very simple matter, because then they would be exactly opposite types of insanity.

One of these days, J. O., because of a visual hallucination, a dream, vivid emotional experience, reading of some passage in the Bible or some fortuitious circum stances, will believe himself to be a prophet, the blessed of Heaven, or a Christ. His emotions will become pleasurable, ecstatic.

Gentlemen, before introducing some cases of paranoia, just a few words. Paranoia is a form of disease occurring in one of a congenitally defective nervous or ganization, which manifests itself by logical or systemized delusions of persecution and self-exaltation without excitation of ideas or emotions, impairment of memory or volition.

There is an infinite variety of types of paranoia. The one I now introduce to you has delusions of both perse. cution and grandeur. This case is fully developed. Gentlemen, this is H. K., a young man with a bright, receptive mind, aged 24, admitted only a few days ago; duration of disease four years; always been eccentric. I have no history as to heredity. You will notice he has a poorly developed head, the circumference of which is large enough, being twenty-two and one-half inches, but the antero-posterior diameter is out of proportion to the lateral. His frontal development is deficient and out of proportion to the occipital.

Now, Professor, tell the gentlemen why you think you are persecuted by the watches? Professor: "Well, you see it is like this: the witches have a power over me and will not give me a chance to marry because they fear I will start a new, superior race of people who will be able to cope with and overpower them."

Gentlemen, this case well illustrates one thing Dr. Runge, of St. Louis, told you, namely: One suffering from paranoia does not usually drift into dementia as

The patient has the delusion that he is a second Christ, that he has a mission to perform as yet not known, that will be revealed later. He is egotistical and thinks he is persecuted by his mother and brother who are jealous of his superior talents and genius, and would much prefer these blessings had been bestowed upon a brother who is now attending the University of Michigan. His delusions are systematized and limited, do the other forms of insanity; at least, if he does, the which should be the case in paranoia. On all other subjects he speaks intelligently. This young man other wise is really bright. He completed his education at one of our State Normals.

The next case of paranoia is H. F., whom we call "Professor," an appellation of which he is very proud. He is 47 years of age and has been here twenty-five years. He was a school teacher. His father was a neurotic.

"Professor" has fixed, egotistical and persecutive delusions. I will ask him to tell you what he thinks of himself. Professor: "I am the smartest man in the world and as superior to the ordinary man as man is to the lower animals. I am destined to be the progenitor of a new race, just as Adam was of the weople who now inhabit this world, but I have always been persecuted by the witches."

I will now ask the "Professor" why he thinks he is persecuted by the witches. I do this to illustrate a systematized delusion, one that is explained and defined. In acute mania or paresis the delusions are unsystematized, and if I ask such a patient the question, "Why do you think you own the world," etc., he can not give me any plausible reason.

progress is slow. This man has been insane twenty-five years and is just the same now as when admitted, so far as mental ability is concerned.

He

This is H. T., a different type from the preceding ones. This is erotomania, so called, but it is only a form of paranoia. His age is 31, occupation teacher, paternal aunt insane and father intemperate. He has been bere and at Jacksonville a number of years. is one of those fellows you often see whose egotism finds vent in aspiring to the hand and love of a lady far above him socially and financially. They never become discouraged but think and dream of their loved ones constantly. They are often given to poetry. This man writes letters and poetry to Helen Gould, which, of course, we never send.

If he has any delusions of persecution I have never been able to detect them. Perhaps earlier he did and has lost them, for it is sometimes the case that the delusions of persecution become affected. It was not so in "Professor's" case, however, he having retained his twenty-five years.

This is W. R., aged 29, admitted eighteen months ago, always considered peculiar. His mother was insane. He has delusions of persecution, differing only
