Now when comparing tlie case discussed just now with Bochdalek's 

 finding-, remarkable differences come to llie front. 



BocHDALEK saw the muse, transversus continuous with the muse, 

 graeillimns, which has been described before by Ai,binus'), and was 

 closely related to the muse. Iransversus. The said muse, graeillimns 

 is absent in our case, which, therefore, is the first ease in which 

 the muse, trausversus occurs uncomplicated with other abnormal 



muscles. 



Furthermore Boohdalkk calls attention to the fact that a close 

 relationship existed between the muse, transversus found by him 

 and the musc.-levator palpebrae, in such a sense that most fibres of 

 the two muscles were blended inseparably, and that others bend 

 round partly anteriorly, partly posteriorly, towards the medial bor- 

 der of the muse, levator palpebrae, while blending- with the latter; 

 while a considerable part of the muse, transversus pierced through 

 the muse, levator and ran to the lateral orbital wall. Now when 

 drawing a parallel between this description and ours, it is evident 

 that a close connection between the muse, transversus and the muse, 

 levator palpebrae is entirely out of the question here. 



First of all there is in our case no bending forward of fibres of 

 the muse, transversus. Secondly we do not note an inseparable 

 blending of the fibres of the muse, transversus and the muse, levator 

 palpebrae. Thirdly in our ease there is, strictly speaking, no piercing 

 of the muse, levator palpebrae by the muse, transversus, because 

 the muse, transversus runs almost entirely below the muse, levator 

 palpebrae and only few slender muscle fascicles of the muse, levator 

 pass below the muse, transversus, and that only in part. 



The principal points of agreeinent are the connection with the 

 lower sheet of the muse, levator palpebrae and with Tenon's cap- 

 sule, and the relation to the lachrymal gland. 



As regards the innervation of the muse, transversus, we are sorry 

 to say nothing can be recorded. When the muscle was found, the 

 upper fat-layer together with the nerves had on both sides got lost 

 in the preparation. Bochdai,ek only reports an innervation of his 

 left muse, transversus by very tiny branches of the nn. frontalis 

 and lacrimalis. 



The function of the muse, transversus orbitae is naturally difficult 

 to ascertain. Bochdalek considered the muse, transversus to be a 

 complex muse, transversus internus and externns. When co-operating 

 from the two insertion i)oints (internal and external orbital w^all),
