108 ANATOMY AND PHYSIOLOGY. 



on every repetition of the pressure, will dart into the diseased organ, 

 with a force or violence, proportioned to the intensity of the disease. 



ANOTHER BUT SIMILAR FIGURE TO LEARN DISEASE. 



Acute and chronic tubercula, or inflammatory, and chronic 

 diseases of the serous membranes, or serous surfaces of the body, 

 organs or limbs, including the skin and facia of the muscles, is 

 easily and invariably distinguished by pain more or less severe (in 

 proportion to the intensity of the disease), produced by pressure on 

 the ganglions of the spinal nerves, in the intervertebral spaces along 

 each side of the spine without any previous knowledge of the case 

 no matter what name may have been given to the disease by phy- 

 sicians, nosologists, or other medical writers. 



Ganglions of the Spinal Nerves in the intervertebral spaces. 



There are 7 cervical vertebrae, C ; 12 dorsal, D ; and 5 lumbar, L ; these vertebrae, with the os 

 coccyx, m, constitute the spinal column. The spinal cord passes from the brain along the round 

 cavity through the middle of the vertebras, and the above ganglions are connected with it by the 

 sympathetic nerves, which are also connected with the organs and muscles. 



Press on the sides of the 1st cervical vertebra to find symptoms 

 of tubercula of the head of the brain, throat, nose, eyes, or ears. 



Press on the sides of the 2, 3, 4, 5, 6, and 7 cervical to find tu- 

 bercula of the muscles (Rheumatism), or of the vertebra, or of the 

 joints of the limbs white swellings, &c.
