In the large majority of cases these take place both while the patient is awake and when he is asleep. I have, unfortunately, no observations to offer as to the effects of treatment on the diurnal or nocturnal attacks in patients suffering from both. The preceding table shows the result of treatment in 15 cases in which the attacks occurred only while the patient was awake, and in 7 cases where they took place only while he was asleep. Of 15 cases of the purely diurnal form, we find that in 3 there was a total cessation of attacks during treatment, and in all the others there was diminution in their number. Of the 7 nocturnal cases, in none were the seizures entirely arrested, in 1 the attacks increased in number after treatment, and the remainder were relieved to a greater or less extent. Here, again, our numbers are small, and therefore difficult to found any definite principle upon; still there is enough to show that, contrary to the opinion expressed by most authorities, the nocturnal form of epilepsy appears to be as amenable to relief as the diurnal variety. The next point for consideration is the question whether the fact of the epilepsy being hereditary or not makes any difference in the results of treatment by the bromides. In the following table all the cases with a perfectly sound family history are placed in the first part, and the second includes those in which either epilepsy or insanity could be proved to exist in any near relation.
