Dr Ramskill in his valuable paper on ‘Vertigo’ in Reynolds’ System of Medicine, mentions a variety of ver- tigo which he calls ‘essential.’ It usually occurs in persons about 30 years of age, and is probably associated with a dilated right ventricle of the heart. With the exception of the vertigo the patient feels in perfect health. I have not met with a case of this kind, but one is justified in concluding from the case recorded by Dr Ramskill, that there is some disturbance of the circula- tion, and that too little blood is sent to the brain; for he states that the area of cardiac dulness was enlarged la- terally to the right, and that the sounds were too clearly audible to the right of the sternum. Such are the facts, physiological and pathological, which, in my opinion, tend to prove that the “ proximate cause of vertigo is in the majority of cases a disordered cerebral circulation.” Prognosis. Having now discussed the various causes which induce vertigo, I proceed, in the next place, to consider its im- portance as a symptom or prognostic value.
