THE NERVOUS SYSTEM. 107 



forming a diagnosis or opinion of disease, and which, in many 

 obscure cases will enable or aid the physician much better to dis- 

 criminate between different diseases. Some persons expect or 

 think that a doctor must know everything, and tell their complaints 

 perhaps without asking them a single question. This method will, 

 in many cases, impart this secret. Generally, however, it is neces- 

 sary to form our opinion by other means of investigation. 



Sherwood states as follows, in a treatise called his MOTIVE 

 POWER : These forces point to the disease in every other part 

 of the system that may be tuberculated, in the most arbitrary man- 

 ner, as in these cases without any regard to the classification of 

 nosologists, or the pedantic theories of the schools. 



In tubercula of the stomach, and its immediate appendages, 

 called dyspepsia, pressure between the 2d, 3d and 4th, and some- 

 times 5th and 6th dorsal spaces, (counting from the last or large 

 joint of the neck,) produces pain. 



In tubercula of the liver, called chronic inflammation of the liver, 

 or liver complaint, pain is produced by pressing on the right side, 

 between the 7th and 8th, and 8th and 9th dorsal spaces, and 

 directly opposite to the lower part of the right shoulder blade. 



In tubercula of the spleen, pain is produced by pressure on the 

 left side of the last named, or 7th and 8th, and 8th and 9th 

 dorsal spaces, and opposite to the lower part of the left shoulder 

 blade. 



In tubercula of the right kidney, pain is produced by pressure on 

 the right side of the space between the 12th or last dorsal, and first 

 lumbar vertebra, and in tubercula of the left kidney, pain is pro- 

 duced by pressure on the left side of the 12th dorsal and first 

 lumbar. 



In tubercula of the uterus, called leucorrhoea, cholorosis, ame- 

 norhoea, and menorrhagia, pain is produced by pressure, between 

 all the joints of the back, except the 1st and 2d. 



In tubercula of the genital organs, pain is produced by pressure, 

 between the 5th or last lumbar space, and the os-coxyx. 



This pain, produced by pressure, is always more or less severe, 

 in proportion to the severity of the disease. If there is but little 

 disease, the pressure will produce but little pain ; but if there is 

 much disease, the pain will be severe.* 



The disease, in whatever organ it may be, is always either active 

 or passive, and if it is active, when such pressure is made, this pain, 

 * Reason, a part of greater sensibility, sympathizing with one of less.
