normal, hut an excess of fluid injected and none excreted may so over- 

 tax the heart, already weak, as to cause sudden death. 



A red cell count should be done every other day, and the move- 

 ments of the patient, such as sitting up and using the bed-pan, &c., 

 must be controlled thereby. To attempt to Avalk too early may cause 

 sudden death. 



Exercises should be graduated and permitted according to the red 

 cell regeneration, this being a much safer guide than the feelings of 

 the patient or the temperature chart. One patient mav regenerate in 

 much less time than another. 



FAVISM. 

 DEFINITION. 



An acute febrile anaemia with icterus and haemoglobinuria. 



DISTRIBUTION. 



It occurs in Sardinia, and perhaps other Mediterranean ports. 



ETIOLOGY. 



Sufferers blame fresh beans, raw or cooked, and even the smell of 

 bean flowers when in blossom. It usually occurs in the season when 

 the bean ripens. 



SYMPTOMATOLOGY. 



A few hours after ingestion of beans or exposure to the scent of 

 the flowers an acute febrile anaemia develops, and the red cells may be 

 rapidly reduced to 2,000,000 per c.mm. and the hb. to 20 per cent. 

 There is icterus; the liver may be tender to pressure; the urine contains 

 free hb., urobilin and indican. The blood-serum, however, is clear 

 and does not contain any hb. 



Sometimes there is bilious vomiting and diarrhoea. 



Children usually die, adults recover. 



The blood quickly regenerates. 



Malaria and quinine can be excluded from the causative factors. 



Little is known about it at present. 



TREATMENT. 



As for hiemoglobinuria. 



HEAT SYNCOPE AND HEAT STROKE. 



Of this disease there are two groups, which may be classified 

 thus : — 



(i) Heat syncope, an exhaustion with little or no fever, but with 

 some cardiac failure as a rule.
