There is a mode of printing used in Cuvier's _Règne Animal_, which is exceedingly useful for books of classification, that is, to print those sentences which relate to the primary divisions in a larger type, and full up to the side; the subdivisions to be printed short, as sums are entered in an account book, and in a smaller type. I believe I had the fortune to introduce a slight improvement in indexes. For instance, in your index the subordinate items are arranged according to time, but that gives a great deal of trouble. Under MR. BREEN'S name there are fifteen items; they should be arranged alphabetically, like the principal items, as is done in the same index in the case of notices of books, unavoidably. But such subordinate items had better, in general, have the word on which the alphabetical arrangement turns printed in Italics to catch the eye, rather than invert the order of the words, as _must_ be done in the principal items. In what books the old spelling should be retained is a matter of individual question, upon which no rules can be laid down. Walpole complained that the _Paston Letters_ were printed with the old spelling, and that, though a version is on the opposite page; but few persons will agree with him in that. In such books we have a right to see the old spelling in order to judge whether the version is right, as well as for general information. C. B. _The Ring-finger_ (Vol. iv., pp. 150. 198. 261.).--The two questions mooted concerning the ring-finger, _i.e._ why the third finger is the ring-finger, and why the wedding-ring is worn on the third finger of the left hand? have not yet been satisfactorily answered. The _third finger is the only recognised ring-finger_. Hence all who wear rings _ex officio_, wear them on that finger. Cardinals, bishops, doctors, abbots, &c., wear their ring on the third finger. The _reason is that it is the first vacant finger_. The thumb and the first two fingers have always been reserved as symbols of the three persons of the Blessed Trinity. When a bishop gives his blessing, he blesses with the thumb and first two fingers. Our brasses and sepulchral slabs bear witness to this fact. And at the marriage ceremony, the ring is put on to the thumb and the first two fingers, whilst the names of "The Father, and the Son, and the Holy Ghost" are pronounced. Thus the third is the first vacant finger, and the ring-finger. _The wedding-ring is worn on the left hand to signify the subjection of the wife to her husband._ The right hand signifies power, independence, authority; according to the words: "The salvation of his right hand is in powers." Psalm xx. 6. "The change of the right hand of the Most High." Psalm lxxvii. 10. The left hand signifies dependence or subjection. Married women, then, wear the wedding-ring on the third finger of the left hand, because they are subject to their husbands.
