I. — Astronomic Observations. 



Kaiho. — Latitude determined by ;i circummeridiiui 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) : 



27th May = 0° 29' 56" N. 



2nd August „ = 30 36 „ ... ,\ = 2" S" 7«- 8 E.G. 



2nd „ „..0 30 09 „ ... „ = 2 3 7-9 „ 



2nd „ „ = 29 26 „ 



2nd ;, „ = 30 U „ 



Kaibo = 0° 30' 4" N . ... \ = 2'" 3"" 7"- 9 E.G. 



,, = 30° 46' .58" „ 



Bniiti. — Using the latitude estimated at = 39' 30 ", the longitude is 

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



1st Atigust \ = 2" 2"" 34»- 3 E.G. 



l«t „ „ = 2 2 34-8 „ 



Butiti \ = 2" 2"" 37"- 5 



„ = 30° 38' 37" 



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

 latitude is calculated by a meridian altitude observed on going (01)s. No. 24) : 

 1st June.— Dmvona 0=0° 33' 25" N. 



Bu/aniika. — Latitude determined on the return liy a meridian altitude 

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



20th July = 0° 26' 33" N. ... \ = 2M"'4»-1 E.G. 



20th „ „ = 2 14-6 „ 



Butanuka = 0° 26' 33" N. ... X = 2'> 1"" 4''-4 „ 



,, = 30° 16' 6" „ 



Bikmujn. — Longitude oljtained by two series of altitudes on going, using 

 0=0° 20' 20" N. obtained from the maps (Obs. Nos. 30 and 31) : 



4thJiuie A = 21' 0'" 27^-0 E.G. 



= 20 27-2 



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

 longitude was had by a single series of altitudes at the artificial horizon 

 without roof (Obs. No. 61) : 



Nakitawa \ = 2'> 0™ 19^-6 E.G. 



,, = 30° 4' 54" „
