248 SPECIAL HISTOLOGY. 



curves of their fibrils, which correspond with each other 

 throughout the fasciculus; this appearance is destroyed when 

 the tendon is forcibly stretched, and merely indicates its 

 innate elasticity, which conies into play in the relaxed con- 

 dition. 



[The primary tendinous fasciculi, according to Donders and 

 Moleschott, are seen in transverse sections treated with potass ; 

 this reagent, according to them, separates the secondary 

 fasciculi into smaller ones, each of which consists of from 5 to 10 

 primitive fasciculi. In moistened transverse sections of dried 

 tendon of man and the mammalia, I can very distinctly 

 recognise the primitive fasciculi, although they have extremely 

 delicate outlines. The appearance thus obtained affords an 

 indistinct image of that presented in a transverse section of 

 muscle. Even the very fibrils are, in this way, rendered distinct, 

 a circumstance which appears to me of the greatest importance. 

 When a transverse, not a longitudinal section of tendon 

 moistened with water or acetic acid is examined, there will be 

 observed in all the secondary fasciculi, or in the primary when 

 they can be distinguished, if not in all, yet in most cases, an 

 extremely regular and minute punctation, nearly like that of 

 the muscular fasciculi (fig. 90), only not quite so distinct. The 

 apparent granules are pale, round, of the same diameter as the 

 tendinous fibrils which are obtained in other wavs, and can be 

 explained in no other manner than as being the transverse 

 sections of such fibrils. These facts, better than any other, 

 contradict Reichert's view, according to which, the tendinous 

 tissue is composed of a homogeneous substance. (Vid. § 24, 

 note).] 



§ 81. 



Connections of the Tendons with other parts. — The tendons are 

 connected on the one side with the muscles, and on the other 

 with the various parts moved by the muscles. Even by the 

 naked eye, it may be seen, that the former connection is effected, 

 in the one case, in such a way that the tendon and muscle are 

 continued into each other rectilinearly, and in the other so 

 that the muscular fibres, with rounded extremities, join the 

 borders and surfaces of the tendons and aponeuroses at an acute
