^n Anatomical Description of IVorms,* found in the Kidneys of IVolves. By 

 Mr. James Theodoras Klein, Secretary of the City of Dantzic, F. R.S.

These worms were sent to Mr. Klein from Sewaldia, in Eastern Prussia. 



Fig. I, pi. 10, represents a female worm found in the kidney of a she 

 wolf. 



Fig. 2, the kidney of a wolf, resembling a bag, on account of the almost 

 entire consumption of its parenchyma. It contained 8 worms ; some of a 

 yellowish, others of a blood colour; 2 of which were females, and 6 males. 



The females were more than twice longer and thicker than the males. They 

 were furnished with three very visible holes; the first of which performed the 

 function of the mouth; the second of the anus; the third of the vulva. This 

 last hole is seen under the belly, about 1^ inch from the mouth; as at abc 

 in fig. 3. 



The membranous skin was marked with annular fibres, and 7 or 8 chestnut- 

 coloured lines, as at d, running the whole length of the worm. The skin 

 being cut, a limpid humour issued forth, and then appeared the transversal 

 fibres interlaid on every side with the viscera, and are all round about inserted 

 into the skin in the interstices of the vesicles, and at the same time the 

 viscera appeared, which the sole parts destined for nutrition and generation 

 seem to make up. 



The alimentary passage is composed of two canals, one of which bb, fig. 4, 

 begins at the mouth, and is about 2 inches long, smooth, fleshy, whitish, and 

 endowed with thick coats, serves for receiving the nourishment. As this duct 

 proceeds with equal thickness, it is once reflected and retorted before it enters 

 the other, cccd, which is of a dark brown colour, much broader and tenderer 

 than the first, flatted, membranous, covered with very fine coats, wrinkled like 

 a swathing cloth, then runs into transversal and winding sinews, and extends 

 in a straight line to the anus. The inner coat of this canal seemed somewhat 

 rough, and as it were strewed with dust. The contained liquor was perfectly 

 fluid, and of a faint sooty colour. 



Near the anus was fixed to the skin, the end of a whitish tender vessel, 

 which thence proceeded straight to the beginning of the alimentary canal, 

 where reflecting towards its origin, and again resuming its first way, after being 



• These worms appear to belong to the Liniiaean genus ascaris.
