1. dnvention of Stereotyping.—The honor of this important in- 
vention is at present claimed by Holland, and apparently with justice. 
Baron Van Westreemen Van Tiellandt, encouraged by. the. govern- 
ment, has made very active researches on this subject, and has late- 
ly received from the bookseller Luchtmans, of Leyden, a stereotype 
form of a Bible, in 4to, from which many impressions have been ta= 
ken since 1711. At Harlem, also the booksellers Enschedé, have 
furnished him with another stereotype form of a Dutch Bible, which 
dates from the first years of the eighteenth century. ‘These are two 
substantial proofs of stereotyping in Holland, before it was thought of 
in France. It is well known, that in a note annexed to No. 1316, 
of the Catalogue of Alex. Barbier, a note extracted from the papers 
of Prosper Marchand, it is affirmed that John Muller, minister of 
the German church at Leyden, contrived about 1701, anew method 
of printing, similar to stereotyping as. now practised. The method 
of John Muller, consisted in composing the letters in the common 
Way, correcting these forms very exactly, binding them in a very solid 
manner in frames of iron, then inverting the letters, and uniting the 
with metal, or still better with mastic. ‘The first essay of this meth- 
od, was a small prayer book entitled, Gebeede-Boolyen, Van Johan 
Haverman, printed in 1701, by W. Muller, son of the inventor. This 
method of printing was afterwards transported to Halle. In a letter, 
of the 28th of June, 1709, Muller acknowledges that he had printed 
in this manner, a Syriac New Testament with a Lexicon. Camus

was presented to the Academy of Sciences at Paris, on the a. 5th of 
December, by M. Ampere, on a newly constructed hy drostatic lamp, 
which concludes as follows:—The modifications of the lamps sub-

emanations. M. M. Thilorier and Barrachin, by making the beak
