ 2'" 37^-5 



„ = 30° 38' 37" 



Ihnoona. — With the approximate value \ = 2'' 1"^ 17^ East Greenwich, the 

 latitude is calculated by a meridian altitude observed on going (Obs. No. 24) : 

 , 1st June.— Duwona 0=0° 33' 25" N. 



IhitanuÌM. — Latitude determined on the return 1)y a meridian altitude 

 (Obs. No. 70) ; and longitude l)y two series of altitudes (Obs. Nos. 71 and 72) : 



20th July = 0° 26' 33" N. ... x = 2'M'"4^-l E.G. 



i^Oth „ „ = 2 1 4-6 „ 



Butanuka = 0° 26' 33" N. ... x = 2'M™4^-4 



„ = 30M6'6" 



y>/A/(//f/f?.— Longitude ol)taincd by two series of altitudes on going, using 

 0=0° 20' 20" N. ol)tained from the maps (01)s. Nos. 30 and 31) : 



4th June A = 2'' 0'" 27^-0 E.G. 



= 20 27-2 



Xakiiawa. — Obtaining from the maps the latitude = 0° 20' 20" N., the 

 longitude was had l)y a single series of altitudes at the artificial horizon 

 without roof (Obs. No. 61) : 



Nakitawa X = 2" 0"' 19^-6 E.G. 



„ = 30° 4' 54" „ 



321 Y
