pancreas. And yet this organ is involved in nearly all 

 diseases of the liver, in specific fevers due to a poison in 

 the blood, and in disorders of the lymphatic vessels. Ob- 

 structed circulation through the liver sends the blood 

 back on this organ and over-distends it almost to rupture. 



Advanced tuberculosis and cancer rarely faU to show 

 secondary deposits here. Glanders sometimes shows the 

 same tendency. Anthrax and anthracoid affections and, 

 to a less extent, other specific fevers, lead to enlargement 

 and even rupture of the spleen, in connection with the 

 long retention of the blood and disease poisons in its ve- 

 nous cavities. Of particular diseases the spleen suffers 

 from wasting in starved animals, from extraordinary in- 

 crease in the highly fed, and from changes of structure 

 such as alandular degeneration and enlargement (lymphade- 

 ncma). tfOt^ of these diseases, and notably the latter, 

 are associated with an excess of white globules in the 

 blood, (huJccemiaJ which condition revealed by the micro- 

 scope may assist in diagnosis. 



We can do little for these affections besides giving at- 

 tention to the general health, by tonics and a sound hy- 

 ^eue.
