And now, my dear friend, you must make your bow with me to M. Hebert, and bid farewell to the PUBLIC LIBRARY at Caen.  Indeed I am fully disposed to bid farewell to every thing else in the same town:  not however without being conscious that very much, both of what I have, and of what I have not, seen, merits a detail well calculated to please the intellectual appetites of travellers.  What I have seen, has been indeed but summarily, and even superficially, described; but I have done my best; and was fearful of exciting ennui by a more parish-register-like description.  For the service performed in places of public worship, I can add nothing to my Rouen details—­except that there is here an agreeable PROTESTANT CHURCH, of which M. MARTIN ROLLIN, is the Pastor.  He has just published a “Memoire Historique sur l’Etat Eclesiastique des Protestans Francois depuis Francois Ler jusqu’a Louis XVIII:”  in a pamphlet of some fourscore pages.  The task was equally delicate and difficult of execution; but having read it, I am free to confess that M. Rollin has done his work very neatly and very cleverly.  I went in company with Mrs. and Miss I——­ to hear the author preach; for he is a young man (about thirty) who draws his congregation as much from his talents as a preacher, as from his moral worth as an individual.  It was on the occasion of several young ladies and gentlemen taking the sacrament for the first time.  The church is strictly, I believe, according to the Geneva persuasion; but there was something so comfortable, and to me so cheering, in the avowed doctrine of Protestantism, that I accompanied my friends with alacrity to the spot.  Many English were present; for M. Rollin is deservedly a favourite with our countrymen.  The church, however, was scarcely half filled.  The interior is the most awkwardly adapted imaginable to the purposes either of reading or of preaching:  for it consists of two aisles at right angles with each other.  The desk and pulpit are fixed in the receding angle of their junction; so that the voice flies forth to the right and left immediately as it escapes the preacher.  After a very long, and a very tediously sung psalm, M. Rollin commenced his discourse.  He is an extemporaneous preacher.  His voice is sweet and clear, rather than sonorous and impressive; and he is perhaps, occasionally, too metaphorical in his composition.  For the first time I heard the words “Oh Dieu!” pronounced with great effect:  but the sermon was made up of better things than mere exclamations.  M. Rollin was frequently ingenious; logical, and convincing; and his address to the young communicants, towards the close of his discourse, was impressive and efficient.  The young people were deeply touched by his powerful appeal, and I believe each countenance was suffused with tears.  He guarded them against the dangers and temptations of that world upon which they were about to enter, by setting before them the consolations of the religion which they had professed, in a manner which indicated that he had really their interests and happiness at heart.
