Fig. 6. — Nerve termination from neuro-tendinous end-organ of turtle, from 

 preparation fixed in ammonium molybdate, teased and mounted in balsam. 

 Leitz No. 7 objective ; No. 2 eye-piece ; reduced in figure to »^ the size of 

 drawing. 



P^S- 7- — Longitudinal section of neuro-tendinous end-organ in fascia-like 

 tendon. Shows relative position of nerve ending in tendon. Tissue fixed in 

 ammonium molybdate, sectioned and counterstained in alum carmine. Leitz 

 No. 7 objective ; No. 2 eye-piece. Figure reduced to 2.5 of the size of 

 drawing. 



Fig: 8. Preparation made as in Fig. 7. Leitz No. 7 objective ; No. 2 eye- 

 piece. Figure reduced to % the size of the drawing. 



Figs, g, 10 and 11. — Cross sections of neuro-tendinous end-organs of turtle. 

 Tissue fixed in ammonium molybdate, sectioned and counterstained in alum 

 carmine. Fig. 11 shows an imperfectly encapsulated neuro-tendinous end-or- 

 gan. Leitz 1-12 oil immersion ; No. 2 eye-piece. All reduced to ^ of size of 

 drawing. 



PLATE XV. Bird[T)o\t). 



Figures in Plate XV are from neuro-tendinous end-organs obtained from the 

 tendons of the wings of doves. 



//i,^. 12. — Small neuro-tendinous end-organ, with no, or imperfectly devel- 

 oped capsule, compressed under cover-glass to bring out more cleaj-ly the gen- 

 eral arrangement of nerve branches and terminations. Leitz No, 7 objective ; 

 No. 2 eye-piece. Figure ^ the size of drawing. 



Figs. /J, 14 and i^. — Neuro-tendinous end-organs of dove, showing differ- 

 ence in size and shape and complexity of nerve terminations. Leitz No. 7 ob- 

 jective ; No. 2 eye-piece. Figure 13 reduced to ^, Figs. 14 and 15 to ]4. the 

 size of drawings. 



Figs. lb and 17. — Longitudinal sections of neuro-tendinous end-organs of 

 dove ; from sections made by fixing tissue in ammonium molybdate, sectioning 

 and staining in alum carmine. Show relation of end-organs to the tendon and 

 muscular fibers. Leitz No. 7 objective ; No. 2 eye piece. Figures reduced to 

 y^ the size of drawings. 



Figs. 18 and ig. — Cross sections of neuro-tendinous end-organs of doves. 

 Sections prepared as for figures 16 and 17. Leitz 1-12 oil immersion; No. 2 

 eye-piece. Figures yi, the the size of drawings. 



PLATE XVI. Mammalia. 



Fig. 20. — Neuro-tendinous end-organs from interossei muscles of posterior 

 extremity of a dog. From preparation fixed in ammonium molybdate, teased 

 and mounted in balsam. In this figure, the shape and general structure of this 

 end-organ, as found m the dog, are well reproduced. Leitz No. 7 objective ; 

 No. 2 eye-piece. Figure reduced to y^ the size of drawing. 



Fig. 21, — Neuro tendinous end-organ of cat. Leitz No. 7 objective ; No. 

 2 eye-piece. Figure reduced to »^ the size of drawing. 



Fig. 22. — Neuro-tendinous end-organ of rabbit. Leitz No. 7 objective; 

 No. 2 eye-piece. Figure reduced to «^ size of drawing.
