But very little now remains in our terminology to remind us of the period of Arabian supremacy. The Arabic words naphtha, sumach, alkali, alcohol, elixir and nucha (neck) are almost the only ones which have survived the renaissance. How different the monkish Latin sometimes is from the classic may appear in the use of the two words os and bucca for mouth, or os frontis and glabella for the frontal bone.

But this enumeration must not be prolonged unduly. Let us select three or four more examples almost at random and then pass on. But few will associate Christianity with cretinism. The early Christian inhabitants of the Pyrenees were known as Christaas, or in French, as to-day, as Chretiens. A mountainous region did for them what it has done in Switzerland for the races of to-day, and dwarfed the intellects of many while their thyroids underwent great enlargement. Such degenerates are known everywhere to-day as cretins, i. e., Christians.

Tarentum was the old Calabrian city later known as Tarento, where during the middle ages the dancing mania appeared in aggravated form. The frenzy was known in consequence as tarantism, while the spider whose bite was supposed to cause it was called tarantula, and a rapid dance music which alone would suit such rapid movements is still known as the tarantella.

Nightmare has reference to the old Norse deity or demigod Mara, who was supposed to strangle people during sleep.

The Sardonic grin has reference to a tradition that in Sardinia was found a plant which when eaten caused people to laugh so violently that they died.

But turn we now from words to those deeds which are reputed to proclaim yet more loudly the manner and the worth of their authors. Where may one look for a profession which shall afford greater opportunities? And where may he find one in which incentives are so small? The world's great rewards have been paid to the great destroyers of our race rather than to its saviors. Do you suppose that if Napoleon had saved as many lives as he lost he would have figured in history with his present lustre? It is true that Lister's discovery has saved many more lives than Napoleon took. If so, the Hôtel des Invalides should, when the time comes, contain Lister's monument and not that of a great murderer.

Personal courage is one of the noblest characteristics which any man can display, particularly so when it combines the moral and the physical type. Public bravery brings nearly always its meed of public recognition. In fact, publicity is often the stimulus to a kind of bravery which without it would hardly respond to the tests. But your really courageous man is he who cares not for a search-light to reveal his deeds, one who dares and does within the quietude of his own environment that from which his weaker brothers would shrink.

The soldier stirred to frenzy by the intensity of his passion will accomplish with but little dread that which might easily baffle the resolution of a reasoning man in a calm mood. The religious fanatic, be he Mussulman or Christian, may permit himself to be rent asunder rather than recant; but his motives are essentially selfish, since he looks forward to the Mohammedan's or the Christian's paradise, and so they are far from altruistic. But for that quiet heroism which shuns publicity, which calls for the highest quality of both mental and physical courage, which looks forward neither to the golden present nor the mystical yet sensuous future, commend me daily, yes hourly, to the sick rooms of patients suffering from diseases which menace the welfare of others, the infectious, the dangerous, the loathsome. One may read of late many stories of army surgeons doing heroic deeds under fire, and one's heart naturally thrills with emotion as he imagines the scenes and wonders what manner of daring may lead a man to risk his life after this fashion. But I submit to you, that brave as is such a deed and worthy of all possible honor, it has been hundreds of times for one exceeded in the actual devotion to duty and the resolution required to brave the elements, or to face death elsewhere than on the battlefield, or to surrender strength or mayhap life itself, or to invite disaster by infection, or to wear out and work out life in the constant grinding altruistic work of doing for others, who perhaps have violated every known sanitary law and forfeited their every right to live.

Here is a theme that might well stir the most eloquent poet or orator that ever lived. How then shall I do it justice? Joanna Bailie has well put it:

"The brave man is not he who feels no fear,
