P. K. RAY'S DEDUCTIVE LOGIC. 587 always the risk (as on p. 408) of a boomerang- like theologic counter-stroke, telling back against the very philosophy of science which he professes and, it may well be believed, sincerely seeks to aid and advance. Suffering from this misadventurous Parthian shot out of his final page, one may turn for healing and comfort to the thought, that Experience on a vast and secular scale moves on like a sea, soaking, sapping, sinking, founding. Of no avail are pious zeal, infinite labour, erudition, bright and clear style, copious and apposite illustration, shapely and plastic method, subtle patience in distinguishing, defining and dovetailing, like Father Harper's, if his works and days do not tell for the things and causes that are saved by living and moving onward and upward with the great tide. And, with the " confidence " of the " gnostics " he derides (p. 205), or rather of those called agnostics, who do r/nt know and know they do not, yet believe and hope, one may dare to foretell of these books, however worthily conceived and well- meant, and of such as these, that they will only remain as a curious kind of submerged museum or necropolis ; or, put more aptly, as a sunken reef of rocks that are now worn bare and never not even in their own age supplied the true nourishment and proper soil of the saintly, noble and human lives that nourished then as now, and that will, we hope, more and more abundantly flourish, bearing more perfect fruit, when " the Meta- physics of the School" is summed up in an epigram and laid aside, or is shut up and shelved like an antediluvian fly in amber, if, indeed, it is not washed clean out of the remembrance of man, and left behind and below in his upbuilding, a hidden sediment and residuum, effete, dead, and buried without hope of resurrection.

Calcutta : Thacker, Spink ; London : Thacker, 1884. Pp. xv., 335. This work is doubtless primarily intended to meet a demand for logical training in Dr. Kay's own country ; and it speaks well for logical study in India that it should have called forth a text- book of such a high degree of merit as the one before us un- doubtedly possesses. The author commences by calling attention to the three opposed views of Logic, of which in England, Mansel, Mill, and Whately may be regarded as the most distinctive representatives ; but, as he holds that they all contain elements of truth, he does not confine himself to any one of them to the exclusion of the two others. Now it will be generally agreed that a reconciliation of divergent doctrines, if it can in any way be effected, is especially
