smaller ones the capsule is much less distinct. 

 (2) Groups of bodies like those represented in fig. 4, 

 PI. I. Some of these are capsulated, but in others 

 there is no distinct boundary between them and the 

 surrounding liver tissue. (3) Other bodies similar to 

 the larger ones shown in fig. 4, PI. I, each enclosed 

 in a A^ery distinct capsule, with an outer investment of 

 fibrous tissue. Between all these foreign bodies is the 

 hepatic tissue, perfectly normal and well preserved in 

 spite of the formalin fixation. 



The infection of the ovaries is relatively slight. In 

 these organs the germinal epithelium is thrown into 

 deep longitudinal folds projecting into the cavity of the 

 organ. The epithelium itself is very thin and the ova 

 are on its internal surface — within the folds. Among 

 the ova, sometimes apparently attached to the epithelium, 

 but in other cases lying quite loosely, are foreign bodies 

 essentially similar to that shown in fig. 1, PI. I. 

 They are, however, few in number, but still abundant 

 enough to show up clearly when the organ was examined 

 by means of a hand-lens. 



Fig. 1, PI. I, represents a part of a section of 

 the renal organ. For the most part the foreign bodies in 

 this organ are of the type figured here. A fairly thick 

 fibrous capsule surrounds a mass of tissue containing 

 very numerous small nuclei. In the centre of this there 

 is usually a thick, densely staining, structureless capsule, 

 which is sometimes crumpled or collapsed, and usually 

 empty. Sometimes, however, this capsule contains a round 

 body like those shown in fig. 4. As a rule the nuclei 

 are imbedded in a granular mass of no very definite 

 structure, but sometimes they appear to be the nuclei of 

 small cells lying fairly distinctly from each other. In 

 most cases the intrusive bodies in the renal organ consist
