Desiring last year to make, in a granulated form, an alloy 
consisting of # nickel, 4 copper, I caused a mixture of the 
oxyds of those metals in the due proportions to be heated in 
closed crucibles with charcoal in a blast furnace; by this means 
reduction and fusion resulted, and the fused alloy was poured 
into water at a high white heat. 
Among the granulated metal were found large numbers of 
hollow spheroids varying in size from peas to large chestnuts, 
many of them imperfect and torn, but many of them tolerably 
regular in shape, one side being usually bright and smooth, 
while the other was rough and pimpled. 
As, upon crushing these with a hammer, the anvil was moist- 
ened, I examined a considerable number of them and found 
that they were nearly full of water, so that the water distinctly 
rattled within them when shaken, and showed itself in quanti 
when the larger spheroids were carefully broken. Fluid metal, 
poured white hot into water, had formed metallic bulbs filled 
with water.
