GLANDERS. 



EXPLANATION OF ILLUSTRATIONS. 



[These illustratious arc xiliotographic copies of the plates accompanying Professor 

 Gerlacli's treatise on glanders, publisliecl in the Jahresherichi dei' Koeniglichen Thier- 

 arzneisclmle zu Hannover, 1868. The same illustrate the morbid anatomy of glanders.] 



Plate I. — Fig. I. Development of glanders-cells of connective-tissue corpuscles in 

 the mncous membrane of the septum. Enlargement 300. 



1. Spindle-shaped cells, with a large oval nucleus. 



2. The same, move swelled ; nucleus larger ; a second nucleus developing. 



3. Cells like No. 2, but with ends blunted ; more granulated and approaching decay. 



4. Eonnd cells of different size, with a large nucleus ; the largest ones have a dark, 

 granulated nucleus; beneath free nuclei and granulated detritus. 



Fig. II. Microscopic cut from gray-yellowish glanders ; nodules of the mucous mem- 

 brane of the sejitum, in which (cut) can be seen spindle-shapetl cells in different 

 stages of development to round cells with a fibrous intercellular substance. Enlarge- 

 ment 300. At a the spindle-shaped cells and at 6 the round cells prevailing. 



Fig. III. Development of glanders-cells of epithelium elements in the pulmonal 

 nodules. Enlargement 300. 



1. Normal cylinder-cell with a nucleus. 



2. Cylinder-cell with a second nucleus developing. 



3. Cylinder-cell with two and three developed nuclei. 



4. Bag-shaped rudiments of cylinder-cells filled ■with young round cells. 



5. Giant-cells with young round cells. 



6. Small and large round cells with a large, dark, and granulated nucleus. 



Plate II. — Fig. IV. Lower end of the septum with glanders-nodules and ulcers. 

 (Natm-al size.) 



1. Various gray glanders-nodules. 



2. A group of glandcrs-nodnles with a round hole in the middle. (Incipient 

 glanders-ulcers. ) 



3. A solitary glanders-ulcer. 



4. Confluent glanders-ulcers with elevated borders and dirty bottom. 



Fig. V. Transversal cuts through the gray nodules in the mucous membrane of the 

 septum. (Natural size. ) 



a. Gray nodule in the midst of the tissue of the mucous membrane; the upper layer 

 of the mucous membrane raised. 



b. Gray nodule in the upper layer of the mucous membrane, visible on the surface. 

 Fig. VI. A piece of the lower border of a lung, cut surface. (Natural size.) 



1. Miliary tubercles. 



2. Tubercle of the size of a pea. 



3. A large glanders-nodule developing. 



Fig. VII. Also a piece of the lower border of a lung, cut surface. (Natural size.) 



1. Miliary nodules suiTOunded by a red crust. 



2. Large gray glanders-nodule (glanders excrescence) growing yet in one direction.
