All the maxillary movements are reproduced by the 

 wire, the upright end of which indicates by its inter- 

 sections on the photograph the centres of articular 

 movement. 



The applications of chronophotography for analyzing 

 such movements as occur within the field of the micro- 

 scope will probably be of great importance. Our 

 efforts in this direction will be recounted in the follow- 

 ing chapter.
