In hia able and timely remarks ab the open, ing of the International Congress of Hygiene, ab Sb. "James's Hall, London, Augusb 10th, 1891, the President, the Prince of Wales, said :— ■« The highest pos sible prosperity is when rich and poor alike can do such useful work as the-y are fit for, and to this end it is essential that they should enjoy the best possible health and vigour." Very true, but how oan the pu bI io health be best promoted ? Clearly by such pre ventive measures as the Congress meets to consider, and by reliable remedies so long as certain diseases continue to prevail. We submit an example of tbe latter neces sity in the form of a statement which oan not fail to convince the \ minds of all who may read ib.
