t)ecorae implicated in the disease, the Inng-s may become oedematous^ 

 extravasation may occur in the intestinal canal, or effusion of serum 

 into the cavity of the chest or abdomen ; occasionally the brain becomes 

 affected. A few cases run a mild course and recovery may commence 

 in three or four days, generally, however, the outlook is unfavorable. 

 In severe cases septic poisoning is liable to occur, which soon brings 

 the case to a fatal issue. 



Pathology. — On section we find the capillaries dilated, the connective 

 tissue filled with a coagulable or coagulated lymph, and frequently we 

 may discover gangrenous spots beneath the skin or involving the skin. 

 The lymphatic glands are swollen and inflamed. Extensive extravasa- 

 tions of blood may be found imbedded between the coats of the intes- 

 tines, or excessive effusion into the substance of the lungs. 



Treatment. — Diffusible stimulants and tonics should be given from 

 the very start, regardless of fever or frequency of the pulse. Carbon- 

 ate of ammonia, 1 dram; fluid extract of red cinchona bark, 2 drams, and 

 tincture of ginger half an ounce, with half a pint of water; thin gruel or 

 milk should be given every four or six hours. Sulphate of iron in dram 

 doses may be dissolved in water and given every six hours. Chlorate 

 of potassa in 2-ounce doses may be given every eight or twelve hours. 

 When the discharges from the mouth and nose become offensive to the 

 smell, 10 drops of carbolic acid in 2 ounces of water may be given in a 

 drench, or thrown on the root of the tongue with a syringe several times 

 a day. Where the swelling is very great, incisions half an inch in 

 length penetrating the skin should be made with a sharp knife, to per- 

 mit drainage. The application of linimeuts or washes externally are of 

 no use, and if injudiciously used may do harm. Complications, when 

 they arise, must be treated with proper circumspection. 



DISEASES OF THE LYMPHATIC SYSTEM. 



The lymphatic or absorbent system is connected with the blood vas- 

 cular system, and consists of a series of tubes which absorb and convey 

 to the blood certain fluids. These tubes lead to lymphatic glands, 

 through which the fluids pass to reach the right lymphatic vein and 

 thoracic duct, both of which enter the venous system near the heart. 

 Through the excessively thin walls of the capillaries the fluid part of 

 the blood transudes, to nourish the tissues outside the capillaries ; at 

 the same time fluid passes from the tissues into the blood. The fluid, 

 after it passes into the tissues, constitutes the lymph, and acts like a 

 stream irrigating the tissue elements. Much of the surplus of this 

 lymph passes into the lymph vessels, which in their commencement can 

 hardly be treated as independent structures, since their walls are so 

 closely joined with the tissues through which they pass, being nothing 

 more than spaces in the connective tissue until they reach the larger 

 lymph vessels, which finally empty into lymph glands. These lymph 

 glands are structures so placed that the lymx)h flowing towards the
