That reminds me to ask, Does your Father prescribe Pepsien in stomach complaints? Has he ever seen the blessed thing? Ever heard of it? If he haven't, no more shame to him, than had he missed to hear of the pretty little French Empress's very latest caprice in dress! This Pepsien (I don't know if I spell it right; but as the word is made out of dyspepsia without the dis, I can't be very wrong) is just the latest caprice in Medicine; that's all!... The Doctors here are prescribing it at no allowance; and the druggists say they can't get enough for the demand.
