Descriptions of Plates.^ 

 Plate I. ■ 



Intertracheal tumom- of a calf, as a sequel of drenching. (Natural size.) 



Plate II. 



The incrustations of iibrine and leucocytes specific for pleuro-pneunionia. 



Kockel's fibrine stain, bordeaux red (1 ; 62). 



Plate in. 



Fig. 1. — Interstitium of the lungs ; lymph spaces with incrustations of leucocytes- 

 Parenchym in different stages of croupous pneumonia (1 : 10). 



Fig. 2 (Case 1). — Subcutaneous tissue with typical lymphangitis and periarteritis. 



Fibrine stain (1 10). 



Fig. 3 (Case 4). — Progressive stage of lymphangitis and periarteritis, incipient 

 cicatrisation. Van Gieson's stain (1 ; 70). 



Plate IV. 



Fig. 4 (Case 7). — Traverse section through'a piece of the tail. Wide lymph 

 spaces, dissociation of muscle fasicles, and in places changes in the blood vessels. 

 Haemalum and eosine (1 : 4). 



Fig. (Case 7). — Portion of same section enlarged,- show^ tangles of capillaries 

 and incrustation of leucocytes (1 : 80). 



Fig. 6 (Case 1).^ — Transverse section through a muscle. Shows incrustation of 

 leucocytes in the perimysium internum and around the blood vessels. Van Gieson 



(1 60). 



Fig. 7 (Case 1). — Portion of same section with muscle fibres enlarged (1 : 10). 



Fig. 8 (Case 6). — Changes of the tissue around necrotic muscles. The incrusta- 

 tion of leucocytes around blood vessels is in concentric rings. May-Gruenwald-Fisoher 

 (1 4). 



Plate V. 



Fig. U (Case 6). — External lesions of articulations. The large swelling on the 

 right fetlock joint is due to pleuro-pneumonia. 



Fig. 10 (Case 1). — Lymphatic glands, shows thickening of capsule, thrombosis 

 of blood vessels of hylus, and serose infiltration of cortex sinus. Van Gieson (i . lO). 



Plate VI. 



Fig. 11 (Case 10). — Traverse section of rectum. (Reduced to 0*6 natural size.) 

 Fig. 12 (Case 10). — Rectum laid open longitudinally. (Reduced to • 6 natural size.) 



Plate VII. 



Fig. 13 (Case 10). — Lesions in the rectum, mucosa, niuscularis mucosae, sub- 

 mucosa and the beginning of the intermuscular plexus. Van Gieson (1 4). 



Fig. 14 (Case 10). — Lesions in rectum (same section as Fig. 13). Intermuscular 

 plexus, longitudinal muscles and serosa. Van Gieson (1 : 4). 



Fig. 15 (same case as Plate I). — Pleuro-pneumonia tum.our in section of trachea. 



Haemalum-eosiue (1 ; 4).
