C' ON THE PRESENCE OF TRICHINAE IN ADIPOSE TISSUE. 
By M. Chatin. 
All authors represent trichinae as peculiar to muscular tissue, 
and are agreed in affirming its absence in adipose tissue, which 
should therefore possess an absolute immunity. 
From the researches of the author, however, we are led to 
the conclusion that the presence of trichinae in adipose tissue 
cannot hereafter be denied. The fact is interesting in the point 
of view of the natural history of the helminth, and perhaps 
also in respect to the prophylaxy of trichinosis. “ It is necesary, 
however,” says the author, “ to observe the condition which 
characterizes most of the worms found in fat, to wit: that they 
are almost always free, or scarcely attached to the surrounding 
elements ; one might consider them then as nematods which have 
not yet reached their normal station, if the presence of encysted 
trichinae did not demonstrate the possibility of these parasites to 
accomplish, in that medium, the stage period of their existence. 
I even believe that the study of encysted trichinae in fatty sub¬ 
stance will contribute to elucidate the mode of the constitution 
of the cyst, a question upon which at the present time, helminthol¬ 
ogists do not agree.” 
Such are the results given by observation ; in respect to ex¬ 
perimental facts, I limit myself to saying that animals in whose 
alimentation I had introduced these fats have not yet presented 
any morbid phenomena, while subjects of the same species, nour¬ 
ished with the muscular structure of the same parts, have pre¬ 
sented the characteristic symptoms of intestinal trichinosis, which 
has already killed four of them. It seems then that the no vi¬ 
cious action of tricliinosed lards is quite feeble ; but several facts 
throwing on this a certain doubt, it is indispensable to continue 
our researches and experiments. 
At any rate, the presence of trichinae in adipose tissue, 
especially of the encysted variety, demands a careful and final 
solution of the question of their possible presence in suspected 
meats, and the precautions properly following .—Gazette Medi
