CHAP. I.] THE EQUIPMENT OF THE SHIP. ot 
bon, Socotra, St. Paul’s, and Amsterdam Islands, Prince Hdward’s, the 
Crozets, and Marion groups. Of the E. African coast to the north of 
Natal no part is well explored, and the greater part is utterly unknown 
botanically. 
4, Paciric Ocran.—1. N. Temperate.—Collections are wanted from 
N. Japan and the Kuriles and Aleutian Islands. 2. Troprcat.—Consid- 
erable collections have been made only in the Sandwich Islands, Fiji 
Islands, Tahiti, and New Caledonia; from all of which more are much 
wanted. The Marquesas, New Hebrides, Marshall's, Solomon’s, and 
Caroline’s, together with all the smaller groups, are still less known. Of 
the American continent, the Californian Peninsula, Mexico, and the 
whole coast from Lima to Valparaiso, are but imperfectly known. Of 
the small islands off the coast, Juan Fernandez and the Galapagos alone 
have been partially botanized. 3. S. Temprrate.—Juan Fernandez, 
Masafuera, St. Felix, and Ambroise, Pitcairn, Bounty, Antipodes, E’me- 
rald, Macquarie Islands. 
5. Inpran ArcurpELAGo.—Java alone is explored, and the Philippines 
very partially ; collections are especially wanted from all the islands east 
of Java to the Louisiade and Solomon Archipelagos, especially Lombok 
and New Guinea. Siam, Cochin China, and the whole Chinese sea-board 
want exploration. 
6. Austratra.—All the tropical coasts are very partially explored. 
Photographs or careful drawings of tropical vegetation often convey 
interesting information, and should contain some reference to a scale of 
dimensions. 
An inquiry of much importance, for which the present expedition af- 
fords a favorable opportunity, is that into the vitality of seeds exposed 
to the action of sea-water. 
Observations should especially be made on the fruits and seeds of 
those plants which have become widely distributed throughout the trop- 
ical regions of the world, apparently without the intervention of man ; 
but further observations on other plants of different natural orders may 
be of great value with reference to questions of geographical distribution. 
The following instructions have been drawn up for the botanical col- 
lectors as to objects of special attention at particular places: 
Porto Rico.—In collecting, distinguish the plants of the savannas 
from those of the mountains, which, if possible, should be ascended. 
The palms and tree-ferns are quite unknown; marine alge also are 
wanted.
