being nearly evaporated, I diluted it with water, when all 
the seven new globules, as well as the two original ones, 
floated in the water, and appeared of precisely the same 
shape and white colour ; and three of the new globules were 
of the same size as the original ones, but the rest were smaller. 
When left on the glass to dry, the globules remained of the 
same shape and size as they were whilst floating in the 
serum. 
“ The above experiment I have repeated a great many times 
with human blood, as well as with sheeps' and calves’ blood, 
and the results have been always the same. When warm 
and fresh blood was used, the serum covering the surface 
of a 160,000 part of a square inch, produced from six to 
twelve globules, but when the serum was diluted with water, 
the number of globules produced was less, and they were 
smaller in size. 
“ On the 1 ith of August, 1817,1 poured half a pint of warm 
sheep’s blood into a glass vessel, and left it forty-eight hours 
at rest to coagulate : I then poured off’ the serum into another 
vessel, in which it remained at rest six hours ; with this se_ 
rum, a glass tube four inches long and three-eights in dia- 
meter inside was filled to overflowing, and closed with a 
good cork, and covered with a bladder. The serum was as 
clear as water; and although I examined it very attentively, I 
could not see more than fifteen or twenty globules in the 
whole extent of the tube. It was kept inverted in a glass 
of water. At the end of seven days, upon holding the tube 
between my fingers, which were tolerably warm, and examin- 
ing it with a double lens of considerable magnifying power, I
