3o8 Voyage of the Novara. 



"II. That the direction of the true meridian line drawn 

 from this point to the nearest opposite shore of the South side 

 of the crater-basin was marked by an oblique (St. Andrew's) 

 cross. 



" III. That the tidal-gauge was situated on a rock near the 

 landing-place, and that the rise of the tide above the mean 

 level of the water (3 feet 5 inches), was marked on a slab of 

 rock smoothed for the purpose. 



" IV. Lastly. The magnetic observations were taken in a 

 hut erected for that express purpose on the little plateau behind 

 the settlers' huts, where at the same time various sorts of 

 useful trees were planted by the Expedition. 



" The names of the officers and naturalists who, under the 

 superintendence of the commander of the Imperial Expedition, 

 took part in the various scientific operations were : — for 

 Astronomy and Terrestrial Magnetism, Liuteenant Robert 

 Miillar ; Botany, Dr. Edward Schwarz and M. Jellinck ; 

 Geodesy and Meteorology, Lieutenant Eugen Kronowetter; 

 for the Trigonometrical Measurement of the Crater-basin, Lieu- 

 tenant Gustavus Battlogg; for Geology, Dr. Ferdinand 

 Hochstetter ; Ethnology and Physical Geography, Dr. Karl 



the Observator3\ Major Jacobs (whereas the nautical abnanack gave 5 h. 21 m. 

 3.77 sec.=80° 10' 0-|"). The longitude of St. Paul would be 5 h. 10 m. 5.2 s. East of 

 Greenwich (77"^ 31' 23" E.) The average of the two measurements gives as the 

 average 5 h. 10 m. 5*6 sec, or 77° 31' 20" E. to be assumed as the final longitude 

 of St. Paul, while the latitude was taken from the various means of tlie height of 

 the sun at the meridian on an average of days. An additional computation 

 in wliich allowances were made for the various corrections, gave, as tlie latitude, 

 38° 42' 47" S.
