„Chemical signs ought to be letters, for the greater facility of writing, and not to disfigure a printed book... I shall take therefore for the chemical sign, the initial letter of the Latin name of each elementary substance: but as several have the same initial letter, I shall distinguish them in the following manner:— 1. In the class which I shall call metalloids, I shall employ the initial letter only, even when this letter is common to the metalloid and to some metal. 2. In the class of metals, I shall distinguish those that have the same initials with another metal, or a metalloid, by writing the first two letters of the word. 3. If the first two letters be common to two metals, I shall, in that case, add to the initial letter the first consonant which they have not in common: for example, S = sulphur, Si = silicium, St = stibium (antimony), Sn = stannum (tin), C = carbonicum, Co = colbaltum (colbalt), Cu = cuprum (copper), O = oxygen, Os = osmium, &c.“

„There'll be a day when I shall begin something that I shan't finish — a walk, or a letter, or a sentence, or a dream.“

— Henri Barbusse French novelist 1873 - 1935
Context: When you look straight on, you end by seeing the immense event — death. There is only one thing which really gives the meaning of our whole life, and that is our death. In that terrible light may they judge their hearts who will one day die. Well I know that Marie's death would be the same thing in my heart as my own, and it seems to me also that only within her of all the world does my own likeness wholly live. We are not afraid of the too great sincerity which goes the length of these things; and we talk about them, beside the bed which awaits the inevitable hour when we shall not awake in it again. We say: — "There'll be a day when I shall begin something that I shan't finish — a walk, or a letter, or a sentence, or a dream.".

„It is the initial letters of the four points of the compass that make the word "news," and he must understand that news is that which collies from the North, East, West and South, and if it comes from only one point of the compass, then it is a class publication, and not news.“
