COLLINS PRINTERS. 771 D55 1852 PREFACE. IN the following pages, the attempt has been made. to engage the attention of the intelligent reader in the discussion of subjects usually, though erroneously, regarded as of technical rather than of universal interest. This exclusive character has become attached to them more from the manner in which they have been presented, than from anything in their own nature; and they are here brought forward in a point of view which, if somewhat novel, will, it is hoped, be found as generally acceptable as it is rational and obvious.
