(Plate 10. group I.) and of others at the most active period of inflamma- 

 tion (group II.). These have all been most carefully drawn under the 

 camera, each fibre and line being actually copied as they appeared in situ 

 in the field of view of the microscope, some processes and other bodies 

 being omitted for the sake of clearness, and the peripheral members 

 of the group sometimes brought nearer to the centre to save space. 

 Numerous other preparations were made at all stages of inflamma- 

 tion, commencing with five hours, when little or no change was ob- 

 servable, up to five and seven days, when, in the case of inflammation 

 induced by nitrate of silver, the effects had passed off, leaving no 

 recognizable traces. 



EXPLANATION OF PLATE 10. 



Group I. 



Corpuscles of the Normal Cornea. 



Fig. 1. Two corpuscles, isolated, of a vacuolated appearance ; nucleus indistinct, pro- 

 cesses much anastomosing. 

 Fig. 2. Two similar corpuscles. 



Fig. 3. A single corpuscle, showing reduplication of nucleus and nucleolus, and what 



might be taken for segmentation of its substance. 

 Fig. 4. Two typical normal forms. 



Fig. 5. A single corpuscle, with very large and strongly defined nucleus. 



Group II. 



Corpuscles'of a Cornea 48 hours after commencement of inflammation by application 



of Nitrate of Silver. 



Fig. 6. A group of fixed corpuscles (c) and wander cells (w). The latter are seen to be 

 of diversified form and in an active state of cell-division. The appearances 

 which the fixed corpuscles present are all paralleled in the figures of normal 

 preparations, and, notwithstanding the activity of the inflammation, as evi- 

 denced by the state of the wander cells, there is no appearance of pro- 

 Hferation nor of any thing abnormal in these. 



Fig, 7. A corpuscle with conspicuous nucleus and two wander cells (tv) clinging to its 

 processes. 



Fig. 8. Two corpuscles, the one vacuolated and with nucleus distinct, the other 

 similar to fig. 3, group I.
