In his late Inspection-Journey to Cleve Country, D'Alembert, from Paris, by appointment waited for the King; [In (_OEuvres de Frederic,_ xxiv. 377-380 (D'Alembert's fine bits of Letters in prospect of Potsdam, "Paris, 7th March-29th April, 1763;" and two small Notes while there, "Sans-Souci, 6th July-15th August, 1763").]--picked up at Geldern (June 11th), as we saw above. D'Alembert got to Potsdam June 22d; stayed till middle of August. He had met the King once before, in 1755; who found him "a BON GARCON," as we then saw. D'Alembert was always, since that time, an agreeable, estimable little man to Friedrich. Age now about forty-six; has lately refused the fine Russian post of "Tutor to the Czarowitsh" (Czarowitsh Paul, poor little Boy of eight or nine, whom we, or Herr Busching for us, saw galloping about, not long since, "in his dressing-gown," under Panin's Tutorage); refuses now, in a delicate gradual manner, the fine Prussian post of Perpetual President, or Successor to Maupertuis;--definitely preferring his frugal pensions at Paris, and garret all his own there. Continues, especially after this two months' visit of 1763, one of the King's chief correspondents for the next twenty years. ["29th October, 1783," D'Alembert died: "born 16th November, 1717;"--a Foundling, as is well known; "Mother a Sister of Cardinal Tencin's; Father," accidental, "an Officer in the Artillery."] A man of much clear intellect; a thought SHRIEKY in his ways sometimes; but always prudent, rational, polite, and loyally recognizing Friedrich as a precious article in this world. Here is a word of D'Alembert's to Madame du Deffand, at Paris, some ten or twelve days after the Cleve meeting, and the third day after his arrival here:-- "POTSDAM, 25th JUNE, 1763. MADAME,--... I will not go into the praises of this Prince," King Friedrich, my now Host; "in my mouth it might be suspicious: I will merely send you two traits of him, which will indicate his way of thinking and feeling. When I spoke to him [at Geldern, probably, on our first meeting] of the glory he had acquired, he answered, with the greatest simplicity, That there was a furious discount to be deducted from said glory; that chance came in for almost the whole of it; and that he would far rather have done Ratine's ATHALIE than all this War:--ATHALIE is the work he likes, and rereads oftenest; I believe you won't disapprove his taste there. The other trait I have to give you is, That on the day [15th February last] of concluding this Peace, which is so glorious to him, some one saying, 'It is the finest day of your Majesty's life:' 'The finest day of life,' answered he, 'is the day on which one quits it.'...--Adieu, Madame."
