the head of Ameba. But remembering the observations of 
Dr. J. Braxton Hicks on the occurrence of amceboid forms 
in certain undoubted vegetables, I was of course unprepared 
to assign them to a position in the chain of life without 
further study. To decide this question if possible, and 
ascertain the origin of these wandering masses of protoplasm, 
I watched them at intervals for the better part of two days, 
and I saw the following changes take place. From an 
almost hyaline condition the Ameba became gradually more 
and more granular, the granules increasing in dimensions until 
the individuals appeared to be packed almost full of dense 
oil globules. Then they came to a rest, or at least their 
hitherto lively movements were arrested, and presently near 
one end appeared evolved, so to speak, from the mass cilia 
one after the other until a crown of them was seen surround- 
ing what was plainly now,a defined locality. At the same 
time a change was going on all over the Ameba by reason 
of which at last from this simple mass of albuminoid 
material a true ciliated animalcule, belonging I believe, 
to either the genus Kolpoda or Paramecium, which resemble 
each other very much, was evolved. 
The question at once, then, presents itself, is not the 
amceba, in this case, the young sical condition of the ciliated 
animaleule? Such is my opinion. But we will require 
many more observations to decide whether, as Iam of opinion 
is the case, they all pass through this condition and also, 
at the same time to throw more light upon a field in 
which I have spent much time in observation, namely, the 
origin of these simple organisms like the Amebe. At 
some future time I may take the opportunity of detailing 
what I have seen in this direction. 
Dr. I. Wauz described a new method of Analyzing Titanif- 
erous Iron Ores, devised by himself. Under ordinary 
circumstances, and as described in the books, such ores, after 
pulverization are fused along with Acid Sulphate of Potassium 
in a Platinum crucible, and the Titanium Oxide thrown 
down from the solution of the mass in water by boiling. He
