42 INTRODUCTION. 
Villa Nova has only three hundred and sixty-three 
lines, Moreau mentions, that a manuscript belonging 
to Naudius had only one hundred and eighty-three, 
his own had six hundred and sixty-four, that of 
Trews one thousand and seventy three, Tullous 
one thousand and ninety-six, and Schenk’s one 
thousand two hundred and thirty-nine. Some of the 
Oxford manuscripts have one thousand and eighty, 
others one thousand nine hundred ®. | 
Those which I have seen, and probably the foreign 
manuscripts, may be reduced to three classes. 
First. Those which agree with Villa Nova’s text, 
With occasional various readings, and small differ- 
ences. These are of little value, and I believe ate 
most of them copied from the printed editions. 
Sxconpiy. Those which have Villa Nova’s text 
for their basis, preserving its character, yet having 
considerable additions, and alterations. 
The TH1Rp class of manuscripts contains a poe 
in which the Schola Salerni is incorporated, but 
differs entirely from the other classes, in a more 
methodical arrangement, in very great, and more 
scientific, additions. The ‘Manuscripts vary 1! 
length, but some of them contain near nineteet
