EXPLANATION OF THE PLATES. 



PLATE XII. 



MUCUS. 



Fig. 1. Represents an example of vaginal mucus obtained 

 during parturition, and containing blood corpuscles. 



Fig. 2. Is a representation of cesophageal mucus. 



Fig. 3. Exhibits the mucous corpuscles contained in some 

 bronchitic mucus, and obtained from a patient labour- 

 ing under chronic bronchitis. The mucus was ropy 

 and tenacious, and many of the corpuscles were 

 rendered of an oval form by the pressure exerted 

 upon them by the filaments, of which the fluid por- 

 tion of true mucus is constituted. 



Fig. 4. Vegetation contained in the same mucus as that from 

 which the previous figure was made. 



Fig. 5. Mucus from the stomach. 



Fig. 6. Is a representation of the vaginal tricho-monas of 

 Donne, copied from the atlas appended to the 

 " Cours de Microscopic." 



It may here be observed that the above is the 



only instance of a copied figure being introduced 



into this work, and that in no case where it is pos- 



- .sible to procure subjects for original drawings will 



copied ones be admitted.
