an injection the glycsemia was found often to have dropped to the 

 original content. 



There can be no doubt that magnesium sulphate produces 

 considerable hyperglycaemia which is not due to asphyxia; it is 

 produced in some way specifically by the magnesium salt. Sodium 

 sulphate does not affect the normal glycaemia. 



It is a noteworthy fact that the glycosuria was very little 

 marked and far under proportion to the hyperglycaemia. Gly- 

 cosuria was often entirely absent and when present it never reached 

 even Yl per cent. The intravenous injection of magnesium sul- 

 phate also produced very little diuresis.
