IN the two years that haye followed the translation of the First Volume of the Grundriss der vergleichenden Sprachwissenschaft by Dr. (now Professor) Joseph Wright, the difficulty of the task has sensibly diminished. The methods and the nomenclature of the scientific school of Comparative Philology have found their way more and more into the work of English teachers, and it has become far easier to decide what innovations can, and what cannot be reconciled with established usage. Such words, for example, as 'thematic', 'ablaut', 'analogical', 'contamination, 'proethnic' are completely naturalised.

'Philology , i. e. of that science, which has to investigate the intellectual development of the Indg. peoples from the time before their separation up to the present day. Its method accordingly is historical and its task is to investigate the whole development of the Indg. languages from the time when they were still one language down to the present day. Its unity is in no sense broken by the results furnished by the specialists in Sanskrit, Ancient and Modern Greek, Latin and the Romance languages, Keltic etc., for the sciences of the Indian languages, of Ancient and Mod. Greek etc. are integral components of the grand whole formed by that of the Indo-Germanic.

It is true that the so called comparative science of language has hitherto been almost exclusively confined to the older periods of the Indg. languages, but this is due to the division of labour which was involved in the method by which alone progress could be made, as well as to the limitations of human strength. Probably the same division of labour will still be necessary, but it implies no real opposition between the different parts of the science….
