always pursued with an earnestness and persistency that followed 
him in his career as a practitioner, and which were making for him 
a large practice and much credit for his ability in the field of his 
labors. Of the others personally I can say but little, save that 
they all were in the enjoyment of good practices and daily in¬ 
creasing their sphere of usefulness, when that awful and final sum¬ 
mons called them from this world, and left to us the sad duty of 
recording an unfinished page in our history, and but a partially 
completed professional career. 
INOCULATION OF BACILLAR PHTHISIS. 
(Extracts from Mr. G. See on Phthisis Pulmonalis.) 
The true, direct, efficacious cause of the tuberculous process is 
resumed, in a single word only : the bacillus. 
Histology gave no answer to the question of the nature of 
tubercle, and could neither establish the precise characters of the 
perituberculous inflammatory nature, nor distinguish the true tu¬ 
bercle from those common inflammatory products known to-day 
as pseudo-nodules. The powerful intervention of experimental 
pathology was necessary to terminate these byzantinal discussions 
upon the connections of the tubercles with the phlegmasia. It 
will demonstrate conclusively that phlegmasias, so called, peri¬ 
tuberculous, are entirely of the domain and even of the nature of 
phthisis ; it will prove, besides, that the tuberculous nodule, not¬ 
withstanding its close resemblance to the false tubercle, presents 
an unalterable, though at the same time characteristic, property. 
This is the transmissibility ; it is the inoculability, after two or 
three generations, by successive cultures. How has experimental 
pathology proceeded to reach these positive results ? It has 
simply to reproduce the disease, entirely, and under all its forms. 
To reach this it has introduced into the organism of the superior 
animals, through their various roads of absorption, tuberculous 
matter, or rather the parasite which produces its viruiency. 
The processes of experimentation consist precisely in intro¬ 
ducing the tuberculous substance; 1st, by an insertion of
