PERFORATION OF THE BLADDER.

must confess, we have not succeeded in discovering any that 
bring conviction to our mind, that, in what we understand by 
“the circulation of the blood,” there is actually a gaseous as well 
as a liquid current . That arterial blood, suddenly arrested in its 
course, may, and does, even from the moment of its arrest, 
commence and continue to evolve air, with which we know it to 
be charged, is, we think, demonstrated by Mr. Turner’s ingenious 
experiments; the evolved gas, or air, being, at the time the 
blood was in actual circulation, in chemical combination with it — 
not, as we apprehend Mr. Turner’s meaning to be, mechanically 
commingled with it. Will the same gaseous evolution result from 
the imprisonment by the machine of venous blood? We feel 
anxious for an account of his “ venous experiments ; ” the one 
inserted in the present Register, being, by Mr. Turner himself, 
considered unsatisfactory, from the circumstance of the clasping 
machine requiring, on account of the tardiness of the current of 
the blood in the veins, “ considerable modification.” In the mean 
time, for his bold enterprises in the cause of medical science, and 
for his frank and faithful account of them, in a pamphlet that will 
be read with equal interest by surgeons and by veterinary 
surgeons, he deserves the acknowledgments of us all. Trodden 
as the path has been, and distinguished as the footsteps are trace- 
able thereon, we think, with Mr. Turner, that the “ whole truth” 
has not yet been elicited ; and farther, that, from the novelty 
of his experiments, our author is in a fair way of telling a little 
“ more truth.” 
PERFORATION OF THE BLADDER BY AN OSSEOUS 
TUMOUR OF THE SYMPHYSIS PUBIS. 
By M. Gasp ard Barthelemy. 
The case which I am about to state has never, so far as I 
know, been recorded in the history of human or veterinary pa- 
thology. Although the organic lesion which is here described 
is incurable, and, perhaps, can scarcely be recognised during the 
life of the animal, the case is a very curious and interesting one 
in an historical point of view. 
A bay Hanoverian horse, of good constitution, and seven years 
old, three years of which time had been passed in the gendarme- 
rie, and that had on no occasion exhibited the least symptom of ill- 
ness, was, on the 25th of J uly, 1835, seized with violent colic. The 
veterinary surgeon was summoned, and, on my arrival at the 
stables, I found the horse in a state of much suffering, pawing 
with his feet, and lying down and getting up again without
