FRANCIS' CASES OF MORBID ANATOMY. 523 



causes that can be assigned for the remarkable alteration visible in the 

 lungs. 



The lungs have been observed to be converted into a solid body re- 

 sembling the liver, and the change has been ascribed by Dr. Baillie, to 

 a " wide extended inflammation," in which a large quantity of coagula- 

 ble lymph has been extravasated into their substance :* and this 

 conversion, according to Mons. Dumas, frequently supervenes after 

 inflammatory affections of the pulmonary organs.f Earthy concretions, 

 of a considerable size, have been found in the lungs, according to Mor- 

 gagni :J Bonetus has given numerous cases of asthma and dyspnoea 

 depending upon stony-like indurations in the same organs ;$ and the 

 same elaborate writer has informed us, that in constitutions where a 

 strong predisposition to the formation of bone has existed, a portion of 

 the lungs has been converted into an osseous substance. Foreign 

 bodies of different kinds have been found in the pulmonary vessels 

 of artists of different professions, as we learn from Ramazani and 

 others,|| and the distinguished Dr. John C. Warren, of Boston, has 

 lately published the particulars of a case of organic disease in which 

 the lungs were transformed into a hard tumour, so that the thoracic 

 cavity was completely filled by a resisting solid body.1T But I have 

 searched in vain to find an instance of diseased lunffs similar to the one

 has given of the character and situation of tubercles found in these
