Passing from the plan to the matter of the work, we now ask, whether all that it contains is properly statistical, and whether it contains all of any consequence that falls under that description. Nothing, we suppose, is alien to this branch of knowledge that tends, in however little, to show the state of a country--social, political, moral--or even physical. But this last, comprising somewhat of geography and natural history, some writers would remove entirely from the sphere of statistics. Among these is Peuchet, in his work before mentioned--who gives as the reason of the exclusion, that, in any analysis of the wealth or power of a state, neither its geography nor natural history ever come into view: a fact rather hastily assumed. The parallel work for this country, by Mr. M'Culloch, while it follows Peuchet's method in much, leaves it in this instance, admitting various branches of natural history to ample consideration. It is true that trespass on the proper ground of statistics has been so common an offence, that writers have been careful to mark those cases in which no title exists. Thus Schlozer, looking to the intrusions that come from the quarter we refer to, is averse to all imaginative descriptions of the physical aspect of a country, but does not prohibit natural history. Hogel, who also writes well upon the theory of statistics,[9] is more explicit--admitting that natural history may encroach too far, but asserting that its several branches may be received to a certain extent. "Whatever, in the physical nature of a country, has any influence upon the life, occupations, or manners of the people, pertains to statistics; by all means, therefore, in any body of statistics, let us have as much of mineralogy, hydrology, botany, geology, meteorology, as has any bearing upon the condition of the people." All of these subjects have been allowed to enter largely into the _New Statistical Account_. [9] HOGEL, _Entwurf zur Theorie der Statistik_. They form a feature of that work which scarcely belonged to the old Account, and which is new, indeed, to parochial statistics. Investigations of natural history have usually been carried on with reference to other bounds than those of parishes; but, when confined to parishes, it is remarkable how much this has been at once for the advantage of the science, and for the enhancement of any interest in these territorial divisions by the picturesque mixture of natural objects with the works and pursuits of men. More of this parochial treatment of natural history we may possibly have hereafter, upon the suggestion of the _Statistical Account_.
