_Public records_ appear also to have been examined, and chiefly the parish registers. Every parish has a record of the transactions of its kirk-session,--sometimes extending to distant periods. Extracts from these occasionally show, in a clear light, the state and manners of the country in former times; more of which authentic illustration we could have wished, and more the same sources might possibly have supplied. Most parishes have also records of births or baptisms, marriages and deaths. From these, and these only, this work could derive the elements of its important section of vital statistics; but how far were they fitted to serve that purpose? It is certain that they nowhere form a complete register of these occurrences, and that for the most part they are very defective. Baptisms appear to have been entered, in the parish register, regularly till the year 1783, when the imposition of a small tax first broke the custom of registration; and, when that tax was removed, dissenting bodies were unwilling to resume the practice. The proportion of registered baptisms to births, for instance, is at the present time not more than one fourth in Edinburgh, and one third in Glasgow. The marriage register is also unavailable to statistical purposes, by reason of the practice of double enrolment--in the parish of each party. In many parishes no record of burials exists: in others, those of paupers are omitted. In short, there is scarcely a country in Europe that does not, by proper arrangements, furnish better information on these important points; and no industry of individuals can remedy that defect. It is therefore among the postulates of a work like this, for Scotland, that its vital statistics should be imperfect. _Books_ relating to the history, civil or natural, the institutions or manners of the country, have in many instances been well consulted; in some, not at all; but probably as much from want of opportunity as from any other cause.
