"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, Lieutenant Robert Müllar; Botany, Dr. Edward Schwarz and M. Jellinck; Geodesy and Meteorology, Lieutenant Eugen Kronowetter; for the Trigonometrical Measurement of the Crater-basin, Lieutenant Gustavus Battlogg; for Geology, Dr. Ferdinand Hochstetter; Ethnology and Physical Geography, Dr. Karl Scherzer; Zoology, G. Frauenfeld and J. Zelebor; Draughtsman and Artist, Joseph Sellemy."

PLATE V.—TRACK FROM ST. PAUL TO POINT DE GALLE. (CEYLON).
[Larger.]

Towards 5 p. m. the last boat came off with the measuring and levelling instruments, and various articles of baggage.[68] The embarkation was finally completed. Half-an-hour later the Novara weighed anchor, and we steered, favoured with most splendid weather and full of pleasing anticipations, for the adjacent island of New Amsterdam. Not without sundry twitches of sadness did we remark the sharp crater of St. Paul gradually fade away like a vision in the gloom of approaching night; and many undying memories must attach to our residence on that lonely, world-forsaken island.

[68] Remembering how many bottles and glass tubes were shattered, we have not thought it beyond our province to recommend future scientific travellers to bring with them a good supply of duplicates of all instruments liable to breakage, as it is very difficult to get such insignificant articles replaced out of Europe, and we frequently found on this occasion the want of some such little instrument interposed an obstacle to the further usefulness of the instruments.

And now, at the moment of our departure from the island, be it permitted us to cast a retrospective glance at the various results obtained by the Expedition of the Novara during her stay at St. Paul.
