INTRODUCTORY REMARKS BY THE TRANSLATOR.

The Miscellanea Observata, of which a complete translation isnow for the first time submitted to the English reader, waspublished at Leipsic in 1722, in three Parts, to which a FourthPart, published in the same year at Schiffbeck near Hamburgh,was subsequently added. Owing probably to its small size, andseparate publication, the Fourth Part has become exceedinglyscarce, and indeed it is a matter of congratulation that evena single copy could be procured for the completion of the pre-sent work.

The Miscellanea Observata were noticed in the Acta LiterariaSvecice, 1722, and reviewed at greater length in the Acta Eru-ditorum, Lipsiensia for May, 1723, p. 263, and June of the sameyear, p. 96. An able translation of the sexagenary calculus*appeared in the Gentleman’s Magazine for September, 1754;pp. 423, 424, and two of the original papers in the Appendix were translated in the Acta Germanica, London , 1742.

These are the chief periodicals in which the MiscellaneaObservata have been noticed, for we are compelled to pass overthe Historic der Gelehrsamkeit (History of Learning), whichappears also to have reviewed them, as it has shared the samefate as its anonymous composers, and has departed from thememory of men. This review appears to have been actuated

* This new calculus is mentioned at greater length in a letter to the Rev. Dr.Nordberg, which is given in the appendix to his “ History of Charles XII.” Atranslation of the French abridgment of the original letter may be seen in the Intel-lectual Repository, May, 1842, pp. 161—165.
