Another form of ending to which Sachs assigns a second- 

 ary position was found in the tendons of the frog. As the de- 

 scription given by him approached one which may now be 

 given of these endings as found in the frog, we give it in his 

 own words : " Es finden sich namlich einzelne Fasern, nament- 

 lich in Froschsehnen, welche pinsel-formig in eine Anzahl sehr 

 feiner, blasser Aestchen ausstrahlen. Die letzteren sind mit 

 wenigen spindleformigen Kernen versehen, und verlaufen iiber 

 grossere Strecken des Praparates ohne sich weiter zu verasteln. 

 Sie endigen wahrscheinlich Spitz." 



To the nerves terminating in tendon, Sachs ascribes a sen- 

 sory function, believing that they subserve the muscle sense, 



Gemt's investigations on nerve-endings in connective tissue 

 did not materially further our knowledge concerning this ques- 

 tion. His investigations on the nerve endings in tendons of 

 mammalia gave negative results. Concerning the nerve end- 

 ings in tendons of frogs and lizards, he says: "From the 

 several medullated branches of the nerves going to tendon, 

 there proceed varicose fibers of variable size, which branch often 

 and now and then anastomose ; these end free in the tissues 

 without any terminal enlargement." 



Golgi's observations on this subject were much more com- 

 prehensive and must be regarded as fundamental to our more 

 accurate knowledge of the special sensory end-organs in tendon, 

 especially with reference to those found among the higher ver- 

 tebrates. His own summary of the literature preceding his 

 publication may be here inserted, as it states comprehensively 

 the status of the question under consideration at the time he 

 began his work. He says : We may say, therefore, that 

 while we possess a fairly detailed knowledge concerning the 

 nerves ending in the tendons of lower vertebrates (frog and liz- 

 ard), concerning the problem of the connection of the nerves 

 with the tendons of higher vertebrates in general and man in 

 particular, our knowlege has not been materially advanced since 

 KoUiker stated that he had observed in the tendons of small
