A SURVEY of the Principal Subjects of the Illuftrated by Nineteen COPPER-PLATES. By BENJAMIN MARTIN. LONDON, Printed for W. OWEN, N°. 11. near Temple-Bar; and MDCCLXXXII, しか ADVERTISEMENT. O the general account given of this Third Volume in the Preface to Vol. I, the author has only to add, that though the multiplicity of fubjects is very great, and the properties of most of them very fingular and extraordinary, the reader may depend on the truth of the whole; there being scarce an article but what he has had, at times, in his poffeffion, or immediately under his view, and critical examination: particularly those curious fubjects which are reprefented as prefents to EuPHROSYNE'S Museum, he has now by him; and the numerous microscopic views here mentioned, he can repeat to any person, in a cabinet of uncommon variety of objects. In hydrostatics and mechanics, every experiment and inftrument is fo minutely and circumftantially defcribed, that it is prefumed they may be understood without a number of schemes and figures, which are very expenfive, and not near fo fatisfactory as a plain and neat apparatus of inftruments would be, which may be had of the author at a very eafy rate.---To conclude, nothing further occurs to him materially neceflary to initiate Young Ladies and Gentlemen into the mysteries of PHILOSOPHICAL SCIENCE; and he has only to hope, these his laft labours, will be honoured with the fame benign acceptance, as he has heretofore experienced. |
