“At the latter end of the last century Dr Wood, the present learned and venerable Master of St John's College, Cambridge, in conjunction with the late Professor Vince, undertook the publication of a series of elementary works on analysis, and on the application of mathematics to different branches of natural philosophy, principally with a view to the benefit of students at the Universities. The works of the latter of these two writers have already fallen into very general neglect, in consequence partly of their want of elegance, and partly in consequence of their total unfitness to teach the more modern and improved forms of thosedifferent branches of science. But the works of his colleague in this undertaking have continued to increase in circulation, and are likely to exercise for many years a considerable influence upon our national system of education; for they possess in a very eminent degree the great requisites of simplicity and elegance, both in their composition and in their design. The propositions are clearly stated and demonstrated, and are not incumbered with unnecessary explanations and illustrations. There is no attempt to bring prominently forward the peculiar views and researches of the author, and the different parts of the subjects discussed are made to bear a proper subordination to each other. It is the union of all these qualities which has given to his works, and particularly to his Algebra, so great a degree of popularity, and which has secured, and is likely to continue to secure, their adoption as text books for lectures and instruction, notwithstanding the absence of very profound and philosophical views of the first principles, and their want of adaptation, in many important particulars, to the methods which have been followed by the great continental writers.

“ In later times a great number of elementary works on Algebra, possessing various degrees of merit, have been published. Those, however, which have been written for purposes of instruction only, without any reference to the advancement of new views, either of the principles of the science, or to the extension of its applications, have generally failed in those great and essential requisites of simplicity, and of adequate, but not excessive, illustration, for which the work of Dr Wood is so remarkably distinguished; whilst other works, which have possessed a more ambitious character, have been generally devoted too exclusively to the developement of some peculiar views of their authors, and have consequently not been entitled to be generally adopted as text-books in a system of academical or national education.”Professor Peacock's Report to the British Association On Certain Branches of Analysis.
