I.—Astronomic Observations. 
Kaibo .—Latitude determined by a circummeridian 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) :

Duwona .—With the approximate value X = 2 1 ' l m 17 s East Greenwich, the 
latitude is calculated by a meridian altitude observed on going (Obs. No. 24) :

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