Tendon. 67 



Make a preparation of Newt's mesentery in 5 per 

 cent, chromate of ammonia (page 13), and double stain 

 with picro-carmine and logwood (page 36). In this 

 preparation very large branched corpuscles will be seen 

 having the hyalin ground plate stained with logwood ; 

 these make most beautiful objects for examination with 

 high powers. 



The corneal corpuscles will be mentioned in another 

 place. 



TENDON. 



To show the tendon cells which lie in the interfasci- 

 cular lymph spaces, take a young mouse just killed and 

 remove the skin of the tail, then with the fore- finger 

 nail separate two of the caudal vertebrae and forcibly 

 remove the distal portion. Several white threads will 

 be left, these are the tendons. Take a small bit of one 

 of the finest and place it in slightly acidulated water 

 for a short time, then remove to half per cent, gold 

 solution, let it remain about twenty minutes. Then 

 place it in distilled water, which must be changed once 

 or twice, until it becomes a bronze colour. Take a 

 small bit and place it in a drop of glycerine on a slide, 

 and separate it into as many fibrils as possible. Cover 

 and examine. 



Take the tail of a young rat and prepare it in gold 

 chloride (page 14). Make .transverse sections and 

 double or treble stain them. The tendon cells will be 

 seen darkly stained, with the gold lying between the 

 bundles of fibrous tissue forming the tendons. 



Tendon should also be examined in the fresh state,
