With respect to the quotations or synonyms, it should be observed that we have in most instances limited them only to original works, all doubtful ones have been rejected, and such only given as have been actually consulted; indeed to this latter cause must be attributed the occasional omission of some, existing in books we had not the immediate power of consulting; our own library is not small; but the difficulty and expense of procuring all the new continental publications, and the impossibility of meeting with them at our public libraries[[2]], may have sometimes led us into error, and unintentionally to have passed over the discoveries of others.

With the few additions contained in the Appendix we shall now conclude; trusting that in the remarks drawn from us by the present state of the science in this country, our zeal for truth will not give us an appearance of want of candour or of vanity. The truth of our remarks on the labours of others, every one at all acquainted with the subject can inquire into, and either acknowledge or disprove: we neither deprecate nor despise criticism: an author who presumes to instruct others, should have his pretensions publicly canvassed, his merits admitted, or his deficiency exposed; no one is more sensible than we are that our own pretensions chiefly consist in having set an example for others more able to follow: and if we have in any way advocated the cause of truth and science, our object will be attained, and we shall then gladly retire in the shade.
