INJECTION OF PUTRID MATTER INTO THE VEINS. 523 
of whey-like fluid within the thorax. Pleurae reddened, and 
patched with adhesions on the right side to the pericardium. 
Heart extremely soft; its texture broken down easily. Lungs 
hepatized in one part; in others, presenting tuberculous masses 
of pultaceous matter. Bronchial membrane uniformly red. 
These are the appearances, but little varied, which such cases 
ordinarily present; only that, in this instance, they were compli¬ 
cated with a local affection of the respiratory organs, a paiticula- 
rity which may sometimes supervene, as Messieurs Dupuy and 
Trousseau have before observed in their interesting Memon on 
the same subject. 
From this one experiment, followed up by several others which 
were instituted for the sake of ascertaining the most salutary mode 
of treatment in such and similar cases, M. Hamont observes, that 
the influence of putrid matters thrown into the veins has been 
manifested by all organs; but that the lungs , the heart , and some¬ 
times the large vessels , are those which have manifested these 
effects the most. The digestive tube has, in the greater numbei 
of instances, merely exhibited its villosities blackened , its glands 
tumefied; but rarely evident traces of phlegmasia. This disco¬ 
loration of the villi is well worthy the attention of pathologists. 
It is only seen in typhoid and putrid affections; also, we have 
observed it numerous times this last year in horses who have died 
of the fatal epizootic which raged in the environs of Paris. 
The peculiar condition of the blood, most commonly that of 
liquidity ; the flaccidity of the general muscular tissue, the bloody 
eff usions ( petechiw ) in different parts of the body, are all alteia- 
tions met with in animals who die of carbunculous or other typhoid 
affections; a resemblance we ought not to feel surprised at, when 
we know that the causes assigned by authors for typhus are, 
generally, stagnant water , bad f orage , and insalubrious localities , 
—in which air, charged with deleterious emanations, enters the 
blood through the medium of respiration (as M. Miguel has told 
us), changing the nature of that fluid, and reaching through its 
medium to the brain, the heart, &c. producing therein more or 
less mischief. 
Whatever may be the mode of action of these agents, our ex¬ 
periments on their treatment go to show, that purgatives adminis¬ 
tered early constantly aggravate the malady, and seem to accele¬ 
rate death. On the other hand, general bloodletting, at this 
time, has furnished us with quite the contrary results. 
If we consult authors on the treatment of typhus in quadru¬ 
peds, we find that Vicq-d’Azir has had reason to praise general 
bloodletting; though he judiciously observes, that if not had 
recourse to early, it will do harm. Brugnone, in a carbunculous
