THEORY OF STATISTICS. 
(5) GABAGLIO, ANTONIO, Teoria generale della statistica, 2 vols.; Hoepli, 
Milano, 2nd edn., 1888. (Vol. i, Parte storica.) 
Several works on theory of statistics include short histories, e.g. 
H. Westergaard’s Die Grundziige der Theorie der Statistik (Fischer, 
Jena, 1890), and P. A. Meitzen’s Geschichte, Theorie und Technik der 
Statistik (new edn., 1903 ; American translation by R. P. Falkner, 
1891). There is no detailed history in English, but the article 
‘“ Statistics” in the Encyclopeedio Britannica (11th edn.) gives a very 
slight sketch, and the biographical articles in Palgrave’s Dictionary of 
Political Economy are useful. For its importance as regards the English 
school of political arithmetic, reference may also be made to—

with the Observations on the Bills of Mortality more probably by Captain 
John Qraunt, Cambridge University Press, 2 vols., 1899. 
History of Theory of Statistics. 
Somewhat slight information is given in the general works cited. 
From the purely mathematical side the following is important: —

from the time of Pascal to that of Laplace ; Macmillan, 1865. 
History of Official Statistics.

scientifiques, 1895. (Gives an exceedingly useful outline of the history 
of official statistics in different countries.)
