or, when reading of the DE CLARES, the BOHUNS, or the PERCIES, will see at a glance the connection between “STRONGBOW” and the “red Earl GILBERT,” or will understand the significance of the white swan Badge of the STAFFORDS, or will read at sight the quartered Shield of the Duke of NORTHUMBERLAND, of to-day, and will discern the line that connects the living Earl PERCY with the “HOTSPUR” whose fame was two centuries old when SHAKESPEARE wrote of him? And further, who, that is unable to accomplish such things as these, can appreciate History, can enjoy it and apply its lessons aright? In arranging a Genealogy the utmost conciseness is essential, all details being left for full description elsewhere. All the members of the same family are placed side by side, on the same level, in their order of seniority; and all are connected by lines with one another and with their parents. Successive generations also, throughout all the branches of any family, or in allied families, have their places on the same levels; and the connecting and distinguishing lines are continued throughout. Examples of Genealogies treated in the most scientific and yet simple manner, easy to be understood, and perfect as models for students, may be obtained in any Part of the _Herald and Genealogist_, formerly edited by the late Mr. J. G. NICHOLS, F.S.A., Parliament Street, Westminster. I refer to this excellent Periodical, because it is not possible for me here in the space at my disposal to set forth a really useful example of a Genealogy: and, I must add, because it is most desirable that students of Heraldry should form such an acquaintance with Mr. Nichols, as may be acquired through his works. _Miscellanea Genealogica et Heraldica_, now edited by Mr. W. B. BANNERMAN, is another Periodical, which ought to be in the hands of all Genealogists. In Genealogies, this mark = denotes alliance by marriage, and it is placed between the names of a husband and wife: and the lines that proceed from this mark, thus, = | ________/ \________ / \ point out their issue. The initials S. P. (of the Latin words _Sine Prole_, “without issue”) show where a line or a branch ceases. Other abbreviations and signs in general use will suggest their own signification.
