258 THE NATURE AND TREATMENT OF 



latter ; how a diseased condition of the internal mucous mem- 

 bi-ane reacts on the common integument, and vice versa. Even 

 in the osseous structures, the law of sympathy prevails. A dis- 

 ease in the upper extremity of the bone gives rise to sympathetic 

 pain at the opposite extremity. (Consult Hooper and Cooper 

 on the hip-joint lameness). And as regards the muscles and 

 tendons, there exists a very marked sympathy, although in the 

 mind of pathologists this is not strange, for anatomically con- 

 sidered, the tendons are neither more nor less than tendinous 

 terminations of muscles. 



Puncture of a tendon is often followed by great derangement 

 of the nervous system, and other pathological conditions, not 

 unfrequently ending in trismus — lockjaw. This is owing to 

 the same law of sympathetic association just alluded to. There 

 is, therefore, a tendency in certain organs to become deranged 

 or diseased in consequence of a malady locating in others, al- 

 though they may not always be indentical in function.
