Among material changes introduced into this edition may be mentioned the abolition of the term Sewd medium 10 d). In this I have adopted, not without hesitation, the views of Sievers. I find it, however, quite impossible to follow him in rejecting all distinctions OT quantity in the vowels. It is no doubt possible that such matters may in the spoken language have worn a very different appearance, and especially that in the period of nearly a thousand years, over which the Old Testament writings extend, very great variations may have taken place. Our duty, however, is to represent the language in the form in which it has been handed down to us by the Masoretes; and that this form involves a dis tinction between unchangeable, tone-long, and short vowels, admits in my Opinion of no doubt. The discussion of any earlier stage of development belongs not to Hebrew grammar but to comparative Semitic philology.
