DESCRIPTION OF FIGURES. 



All figures were sketched, at the level of the table, with the aid of the 

 camera lucida and are from preparations stained in methylen-blue. All figures 

 giving surface views of neuro-tendinous end-organs, unless otherwise stated, 

 were drawn from preparations fixed in a saturated solution of ammonium pi- 

 crate, cleared, teased and mounted in ammonium-picrate-glycerine. 



Reference Letters. 



c. — capsule of neuro-tendinous end-organs. 

 m. — striated muscle fibers. 

 mn. — medullated nerve fibers. 

 nR. — nodes of Ranvier. 

 /. — tendon. 



PLATE XIII. Amphibia. 



Figs. I and 2. — Terminations of nerve fibers in neuro-tendinous end-organs 

 of frog, from tibialis posticus. Only the nerve fiber and its terminal branches 

 reproduced. Leitz No. 7 objective ; No. 2 eye-piece. Figure 1, reduced to ^ 

 original size ; figure 2, y^ original size. 



Fig. J. -A portion of longitudinal section of neuro-tendinous end-organ of 

 frog, stained in methylen blue, fixed in ammonium molybdate, sectioned and 

 eounterstained in alum carmine. Leitz I-I2 oil immersion ; No. 2 eye-piece. 

 Reduced to 3^. 



Fig. 4. — Cross section of neuro-tendinous end organ of frogi Prepared as 

 in Fig. 3. Leitz 1-12 oil immersion; No. 2 eye-piece. Reduced to ^. 



PL.\TE XIV. Reptilia (Emys meleagaris). 



Fig. J. — Nerve fiber with terminal branch and irregular end-disks from ten- 

 don taken from posterior extremity of turtle. Preparation was compressed be- 

 fore sketching to bring out more clearly the general distribution of the nerve 

 branches and their terminations, Leitz No. 7 objective; No. 2 eye-piece. Re- 

 duced in figure to ^ the size of drawing.
