LIS. Let me ask you, at this stage of our inquiries, what you mean by bibliographical publications?--and whether the works of those authors which you have enumerated are sufficient to enable a novice, like myself, to have pretty accurate notions about the rarity and intrinsic value of certain works? LYSAND. By bibliographical publications, I mean such works as give us some knowledge of the literary productions, as well as of the life, of certain learned men; which state the various and the best editions of their lucubrations; and which stimulate us to get possession of these editions. Every biographical narrative which is enriched with the mention of curious and rare editions of certain works is, to a great extent, a bibliographical publication. Those works which treat professedly upon books are, of course, immediately within the pale of bibliography. LIS. But am I to be satisfied with the possession of those works already recommended? PHIL. I suppose Lisardo has heard of certain valuable CATALOGUES, and he wishes to know how far the possession of these may be requisite in order to make him a bibliographer? LYSAND. At present I will say nothing about the catalogues of the collections of our own countrymen. As we have been travelling principally abroad, we may direct our attention to those which relate to foreign collections. And first, let us pay a due tribute of praise to the published Catalogues of Libraries collected by the JESUITS: men of shrewd talents and unabating research, and in derogation of whose merits Voltaire and D'Alembert disgraced themselves by scribbling the most contemptible lampoons. The downfall of this society led, not very indirectly, to the destruction of the ancient French monarchy. Men seemed to forget that while the most shameless depredations were committed within the libraries of the Jesuits, the cause of learning, as well as of liberty, suffered,--and the spoils which have glittered before our eyes, as the precious relics of these collections, serve to afford a melancholy proof how little those men stick at any thing who, in raising the war-whoop of liberty and equality, tear open the very bowels of order, tranquillity, peace, and decorum! But, to the subject. Let the catalogues of PUBLIC COLLECTIONS, when they are well arranged, be received into your library. Of foreign PRIVATE COLLECTIONS, the catalogues[162] of DU FRESNE, CORDES, HEINSIAS, BALUZE, COLBERT, ROTHELIN, DE BOZE, PREFOND, POMPADOUR, GAIGNAT, GOUTTARD, BUNAU, SOUBISE, LA VALLIERE, CREVENNA, LAMOIGNON, and of several other collections, with which my memory does not just now serve me, will enable you to form a pretty correct estimate of the _marketable value_ of certain rare and sumptuous publications. Catalogues are, to bibliographers, what _Reports_ are to lawyers: not to be read through from beginning to end--but to be consulted on doubtful points, and in litigated cases. Nor must you, after all,
