semble so strongly the corresponding joints of the fingers, that 

 a farther description is unnecessary. 



Of the Second and Third Joints of the Toes. 



From the shape of the surfaces of the bones composing them, 

 these are simply ginglymous articulations. They have their 

 cartilaginous incrustations, synovial membrane, and capsular 

 ligament. The under part of the latter is much thickened, and 

 forms a trochlea for the flexor tendons; on each side it is ar- 

 ranged into a lateral ligament, and above it is defective, as the 

 synovial membrane is in contact with the extensor tendon. 

 These joints also resemble so strongly the corresponding ones 

 of the fingers, that farther description is unnecessary.
