INFESTING THE MUSCLES OF THE HUMAN BODY. 319 
habitat in the interior of living animal bodies. Referring it, however, provisionally, to 
the class Entozoa of Rudolphi, in which it would indicate a new order, its generic cha- 
racter may be thus given: 
Genus TrIcHINA. 
Animal pellucidum, filiforme, teres, posticé attenuatum : os lineare ; anus nullus ; tubus 
intestinalis genitaliaque inconspicui. (In vesicd externd, cellulosd, elasticd, ple- 
rumque solitarium.) 
TRICHINA SPIRALIS. 
Trich. minutissima, spiraliter raro flecuosé incurva; capite obtuso; collo nullo; cauda 
attenuatd obtusd. (Vesicd externa ellipticd, extremitatibus plerumque attenuatis elon- 
gatis.) 
Hab. in Hominis musculis (preter involuntarios) per totum corpus diffusa, cre- 
berrima. 
With respect to the case in which this singular parasite has been met with, Dr. Rou- 
pell, Physician to St. Bartholomew’s Hospital, has obligingly forwarded to me the fol- 
lowing notes. 
“Paolo Bianchi, an Italian, by trade a barometer-maker, about 50 years of age, of a 
sallow complexion, with black hair and eyes, was admitted under my care on the 4th of 
December, 1834. When admitted he was much emaciated and weak, his countenance was 
haggard, and his look depressed. His legs were cedematous ; his urine contained albu- 
men, was sweet, and when evaporated yielded a residue like treacle: he had pain in the 
back. His appetite was deranged, and his liver was felt beyond its natural limits. He 
had cough, but without urgent distress or hurry in the breathing or expectoration ; on 
auscultation pectriloquy was detected in the upper part of the lungs: his bowels were 
relaxed. The general treatment was to give him strength by tonic and sedative medi- 
cines, with a nutritious but not stimulating diet, and leeches were applied to the loins : 
for a time he appeared to gain ground, the cedema disappeared, and he gained some 
strength, being able to get out of bed and dress himself. But his appetite rather sud- 
denly failed him ; his diarrhoea increased ; his abdomen became tense and painful ; his 
stools passed unconsciously and contained blood ; and having received extreme unction 
from his priest, he died on the 29th of January, 1835, in a state of extreme debility and 
emaciation. There had not been observed any eruption on the skin, or any greater loss 
of muscular power than related to the debility caused by the disease of which he died. 
‘‘ He was examined thirty-six hours after death. Tuberculous cavities were found in 
the upper lobes of the lungs on both sides, and specks of tubercles in both. The kid- 
neys presented in a marked degree the change described by Dr. Bright. The liver was
