Copper Quotes - page 2
Your Excellency, I am in receipt of His Majesty's royal order, which your excellency communicated to me on the 6th inst., accepting the offer of my work, the 'Caprichos' on eighty copper plate engraved with aqua-fortis by my hand, which I will hand to the Royal Calografia with the lot of prints which I had printed by way of precaution, amounting to two hundred and forty copies of eighty prints, in order not to defraud His Majesty in the least, and for my own satisfaction as to my mode of procedure. I am very grateful for the pension of twelve thousand reals which His Majesty has been pleased to grant to my son [Xavier Goya], for which I offer my best thanks to His Majesty, and to your excellency.... I only desire your excellency's orders, and that you may keep well. May God preserve your excellency's valuable life for many years... Your excellency's obedient and grateful servant, Franco de Goya.
Francisco Goya
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.
