Friedrich's dismissal of Selle, June 4th, by no means meant that he had given up hope from medicine; on the contrary, two days after, he had a Letter on the road for Zimmermann at Hanover; whom he always remembers favorably since that DIALOGUE we read fifteen years ago. His first Note to Zimmermann is of June 6th, "Would you consent to come for a fortnight, and try upon me?" Zimmermann's overjoyed Answer, "Yes, thrice surely yes," is of June 10th; Friedrich's second is of June 16th, "Come, then!" And Zimmermann came accordingly,--as is still too well known. Arrived 23d June; stayed till 10th July; had Thirty-three Interviews or DIALOGUES with him; one visit the last day; two, morning and evening, every preceding day;--and published a Book about them, which made immense noise in the world, and is still read, with little profit or none, by inquirers into Friedrich. [Ritter von Zimmermann, _Uber Friedrich den Grossen und meine Unterredungen mit Ihm kurz von seinem Tode_ (1 vol. 8vo: Leipzig, 1788);--followed by _Fragmente uber Friedrich den Grossen_ (3 vols. 12mo: Leipzig, 1790); and by &c. &c.] Thirty-three Dialogues, throwing no new light on Friedrich, none of them equal in interest to the old specimen known to us. In fact, the Book turns rather on Zimmermann himself than on his Royal Patient; and might be entitled, as it was by a Satirist, DIALOGUES OF ZIMMERMANN I. AND FRIEDRICH II. An unwise Book; abounding in exaggeration; breaking out continually into extraneous sallies and extravagancies,--the source of which is too plainly an immense conceit of oneself. Zimmermann is fifteen years older since we last saw him; a man now verging towards sixty; but has not grown wiser in proportion. In Hanover, though miraculously healed of that LEIBESSCHADE, and full of high hopes, he has had his new tribulations, new compensations,--both of an agitating character. "There arose," he says, in reference to some medical Review-article he wrote, "a WEIBER-EPIDEMIK, a universal shrieking combination of all the Women against me:"--a frightful accident while it lasted! Then his little Daughter died on his hands; his Son had disorders, nervous imbecilities,--did not die, but did worse; went into hopeless idiotcy, and so lived for many years. Zimmermann, being dreadfully miserable, hypochondriac, what not, "his friends," he himself passive, it would seem, "managed to get a young Wife for him;" thirty years younger than he,--whose performances, however, in this difficult post, are praised.
