1660, 1685), from the stomach of the common opossum, 

 Didelphis virginiana, from the Wistar Institute of Anatomy 

 and from the Zoological Gardens (P. Z. G. Lab., 324, 

 1166). 



54. Trwhuris trichiura, (Linn.), is recorded from the colon 

 of man (Path. Mus., 3; Path Hist., 148) in the records of the 

 two autopsies above referred to (50) under Uncinaria duo- 

 denalis. Ova of this worm have also been identified several 

 times in the stools of human beings (unrecorded). 



55. Trichuris suis, (Schrank) (Path. Mus., 16), from the 

 large intestine of the domestic hog, Sits scrofa, collected in 

 Iowa by Dr. J. J. Repp. 



56. Trichuris vulpis, (Frolich) (Path. Mus., 35), from the 

 large intestine of dog, Canis domesticus, in the laboratory. 



57. Trichuris ovis, (Abildgaard) (Path. Hist., 1901), from 

 the large intestine of an antelope, Antelope furcifer, in the 

 Zoological Gardens. 



58. Trichinella spiralis, (Owen) , has been met three times 

 (as the encysted larval worms) in human muscle, having 

 been once submitted (Path. Mus., 37) in a portion of the 

 pectoral muscles of a badly infested human cadaver in the 

 dissecting-room by Dr. J. K. Pollock, then a medical student 

 of this school; and twice having been found (Path. Hist., 189, 

 358) in the muscle of the diaphragm in autopsy material 

 from the Philadelphia Hospital. 



59. Filaria immitis, Leidy (Path. Mus., 6), from the right 

 heart and pulmonary artery of a dog used in experimentation 

 in the laboratory. 



60. Filaria equina, (Abildgaard) (Path. Mus., 19), from 

 the peritoneum of a horse, Equus caballus, collected in Iowa by 

 Dr. J. J. Repp. A second specimen was presented by Dr. 

 Repp, a single male example, which was taken from the 

 anterior chamber of the eye of a horse in Iowa (Path. 

 Mus., 7). The name Filaria oculi has been attached to 

 such examples; but the anatomy of the specimen leaves 

 no doubt in the writer's opinion that this is merely an 

 aberrant example of the species here named.
