Head. — Brain not examined. 



Thorax. — There are three lobes to the right lung and three to the lel't. They 

 present a reddish-brown colour, mottled with grey, and are crepitant, except at 

 the base of the lower lobe of the right, which is firm and resisting to the touch. 

 The surface of both lungs is studded with tubercles, deposited beneath the pleural 

 covering. But few are observed in the lobes of the left, or the upper lobes of 

 the right, but they are thickly agglomerated in xhelou-est lobe of the latter, which 

 is filled with them ; they are of a light yellow colour, from one line and less to 

 nearly a line in diameter, firm to the touch, and imbedded in a hepatized tissue. 

 The mucous membrane of the trachea and bronchi, traced to the smallest 

 ramifications of the latter, does not present any remarkable degree of redness, 

 being rather pale than otherwise. The bronchial glands are enlarged and tuber- 

 culous ; the largest is to the right of the trachea, and measures six lines in its 

 greatest extent; on cutting into it, a quantity of white cheesy matter makes its 

 escape. Mucous membrane of the oesophagus pale. The heart is small, measur- 

 ing one inch four lines in length, by one inch (Fr.) in breadth. The pericardium 

 contains about a teaspoonful of citron-coloured serosity. The auricles are 

 moderately distended with dark-coloured blood; a solitary tubercle about the 

 size of a pin's head is observed at the entrance of the vena cava into the right 

 auricle. 



Ahdomen. — The liver has four distinct lobes and a smaller lobule; it is of a 

 light brown colour above, dark green beneath, except in the interspaces between 

 the lobes; it presents numerous tuberculous deposits upon its upper and under 

 surface, of a larger size than are usually met with in the liver — the largest upon 

 the under surface measuring five lines in diameter : on cutting into several of 

 them they are found to be filled with tuberculous matter, of a yellowish colour 

 tinged with green. The spleen is very greatly enlarged, measuring three inches 

 three lines in length, by one and three-quarters in breadth ; it is of a pale reddish 

 colour mottled with white, having its surface throughout studded with tubercles ; 

 the central portion, on cutting into it, presents the dark-coloured appearance 

 usually observed in the spleen, and four or five nodules of tuberculous matter; 

 upon the periphery of the organ the deposit appears to exist in the form of infil- 

 tration, extending four lines within its substance at its posterior extremity. The 

 stomach does not differ materially in shape from the human, and when laid open, 

 measures four inches (Fr.) from one extremity to the other; there is a well 

 marked pylorus ; the oesophagus enters the stomach about midway between the 

 pylorus and the opposite extremity; its muscular fibres are very apparent ; it 

 contains a quantity of greenish looking fluid, having a disagreeable 

 odour; the mucous membrane is pale throughout, and does not 

 appear softened, presenting no trace whatever of inflammation ; no tubercles are
