Although the publishing of the ensuing Pamphlet (or Catalogue) may at the first view, seem to several persons a ridiculous and preposterous attempt, yet the Author of this poor Collection humbly hopes, that it will not be exploded or rejected by you, for whose ease and conveniency (together with your forein correspondents) he principally intended it: And if it prove so successful as to receive a favourable acceptance from your hands, the censure of all other persons not concerned in the conveniency arising by it, will not discourage the Author to proceed and make such Improvements of this small Embrio, as may soon bring it to a perfect birth. He humbly hopes no Apology will be required for such Errata’s or Escapes as have been committed as to the Orthography, or true writing of the respective Names of this Catalogue, as well for that he hath found it a very difficult thing, to procure so ample an Account of Names as he hath done; as also in regard his main design is, to publish this forthwith, to the end that if those persons who are concerned in the Use of it, do give it a favourable Receptance, he may set forth an Additional Catalogue far more correct and accurate; wherein if he may receive Encouragement accordingly, he shall not in any thing be better satisfied than that his poor Endeavours shall have answered those Ends for which they were intended.
