CAVITY OF THE THORAX IN THE HORSE. 679 
been operated on by M. Willems : a result he desired to have 
concealed, under the pretext that it was not expedient to 
exhibit facts of this description to strangers, lest such (facts) 
might alarm them about the consequences of such operations.

but become pneumonic, had been made in presence of the 
governors of the province. 
5thly. Because, in my letter of the 2d August, 1852, 
I had communicated to the Central Commission the indelicate 
result of the experiments made at Meuling 5 s house at Hulst. 
6thly. Because I had furnished the Central Committee with 
proof that the heifer from the stables of M. Fabrez, and 
slaughtered on account of pleuro-pneumonia, had been in- 
oculated.” 
We cannot find room for more of M. Maris 5 brochure 
of replication. We have said enough, we conceive, to give 
our readers an inkling, that Professor Simonds drew from 
his fair and judicious experiments, a pretty correct deduction, 
when he said, “ that the severity of pleuro-pneumonia is in 
no ways mitigated by previous inoculation, the disease 
proving equally rapid in its progress and fatal in its conse- 
quences in an inoculated as in an «minoculated animal.” 
And now, it must be patent to everybody what M. Maris 5 
opinions are of Dr. Willems 5 (e systeme 55 of inoculation as a 
prophylactic against pleuro-pneumonia.

CONSTRUCTION OF THE CAVITY OF THE THORAX IN THE 
HORSE, CONSIDERED WITH RELATION TO DIAGNOSIS 
BETWEEN DISEASES OF THE CHEST. 
By Dr. Muller, of the Veterinary Institute of Vienna. 
(Translated and Analysed from the Magazin fiir del Gesammte 
Thierheilkunde .) 
Great pains have been taken of late to arrive at a knowledge 
of the symptoms proper to make the requisite distinction 
between the different diseases of the chest during the life of 
the animal. By analogy with what is done in man, essays of 
auscultation and percussion have been made in the horse ; 
the matter, however, has shown that, from the construction 
of the thoracic cavity, as well as from his own observations,
