they would maintain the muse, levator palpebrae in position, and 

 thereby sustain its leverage. Each part would of itself be capable 

 of di-agging the muse, levator palpebrea more or less to its ow^n 

 side, and thus drag the medial part of the eye-lid up- and inwards, 

 resp. the lateral part up- and outwards. 



The connection to Tenon's capsule would rendei' an action on it 

 possible and consequently assist in the leverage of tiie muse, levator 

 palpebrae. Lastly, in consequence of the .strain of the whole muse, 

 transversus, the broad, lateral tendinous expansion would perhaps 

 press the lachiymal gland tighter against the supeiior orbital wall 

 and compress it more. 



Macalistkr ') believed lliat the muse. Iransversus was a displaced, 

 deep slip of the pars palpebralis of the muse, orbicularis oculi. 

 However, in my judgment the connection between the muse, trans- 

 versus and the muse, levator palpebrae is too close for me to share 

 his view. 



If Macalistkr's view were correct, it would follow that the fibres 

 would extend beyond the muse, levator palpebrae. But, as noted 

 before, in our case, and in Bochdalkk's case also, not a single 

 muscular fibre of the muse, transversus runs beyond the muse, 

 levator palpebrae; in our ease the transversus-fibres pass chietly 

 beneath the muse, levator. This experience is supported by Macalistkr's 

 finding that he saw deejj slips of the muse, orbicularis oculi coursing 

 in about the same place where we found the muse, transversus, 

 and that these fibres ever occurred outside the muse, levator palpebrae.
