NATURE NOTES. dip 
fortunes of one of the new sun-animalcules, and saw that its 
share of the original band (the two narrow strips before 
mentioned) resembled two pseudopods somewhat longer and 
thicker than their fellows. In one of them I noticed a 
couple of granules such as are usually found only in the 
body of the animalcule; the pseudopod was distended round 
them, and they were clearly out of place (see fig. 4). Ina 
short time, however, they slowly moved down the pseudo- 
pod, and were absorbed into the main body. 
Fig. 1 was drawn from a specimen which was changing 
its shape very slowly, and the drawing may therefore be 
considered as fairly accurate. The other figures were drawn 
from a creature that was changing very rapidly, and were 
made from memory after the process was complete. They 
may therefore perhaps not be quite accurate, and are at all 
events to be considered as to a certain extent diagrammatic. 
I believe, however, that the curvature of the pseudopods, 
which is one of the most noticeable features in the drawings, 
is correctly represented. BEATRICE SPRAGUE. 
LIVINGSTONE’S TREE. 
I sHOULD like to make a few remarks on what was perhaps 
the most interesting tree in the whole continent of Africa. 
Both black men and white regard this tree with venera- 
tion, since under its branches Livingstone’s heart lay buried. 
About a year ago this tree began to show signs of decay, 
and in order to preserve the inscription it has been recently 
cut down. The inscription contained these simple and im- 
pressive words— 
“Dr LivinestonE Diep on May 4ru, 1873.” 
From the branches of this tree a number of slices were cut, 
stamped with the Government seal, and given to those who 
were considered likely to prize them. 
One of these I saw, and the paler central portion is in 
the form of a heart, a coincidence certainly, but a curious
