respects, and says that it occurs oftenest in the coats of the 

 stomach about its cardiac extremity : he thinks round 

 form is caused by the action of the muscular coat, which re- 

 tracts on all sides after it is perforated. Cruveilhier and Mohr 

 think the ulcer consists in inflammation and ulceration of 

 the glands of the stomach ; Rokitansky, in an acute red soft- 

 ening, or a sloughing, which kills the mucous membrane ; 

 Siebert calls attention to the connexion between these perfor- 

 ating ulcers and diseases of the brain and spinal column. Ferity 

 philitis, or abscess of the iliac fossa on the right side, happens 

 occasionally, according to Grisolle, as a consequence of inflam- 

 mation of the ccecum or of the vermiform appendix. It occurs 

 commonly in men, in women chiefly after child-birth, when 

 they do not suckle. The pain attending it is at times felt in 

 distant parts, in the whole lower part of the body, and in the 

 groins : from pressure of the pus on the nerves, the legs be- 

 come benumbed or the seat of deep lancinating pains : pres- 

 sure on the veins causes oedema : suppuration generally super- 

 venes, and the pus makes its way out through the skin, the 

 alimentary canal, or the bladder. Riedel has met with a case 

 of a communication between the ccecum and ileum through 

 the vermiform appendix. 



k. Salivary glands, — Of inflammation of them, Cruveilhier 

 distinguishes three varieties : — 1st, inflammation of the excre- 

 tory ducts and the granules of the gland (which most com- 

 monly extends from the centre to the periphery) ; 2nd, of the 

 interstitial cellular tissue ; 3rd, of their veins. He never saw 

 suppuration of the parotid without simultaneous gangrene, 

 a fact explained, according to him, by the close texture of the 

 gland. 



/. Liver.— Becquerel considers cirrhosis, or granulated 

 liver, to be a hypertrophy of the yellow substance, caused (in 

 consequence of habitual congestion) by the infiltration of a 

 plastic material, which afterwards contracts, and thus causes 

 atrophy. According to Hallman, there are imbedded in a
