" GRATEFUL HOSPITAL PATIENTS. THERE is plenty of abuse of the hospitals by patients who avail themselves of their open doors and their gratuitous terms. Probably it would be found that such abuse is more common in those who have no claim to be relieved gratuit- ously. It is pleasant to report an instance of gratitude. The Evening iYe7vs publishes a letter by Thomas Tovey narrating how late one night, in circumstances of agony, he repaired to St. Thomas’s Hospital and had all his wants respected and his agony relieved by a skilful operation. The consideration for his wants was so refined that when "the kind Sister of the Clayton ward " found he was a veteran smoker she " had him wrapped in blankets and wheeled into a smoking-room. " We are not blind and undiscriminating admirers of our great voluntary hospitals. But they are too splendid an achieve- ment of the voluntary principle to be lightly left to one-sided criticism. The correction of the abuses of the out-patient department and of the admission of those who can afford reasonable fees outside would leave them the finest institu- tions of civilisation under Christian conditions.

EPILEPSY AND ERRORS OF REFRACTION. IN the current number of Brain Mr. Work Dodd deals with the question of the relationship between epilepsy and errors of refraction. An analysis is given of the results of examination of the eyes in 100 cases of true epilepsy, and a comparison is made with the refractions obtaining in appar- ently normal eyes. Of simple hypermetropia there were 28 cases per cent. less in the epileptic than in the apparently normal class. Of astigmatism of all kinds there were 26 cases per cent. more in the epileptic division than in the normal one, this difference being in great part made up by the in- crease in epileptics of compound hypermetropic astigmatism -viz., eighteen cases more than the normal percentage. If the difference of the 26 cases per cent. of total astigmatism in the epileptic be added to 42 cases per cent. of the simple hypermetropia of the normal class, the result comes to within 2 cases per cent. of the normal amount of simple hypermetropia-viz., 68 cases per cent. It would almost appear, Mr. Dodd says, as if the increase of astigmatism in epileptics was taken from the normal amount of hyper- metropia. The conclusions at which Mr. Dodd has arrived are that, given a certain condition of instability of the nervous system : (1) errors of refraction may excite epilepsy ; (2) the correction of the errors of refraction will, in combina- tion with other treatment, in many cases cure or relieve the epileptic condition-in the 100 cases forty-nine patients were relieved or cured ; and (3) that in some cases, when the IN the current number of Brain Mr. Work Dodd deals with the question of the relationship between epilepsy and errors of refraction.

The desirability of registration and systematic- sanitary supervision was not denied, but it was held that the, present law could not be construed as giving the necessary , power.

Of the. former class there are still 72 ’95 per cent. on the Register, but the percentage of those holding a diploma now amounts to 26 48. A comparison of the present record with that con-- tained in the Register for 1879, where the respective per-- centages were 90’87 as against 9’13, thus shows a great in- crease in the proportion of qualified dentists to the total number of gentlemen practising that branch of surgery. The- Register also contains the names of twenty-seven dental prac- titioners who hold diplomas granted by the University of Harvard or that of Michigan, but the General Medical Council has decided that these qualifications are not at present registrable. - THE Dentists’ Register for the present year was issued) on the 9th inst. and therefore comes to hand at a much earlier date than in any preceding twelvemonth.

IN the current number of Brain Mr. Work Dodd dealswith the question of the relationship between epilepsy anderrors of refraction. An analysis is given of the results ofexamination of the eyes in 100 cases of true epilepsy, and acomparison is made with the refractions obtaining in appar-ently normal eyes. Of simple hypermetropia there were 28cases per cent. less in the epileptic than in the apparentlynormal class. Of astigmatism of all kinds there were 26 casesper cent. more in the epileptic division than in the normalone, this difference being in great part made up by the in-crease in epileptics of compound hypermetropic astigmatism-viz., eighteen cases more than the normal percentage. Ifthe difference of the 26 cases per cent. of total astigmatismin the epileptic be added to 42 cases per cent. of the simplehypermetropia of the normal class, the result comes to

within 2 cases per cent. of the normal amount of simplehypermetropia-viz., 68 cases per cent. It would almost

appear, Mr. Dodd says, as if the increase of astigmatism inepileptics was taken from the normal amount of hyper-metropia.
