The demonstrations will require drawings of skeletons 

 in different attitudes and points of view ; and it is pre- 

 sumed the whole length skeleton will be the only whole 

 length jigure required; as all the remaining demonstra- 

 tions may be made on drawings of detached parts of the 

 upper divisions of the figure. The skeleton may be 

 shown collectively, and in parts. The several modes in 

 which the parts of the skeleton are articulated or joined 

 together, will follow next in the order of natural succes- 

 sion. 



DEMONSTRATION. 



The articulations, or joints their construction and 

 motions; the cartilages and ligaments on draw- 

 ings and on engravings. 



The physiology of the skeleton will conclude the first 

 part. 



II. The prop-work of the fabric being finished, the 

 next step will be to exhibit collectively and separately 

 the instruments by which it is put in motion. 



DEMONSTRATION. 



Simple uncoloured outlines of the muscles of the head, 

 neck, and of the upper extremities. The mechanism 

 of the lower extremities bears such resemblance to 

 the upper, that little need be said concerning them. 



Physiology of the muscles, muscular motion will close 

 the second part. 



III. THE BRAIN, the place of residence of the 

 mind, with all in its appendages necessary for the union 

 of spirit or soul and body; the NERVES, her instruments 

 for governing and acting upon the body, may be next 

 produced. Demonstration, the brain and the whole 

 nervous system, which may admit of great variety of illus- 

 tration on drawings and on engravings.
