Barring-ton made mention of crooked perch and trout in Wales. 

 Howes said that in the curvature of the spine there was no co- 

 ossification of the vertebrae, but the neural spines of certain of the 

 vertebrae bore synostotic enlargements indicative of preceding frac- 

 ture. He regarded the synostoses, compression and sinuation, as 

 congenital, but that the muscular rather than the skeletal system 

 had been at fault, was largely proved by the fact that there was no 

 marked falling-off in either the bulk or the density of the latter 

 where disturbances occurred, and the most logical determining cause 

 seemed to be that of an inequality of development either in bulk or 

 elasticity of certain muscles, those affected having either, as it were, 

 lagged behind the skeleton or become fixed in a state of toxic 

 contraction. 



Hofer says that the spinal curvature is caused by the growth of a 

 single vertebra. The cause is possibly infection in the periosteum 

 of the vertebra.
