4. 1 hat the dust did not necessarily and evidently come from 
Africa, as being the nearest land, although the wind blew from 
thence when the dust fell; for this reason, that no exclusively 
African forms are among it. 
5. That as Himanlidium Papilio, a very marked form, has 
hitherto occurred only in Cayenne (see the Mikroskopische 
Leben in Slid- und Nord-Amerika, plate 2, fig. 2), and as the 
Surirella is also probably an American form, only two conclu¬ 
sions present themselves ; either that the dust was raised in South 
America into the upper strata of air, and brought by a change of 
the current in another direction, or Himanlidium Papilio, together 
with Surirella, likewise occur elsewhere, namely, in Africa. 
Review of the Results of these Investigations. 
1. Not only is there, as resulted from the former observations 
of the author (vide d. Mikroskopische Leben in Amerika, Spitz- 
bergen, &c.), an invisible minute creation in the neighbourhood 
of the Pole, where the larger animals can no longer subsist, but 
a similar creation is highly developed at the South Pole. 
2. Even the ice and snow of the South Polar Sea is rich in 
living organisms, contending successfully with the extremity of 
cold. 
3. The microscopic living forms of the South Polar Sea contain 
great riches hitherto wholly unknown, frequently of very elegant 
shape, since no less than seven peculiar genera have been disco¬ 
vered, of which some contain several, one as many as seven species. 
4. The forms collected in the year 1842, near Victoria Land, 
were capable of being examined in an almost fresh state in Berlin, 
in May, 1844, which shows how long preservation is possible. 
5. The ocean is not only populated at certain localities, and in 
inland seas or on the coasts, with invisible living atoms, but is pro¬ 
portionately thickly crowded with life everywhere in the clearest 
state of the sea-water and far from the coasts. 
6. Hitherto but one perfectly microscopic form from the high 
sea was known, and even that from the neighbourhood of the
