Book IV

. As Mommsen pointed out, the archetype from which the existent MSS. were copied must have had some of the leaves containing these letters transposed. These were copied in our MSS. in the wrong order, and were so printed in earlier editions. In the text Mommsen’s order, with some recent modifications introduced by Holzapfel, has been adopted; and the figures in the margin denote the place of the transposed passages in the older editions, the Roman figures denoting the letter from which each

## particular passage has been shifted and the Arabic numerals the section

of that letter.

The following signs have been used in the apparatus criticus:—

_M_ = the _Codex Mediceus_ 49, 18, written in the year 1389 A.D., and now preserved in the Laurentian Library at Florence. _M_^1 denotes the reading of the first hand, and _M_^2 that of a reviser.

Δ = the reading of _M_ when supported by that of the _Codex Urbinas_ 322, a MS. of the 15th century, preserved in the Vatican Library.

_E_ = _Codex Ambrosianus_ E, 14, a MS. probably of the 14th century, in the Ambrosian Library at Milan.

_N_ = the _Codex ex abbatia Florentina_ n. 49 in the Laurentian Library, written in the 14th or 15th century.

_P_ = No. 8536 of the Latin MSS. in the Bibliothèque Nationale at Paris, a MS. of the 15th century.

_R_ = No. 8538 of the same collection, written in the year 1419. These four MSS. _E_, _N_, _P_, _R_, with some others form a separate class; and

Σ = the reading of all the MSS. of this class, or of a preponderant number of them.

_C_ = the marginal readings in Cratander’s edition of 1528, drawn from a MS. which is now lost.

_Z_ = the readings of the lost _Codex Tornaesianus_, _Z_^b denoting the reading as preserved by Bosius, and _Z_^l that testified to by Lambinus.

_I_ = the reading of the _editio Jensoniana_ published at Venice in 1470.

_Rom._ = the edition published at Rome in 1470.
