done little towards annihilating poverty; and we fear that Peniten-

Moral maladies require moral remedies. So extensive and pervading
an evil is not to be cured by private exertion, and by the very

an unsanctioned intercourse between the sexes, prevail to any extent,
it is fair to look for the cause to difficulties thrown in the

way

of
marriage, either by improvident laws, or by the unavoidable expences
of life; to the existence of a wrong mode of education; to the want
of affording the sex proper protection; and to the cherishing of cer.
tain rigid principles, which prevent the return to virtue. Men in so.

principles, and of the habits and circumstances which these generate.
A multitude of common prostitutes indicates a defect in the practical
code of ethics; it shews that there are certain principles of conduct
tolerated, which, though they may not sanction vice, do at least take
from the idea of its deformity ;-it indicates also, that the natural in-
clination of the sexes towards each other is not so properly contema
plated by the law as it ought to be ; and moreover, that the progress
of refinement and luxury has in some cases prevented the possibility of,
and in others the inclination to, an union for life. ri

SERMONS.
Art. 73. On the Excellence of British Jurisprudence, preached

10th March 1799, in the Cathedral Church of Salisbury, before
the Judges of Assize. By William Coxe, A.M. F.R.S. F.A.S.
Rector of Bemerton. 8vo. 15. , Cadell jun. and Davies.

This sermon is admirably suited to the occasion on which it was de
livered. Mr. Coxe compresses into a narrow compass an account of
the British Legislature, and particularly that part of it which re-
spects criminal jurisprudence. To this object it is impossible to di-
rect our view without the highest satisfaction. Our criminal courts,
indeed, exhibit a beautiful feature of the British Constitution. If it
be not perfect, there is none on earth more so. Mr. C. justly ob-
serves, - This Constitution unites the wisdom of the most complicated,
with the facility of most simple forms, and is, as nearly as the works
of frail and feeble nan can approach perfection, perfect in all its
parts. All classes of society are blended without confusion, and yet
distinguished without opposition or separation. There is no person
so exalted, who can offend with impunity, there is no person so
humble, to whom in favour of industry, perseverance, or genius, the
road to honour and wealth is not open. This Constitution is so well
adapted to all conditions of life, that every man is at once the guar-
dian, the censor, and the surety of his neighbour.'

The profits of the sale of this sermon, we are told, will be appropriated to the use of the Salisbury Infirmary.

Art. 74: A Defence of Itinerant and Field Preaching : preached bew

fore the Society for Gratis Sabbath-schools, 24th December, 1797 in Lady Glenorchy's Chapel, Edinburgh. By Grenville Ewing, Minister of the Gospel. 8vo. pp. 58. 18. Ogle. 1799.

The beautiful imagery of this writer's text (Prov. i. 21, 22.) is Illustrated and exemplified daily, and its truth is continually established. Wisdom, indeed, orieth without, she uttereth bor voice in the streets, &c. Yet we can scarcely suppose that this preacher, a man of sense as he undoubtedly is, would explain metaphorical language, brighly but justly wrought, in a literal manner; and hence extract an wgument in support of the practice mentiened above. However, he proceeds to furnish a long list of street-preachers, &c. from the dayɛ of Enoch the seventh from Adam, to the time of our Saviour, and his apostles, with their contemporaries and successors, who were employed to disseminate the principles of Christian truth in a dark and ignorant world. When our field-preachers produce their credentials, and prove beyond a doubt, by miracles and similar testimonies, that they are divinely commissioned and inspired, we shall be constrained to allow them due attention: otherwise, we should apprehend that, in a country in which Christianity is known and professod, if the numerous body, to whose office it more directly belongs, applied themselves with assiduity to recommend and enforce its practical truths, the great and important ends of religion and virtue might be attained with out much of this interference. Far be it from us to condemn, however, or rashły to ensure, well-meant exertions to do good to mankind. Whether the dass of men, whose cause is here pleaded, do generally and really understand Christianity; whether they do not talk much nonsense; or whether at least a great part of them do not preach Your Calvin rather than Jesus Christ ;-these are questions, on a discussion of which we will not enter.

The reader will find in this discourse several judicious observations, and useful thoughts; and the author discovers some enorgy of language and of argument. The tonfettered preaching of the gospel is an object for which he contends -he discards a mere political religion, though mve do not perceive that he objects to the trammels of creeds and conEessions.

circumstances which are accidental, or of little moment, rather than by any decision of the judgment after a careful examination of the advantages and disadvantages which each object of inquiry presents, yet are they eager and zealous in extolling their own pursuits and depreciating those of other people. Hence terms of contempt have been interchanged between the respective advocates for law, poetry, science, natural philosophy, &c. with little reason and less temper. That some pursuits are preferable to others is true, because there are some which are evidently frivolous, or followed beyond any object of rational attainment - but, were the aim and tendency of every research in science and literature what they ought to be,- either mental instruction or mentai delight,-it would be difficult to say why one research was preferable to another ; or to state arguments for the neglect of any study, which would not operate to its complete exclusion.

