the result of tubercular disease, spontaneously cured. The leffc 

 kidney is about twice the size of an ordinary one, but seems 

 to be normal in structure. No doubt the enlargement has 

 followed the increased demand upon its functions from the 

 destruction of the other kidney. G. C. 3229.

FROM IRRITATION OF VARIOUS KINDS. 



1. 9. Periostitic Bone Formation near Septic Necrosis. — 



Lower portion of the stump of a femur, in which there has 

 been necrosis — macerated and dried. 



The patient, a girl ast. 15 years, had suffered amputation through 

 the thigh some time before the specimen was obtained. 



The lower end of the bone shows one distinct necrosis, 

 with a smaller spicule of necrosis near it. The end of the 

 medullary cavity has been closed in with bone, and a complete 

 shell of periosteal bone surrounds the original shaft. This 

 shell is thick at its lower end and along the anterior aspect 

 of the femur. G. C. 3138. 



1. 10. Thickening- of Ribs from Empyema.— Section of two 



ribs, with a portion of a greatly thickened pleura, showing the 

 above changes. 



In consequence of prolonged empyema the pleura has been 

 greatly thickeiied, and along Avith this a considerable growth 

 of bone has taken place on the surface of the ribs next the 

 pleura. G. C. 3074.
