mentioned tlien, and makes it more nearly similar to the others, 
in its tendency to bleed, for Dr. Miller told me, and here I use 
his own words as nearly as I can remember, “ the hemorrhage 
was very difficult to stop, so much so, indeed, that I began to 
feel uneasy, finding no blood vessels to tie.” As Dr. Miller said, 
“ I am not afraid when I can see blood vessels and apply a liga¬ 
ture, but there l wasP In the September number of the Review, 
I published a little note of the condition of the patient, and to¬
