apart and the hind limbs partly flexed, head and neck extended, 

 and breathing labored. The breathing may be with constant 

 stertor, the bowels torpid and tympanitic, or loose and foetid, drop- 

 sies and haemorrhages ensue, and the patient dies in complete 

 marasmus. 



Duration. The disease may prove fatal in less than a month, 

 or it may last for three, six, or eight mouths. It is mostly fatal. 



Not inoculable. Many attempts have been made to transmit it 

 by inoculation, but in no case with success. 



Treatme7it is not successful. All hygienic measures should be 

 adopted, as for anaemia ; open air and sunshine, with protection 

 against chills ; the treatment of all complications ; iron, bitters, 

 phosphorus, arsenic in particular, electricity to the spleen, mas- 

 sage ; oxygen inhalation ; and locally, iodide of potassium or 

 mercury, generally and locally. 



I^YMPHADENOMA. HODGKIN'S DISEASE. 



Definition. Relation to leuksemia. Causes. Mainly accessory. State of 

 lymph glands, spleen, liver, bone marrow, intestine, tonsils, thymus, kid- 

 neys, liver, lungs, bronchial mucosa, pleura, pericardium, nervous system. 

 Symptoms, as in leukaemia, -with adenoid hyperplasia, but little leucocy- 

 themia. Relation to glanders. Uric acid, low density, no hippuric 

 acid. Tuberculin and mallein tests. Treatment, as in leuksemia. 

 Excision in cases not constitutional. Phosphorus, phosphide of zinc. 



Definition. Hypertrophy of the lymphatic glands with little 

 or no leucocytosis. There may further be lymphoid growths in 

 the liver, spleen, bone marrow and other organs. 



The visceral lesions in lymphadenoma do not differ in charac- 

 ter from those of leukaemia, and as it does often apparently merge 

 into that disease by the characteristic changes in the blood, it is 

 denied by many that it constitutes a separate pathological entity. 

 In his admirable monograph on leucaemia in the lower animals 

 Nocard affirms their identity. The main excuse for keeping up 

 an alleged distinction, is the frequent absence of leucocytosis, and 

 this often supervenes after the lymphadenoma has existed for 

 some time.
