Professor Lepsius’ goal in this article is to analyze the comments made in the article William Whitney wrote on his “Standard Alphabet” in 1861. After the general characteristics of the “Standard Alphabet” were reviewed and the special modes of representation and selected signs to which William Whitney has expressly given, Professor Lepsius perceives that there remain only a few exceptional cases in regard to which these two scholars have still to come to an understanding. It is of more consequence that Whitney favors the Greek circumflex over the vowel as sign of nasality. The chief obstacle to this method comes from the Tataric languages, in which both vowels are common, and often have to be provided both with the sign of the accent and that of long quantity, which would cause a too great accumulation of signs above the vowel.
