Now that lay journals are aiding in the exposure of the evils of the nostrum traffic, there is increasing lay interest and discussion of medical affairs. Thus we find reference to druggists paying commissions to physicians on prescriptions, and of course the practice properly is condemned. It is indefensible, and we hope it is not sufficiently common to need more than passing remark. As the public becomes better posted on these points, the offender in this respect must not be surprised when he meets with exposure and loss of professional standing. Such methods are certain of ultimate discovery, and it is folly to risk one's reputation for so petty and so mercenary a stake.
