From these figures we find that in 34.4 per cent. of the cases of epilepsia gravior there are no special symptoms announcing the seizure, which takes place without warning of any kind; and it is especially in such cases that patients in falling, seriously injure themselves. In 65.5 per cent. there are premonitory symptoms of some kind, which indicate often many hours before the approach of an attack. Of these last 47.4 per cent. are of a general character, and in no less than 72.8 per cent. is there a distinct special aura, which in 25.4 per cent. alone precede the attack, the remainder being associated with the general premonitory symptoms.

Symptoms of the Attack.—In the cases of epilepsia gravior there were complete loss of consciousness with convulsions, lasting from five to ten minutes, and occurring at intervals, leaving no question as to the true nature of the disease, and all doubtful examples have been excluded from this collection. Attempts were made to form an analysis of the different symptoms constituting the paroxysm, but with indifferent success, and these are not here reproduced, because they are not sufficiently accurate for scientific purposes. The patient himself can give no account of what takes place. The friends around do not look upon the phenomena of the attack with the critical and philosophic eye of the physician; hence any information from them as to the part convulsed, the colour of the skin, the duration of the seizure, and so on, is extremely vague and untrustworthy. The number of cases personally observed actually during attacks is too limited to warrant any generalizations. There is, however, one important point which can be accurately demonstrated—namely, whether or not the tongue is bitten, and in the cases under observation

The tongue was bitten in68.8 per cent.
The tongue was not bitten in31.2 per cent.

Frequency of Attacks.—Only a general average of the number of attacks can be made; and in the present series the following gives an idea of the frequency of seizures in different individuals.

Average of one or more attacks per day in8.8 per cent.
Average of one or more attacks per week in31.1 per cent.
Average of one or more attacks per month in32.2 per cent.
Average of one or more attacks per year in15.5 per cent.
At longer or more irregular intervals in12.2 per cent.

This roughly indicates that, in the majority of cases, attacks of epilepsia gravior occur one or more times weekly or monthly. Under the last series, of attacks taking place at longer and more irregular intervals than a year, are included those cases where a few only have occurred during the lifetime of the patients.

Regularity of Attacks.—Many epileptics are attacked at regular intervals, sometimes on the same day or even hour; while others are afflicted at any time, day or night. The following indicate the proportion:—
