Epilepsy Or Fits A sure cure for this distressing complaint is now made known in a Treatise of 48 octavo pages, on Foreign and Native Herbal Preparations, published by Dr. O. Phelps Brown. The prescription was discovered by him in such a providential manner that he cannot conscientiously refuse to make it known, as it has cured everybody who has used it for Fits, never having failed in a single case. The ingredients may be obtained from any druggist. Persons desiring a copy may address Dr. O. Phelps Brown, No. 21 Grand Street, Jersey City, N. J., and it will be sent by return mail.

The Reasons Why

D

OOLEY'S YEAST POWDER is preferred to any other Baking Powder in market, are owing to its perfect purity, quality, quantity, and economy. The ingredients are strictly free from deleterious substances, and hence the full strength of each is obtained, and the results are uniform every time it is used. This cannot be the case in those of ordinary manufacture, and for proof of our assertion, we ask those who have never used Dooley's Yeast Powder to give it a trial. Your grocer keeps it.
