ANTAKCTIC INFUSORIA 59 
On the second voyage, the Journal records, December 21, 
1841 : 'Much of this ice is discoloured, as was the case last 
year and from the same cause. When melted it gives out a 
strong animal smell.' And again, off Louis Phihppe Land, 
December 28, 1842 — a point repeated in the letter to his 
father of March 7, 1843, describing the voyage : 
All day the washed pieces of pack ice have been stained 
with yellow, caused doubtless by the infusoriae in the 
stomachs of the Salpae, which are washed up against the 
ice and leave this stain (the same as last year). When the 
wind was Hght and the fog thick in the morning, I recognised 
the animal smell very strong from the pack, precisely similar 
to that of brash ice, with the Salpoid remains, omitted last 
year by me, in the cabin. 
Letters to Ross after their return (September 1 and 4, 
1844) speak of two pamphlets on Antarctic Infusoria received 
from Ehrenberg — ' in hard German,' one containing descrip- 
tions, the other ' drawings of Aster om'phalos Humholdtii, 
Cuvierii, Rossii, Darwinii, and Hooherii. 1 think, Sir, that 
we are in good com^pany, though I can give you no more idea 
of what the species are like further than that the magnified 
figures resemble the objects at the far end of a kaleidoscope.' 
Before this was sent on to Ross, Hooker * commenced trying, 
with the German dictionary, to spell out [the] descriptions of 
our Infusoria.' 
I find Ehrenberg has described 70 new species from the 
contents of two pill-boxes and three small bottles, and has 
not yet examined the whole of what I had. As far as I can 
make out they seem to throw extraordinary light on the 
subject, and to have been the most important collections 
ever brought to this country. The amount of species in 
what you have must be enormous, as my specimens were 
mere scraps in pill-boxes from the dredge, and a portion of 
a large bottle you have of condensed brown Ice. 
Tlie other packets I sent were of dirt from the roots 
of Cockburn and other Island mosses, which also seem to 
contain animals. . . . Ehrenberg finds animalculae in all 
soundings, and I feel quite convinced that those you have
