Academy of Sciences, Sept, 12, — M. Duchartre in the 

 chair. — On the heat of combustion of glycoiic acid, by M, 

 Berthelot. — Note on several new facts relating to the physiology 

 of epilepsy, by M. Brown-Sequard. If by epilepsy is understood 

 a group of reflex convulsive movements, it is invariably induced 

 in guinea-pigs by cutting one of the sciatic nerves. If, however, 

 the section has been made in the lower part of the thigh, the 

 convulsive manifestations often are confined to the side of the 

 lesion, and the animal retains consciousness. This is due to 

 the regeneration of the nerve, which takes place rapidly, and 

 which stops the development of the disease, or even cures it 

 altogether. Generally, the greater the number of nerve fibres 

 severed, the stronger is the tendency towards epileptic fits. A set 

 of absolutely decisive facts have shovvn that a violent attack can 

 be produced which is due to the spinal marrow alone. This 

 epilepsy as displayed in guinea pigs is absolutely equivalent to 

 the idiopathic or cerebral disease in man. Clinical as
