DESCRIPTION OF PLATE XXIII, 



Illustrating Prof. Boettclier's Paper on the Structure of 

 Red Blood-corpuscles. 



Figs. 1—6. — Red blood -corpuscles of man after treatment with a concen- 

 trated alcoholic solution of corrosive sublimate and staining 

 with carmine. 

 The colouring of the drawings has been omitted. 



Fig. 7. — Human blood-corpuscles from the body of a person wlio died from 

 poisoning by corrosive sublimate. 



Fig. 8. — Red blood-corpuscles of the camel, treated in the same manner as 

 those in Figs. 1 — 6. 



Figs. 9 and 10. — Red blood-corpuscles of the frog after treatment with a 

 concentrated alcoholic solution of corrosive sublimate. Ex- 

 amined in water. 



Fig. 11. — Frog's blood-corpuscles treated in a similar manner, after stain- 

 ing with carmine. 

 A more exact explanation of the figures is given in the text. 



EXPLANATION OF PLATE XXIV, 



Illustrating Dr. E. Klein's Memoir on Epidermis of 

 Sheep-pox. 



Fig. 1. — From a vertical section through the rete Malpighii of pustule of 

 sheep-pock. 

 V. Vesicles in the epidermis, containing a small amount of fibrinous 



material. 

 t. Intercellular paths distended ; in it can be seen the " spikes" of 



the " ridge-and-furrow cells." 

 e. Epithelium cells of rete Malp. (Hart. Ill, 7). 

 Fig. 2. — Vertical section through the epidermis of sheep-pock. 



a. Deep layers of cells of rete Malpighii. 



b. Middle layers of rete Malpighii. 



c. Layers of " granular cells." 



d. Superficial layers of rete Malj)ighii. 



e. Stratum lucidum. 



/. Stratum corneum (Hart. Ill, 7). 

 Fig. 3. — From a transverse section through the central part of a (primary) 

 pock, stained with carmine and haematoxylin. 



a. Deep layer of rete Malpighii. 



b. "Granular layer" of rete Malpighii. 



c. Median horny streak or median stratum lucidum. 



d. Superficial portion of rete Malpighii. 



e. True stratum lucidum. 



/. Stratum corneum (111, 5). 

 Fig. 4. — Vertical section through the epidermis of sheep-pock. 



a. Deep layers of cells of rete Malpighii. 



V. Vesicles formed in the middle layers of rete Malpighii. 



b. Layers of " granular cells." 

 e. Stratum lucidum. 



d. Stratum corneum. 



P is near the periphery, the other end of the drawing near 

 the centre of the pustule (11, 5).
