Over a period of a week, the tactics had gone from infantile to novice to advanced, as if someone were learning the intricacies of battle planning.
Infantile mortality is higher, too, in urban tracts, especially those associated with manufacturing industries.

The age is noted for its chronicles, beginning with the anonymous life of the Portuguese Cid, the Holy Constable Nuno Alvares Pereira, told in charming infantile prose, the translated Chronica da fundirao do moesteyro de Sam Vicente, and the Vida Fernao Lopes (q.v.), the father of Portuguese history and author of chronicles of King Pedro, King Ferdinand and King John I., has been called by Southey the best chronicler of any age or nation.
At the same time, where the range is very wide, as between the rates in Scandinavia and Australia, and those in southern and eastern Europe, the variation, to a great extent, cannot be accounted for otherwise than by difference in hygienic conditions, more especially in the light thrown by the figures of infantile mortality in the second part of the table.
