view. The source of the difficulty seems to be in the definition of the word power. Davies says, following the universal custom we believe,-" The power of a quantity is the product which results from multiplying the quantity by itself," and an exponent, though not expressly defined to be such, is still represented to be the number that shows how many times the number is taken as a factor. This is applicable to all those powers whose indices are positive and plural, but we want a representation of the case which will include the whole class, for they all are evidently one in nature; such as
ja, a, a-2, al, a-, Only one of the above is the product of a quantity multiplied by itself, and of course only one is included under the definition. Now there certainly is a very clear and obvious analogy between these expressions, i. e. clear and obvious in its nature, however difficult it may be to clothe it in language. It links them together, forms of them one class, and enables us to combine the indices and operate upon them in every way, as numbers identical in their nature. This hidden analogy we ought to develop, and make it the foundation of the theory instead of giving a definition, as we always do now, which applies only to one of the above cases, and then empirically extends our reasonings and rules to the others.
In fact there is a confusion exactly analogous to this, farther back, in the ordinary attempts at defining multiplication. The true general idea of multiplication is not expressed, or even attempted to be expressed. Bailey says, as in fact most writers on arithmetic and algebra substantially do, “ Multiplication is merely a short way of performing addition, when the quantities to be added happen to be equal.” Peirce, Davies and Euler, as if instinctively shrinking from the difficulty, attempt no definition whatever. In respect, however, to the common definition, we may ask what addition is it that is performed in the case a x1, or a x 1, or a x-1? To this question it may perhaps be replied that the term multiplication is in strict propriety applied only to the case where the multiplier is positive and plural; and this may be a sufficient answer, though far from satisfactory to us. In all the above cases the operations are strictly analogous, the term multiply is constantly used by all writers in respect to each of them, and we cannot but think that the perfection of science requires that this common analogy should be made the foundation of the definition and the theory. It ought however to be stated, distinctly that the authors of these works are not in fault at all, in respect to these points. It is the present state of the science that we are criticising, and not the success of their attempts to exhibit it. In respect however to the theory of powers and the analogy of positive, negative, integral and fractional exponents, we had some further suggestions to make, but must postpone them to some future occasion.
Art. III.-ACADEMIES IN NEW ENGLAND.
ANOTHER defect in the constitution of the Academies of New England is the want of funds. From this want arises that dependence on popular favor, which, if it require these institutions to keep pace with the improvement, real or fanciful, of the age, also and for that very reason, forbids the establishment and enforcement of any thorough plan of discipline, or any permanent system of instruction. The resources of these institutions are in most instances too meagre to support an adequately qualified teacher, and those who are not willing to be subject to the caprice of patronage, seek a surer competence in a steadier occupation. The same difficulty substantially is felt in nearly every school and college in the country. In many of the latter the Professors are straitened for the means of subsistence. The consequence is obvious. The dependent cannot well be manly, and in a cause which most of all ought to be kept aloof from the changing influences of party and of whim, the seeking of favor introduces servility, and the clamors of the ignorant are more regarded than the decisions of the learned. We have ample proof of the utility of permanent endowments in the instance of the few academies among us which are thus provided. Were it not in vidious we could select instances thoroughly in point.
We have said that academies are like to be continued in New England for many years. Many of the larger towns in Massachusetts and probably in other States, have recently
established High Schools, which will draw off many students who have been accustomed to resort to academies. This, however, will effect no material change in the system of instruction hitherto practised, and certainly will not, we think, diminish the number of academies. If this scheme of instruction, which has been a favorite one in New England, is to be continued, the establishment of it on a foundation of stable utility is a duty which the friends of it will hardly attempt to evade.
We have no full statistical account of the incorporated academies in New England. The following statement will be found, we think, not far from accurate. In Maine are 40, more than half of which are endowed with 11,500 acres of land. In New Hampshire, about 40, several of which have large funds. In Vermont, between 20 and 30, slightly or not at all endowed. In Massachusetts, about 60, 23 of which have received from the State a tract of land in Maine, six miles square. In Connecticut, about 30. C. C.
We annex to the foregoing article, a list of academies in New Hampshire and Massachusetts, taken from the American Quarterly Register, and amended according to our best knowledge. The list was made several years ago and some changes may have been made of which we are not aware.
