An attempt was made in twenty-two cases to ascertain whether, in women, the age at which the epileptic attacks began had any relation to the period at which the catamenia commenced, with the following results:-- Average age at which attacks began 14.6 years Average age at which catamenia began 14.6 years This shows singularly enough exactly the same figures, and serves to point out, that in women, the earliest manifestation of puberty is a decided exciting cause for epileptic attacks. It must however be stated that, in the female epileptics, the attacks commenced before the age of puberty in 16.9 per cent. of their numbers. Of the 8.7 per cent. of cases included under the term "diseases of the nervous system," the epilepsy was associated with hemiplegia in all. SYMPTOMATOLOGY. In a hundred unselected cases of epilepsy there were-- Epilepsia gravior in 62 per cent. Epilepsia mitior in 10 per cent. Epilepsia gravior and mitior in 28 per cent. 1.--EPILEPSIA GRAVIOR. _Premonitory Symptoms._--In the cases in which epilepsia gravior was present there were-- No premonitory symptoms in 34.4 per cent. Premonitory symptoms in 65.5 per cent. Of those cases in which there were symptoms premonitory to the attack, there were-- General premonitory symptoms in 47.4 per cent. Special Auræ in 72.8 per cent. By _general premonitory_ symptoms are understood those morbid conditions lasting for some hours or days before each attack, and of the cases under consideration in which these were present, the following is an analysis:-- Prolonged vertigo in 46.4 per cent. Headache in 21.4 per cent. Nervousness in 14.2 per cent. Drowsiness in 3.5 per cent. Faintness in 3.5 per cent. Depression of spirits in 3.5 per cent. Cramps in 3.5 per cent. Numbness of extremities in 3.5 per cent. Of the cases in which a _special aura_ preceded the attack, the details are as follows (the special symptom in each case being sudden):--