OF

Of the many and various arguments, however, to which pride and the fertility of invention have given birth, none seems to have gained a more general reception, than those which have been urged against pure and abstract science. The mathematics have been represented as most unfit for purposes of wealth, of enjoyment, or of ambition; as punishing students with languor and moroseness ; rendering them indifferent, even as the gods of Epicurus, to all objects of human concern ; 'exempting them from the influence of passion; and consequently suffering them to partake of a small portion only of the good and evil of life. The disciples of Euclid and Newton are not only not to be moved by trivial accidents and petty vexations, but are insensible even as Archimedes while the sword of death was descending on him.

These arguments, which are plausible because they are in part just, have been deemed incontrovertible by some who have not sufficiently considered the nature of the human mind, of abstract science, and of the true object of life; in general, too, they have been

urged by men who have not been distinguished by variety, by extent, nor by accuracy of knowlege ; by men who have neither added to truth, nor embellished it *.. The defence of the mathematics has been rare, because the culti. vators of this science have not been very ambitious of gaining the public suffrage in favour of its propriety and advantages : but the defence las been made : it has been urged that the mind has its wants, as well as the body; that the food of the mind is truth,--and that truth, genuine and sure, is to be found in the mathematics ;, that it is desirable to reason justly, although on frivolous subjects; and that the science, therefore, is worthy of regard, which gives to the mind a habitude of just argumentation, and renders it pliant to truth. On reasons like these, has the vindication of what may be called the spiritual and philosophical utility of the mathematics been conducted. Its gross and material utility furnishes a not less sure and ample ground of defence ; and this ground is to be sought amid the variety of inventions which add to the comforts and luxuries of so

and amid those arts by means of which commerce is conducted with safety and expedition t. In this subserviency of spe

culative : * Fontenelle says that “mer, indulging a species of revenge, abuse what they do not understand, or what is hard to be underscood ; and the mathematics are difficult of access, thorny and ardnous."

# The following passage, from the celebrated preface to the Memoirs of the Academy of Sciences, illustrates and enforces what we have said :

culative truth to abstract good, in this investment of abstract con-
ceptions with power, consists what Bacon calls,“the deep, fruitful,
and operative study of the sciences ;” and indeed the advantages
to be derived from the co-operation of scientific and mechanical
ingenuity are too evident, and 100 demonstrable, to be denied.
On this account, the impugners of the mathematics have
thought to deprive them of their fairest title and most weighty
recommendation, by asserting that improvements in the mea
chanical arts rarely originate from merely speculative philoso-
phers, but are due to the genius of mechanics who are unread
and unlearned in the subtile, connected, and refined reasonings
of an Euclid, a Newton, or an Euler. This assertion is
indeed partly true: it is in a great measure warranted by expe-
rience, and may be made probable by an examination of the
mental habits and modes of reasoning induced by the study of
pure and abstract science.

Considering the truth of the assertion as established à poste-
riori, it may be observed that, although the examples of a
Newton and a Galileo might be adduced, and of an Archi-
medes who rose from his figures to animate and direct powers
which scattered dismay and ruin over the arms of the most
warlike nation on earth, yet the great benefactors of the arts
have been men who were not trained in all the discipline of

“ We have a moon to enlighten us during our nights : of what concernment to us is it that Jupiter should have four ? Why so many tedious observations, so many fatiguing calculations, to obtain an exact knowlege of their courses? We shall not be more enlightened ; and

nature, which has placed these small stars beyond the view of
our eyes, seems not to have intended them for us. Influenced by
reasoning so plausible as this, we ought to shun the observation of
satellites with a telescope, and the investigation of their motions :
-yet it is certain that we should thus be

great losers.
* Whoever is even slightly acquainted with the principles of riavi.
gation, and of geography, knows that, since the discovery of the
four moons of Jupiter, science has been more benefited by them than
by our own: that these moons serve, and will continue to serve, with
increasing utility, to make marine charts beyond all comparison
more exact than they were in autient times ; and consequently to
preserve the lives of an infinite number of mariners. Did astronomy
derive no other benefit than this from the satellites of Jupiter, it
would be sufficient to justify those immense calculations, those ob-
"servations so assiduously and so scrupulously made, this grand appa-
ratus of instruments, this superb building, devoted to the sole use
of the scienee! In the mean time, the mass of mankind have no
knowlege of the satellites of Jupiter, or such as is confused, and

scraped up from common report ;-or they are ignorant of the con-
· section of these moons with navigation -- or even that in late times
gavigation has been rendered more perfect,"
