7922, _lison_, _lion_, _giroun_, _enviroun_, _leçon_, _noun_, 16801 ff. (yet _lisoun_ is also found, 24526). On the whole, so far as the rhymes of the _Mirour_ are concerned, the conclusion must be that the uniformity is broken chiefly by the influence of those words which have been noted as written always, or almost always, with _-on_. In the _Balades_ and _Traitié_, however, the two terminations are more equally balanced; for example in _Bal._ xxxv we find _convocacion_, _compaignon_, _comparison_, _regioun_, _noun_, _supplicacion_, _eleccion_, _condicioun_, &c., without any word of the class referred to, and _Traitié_ xii has four rhymes in _-on_ against two in _-oun_. On the whole I am disposed to think that it is merely a question of spelling, and it must be remembered that in the MSS. _-oun_ is very rarely written out in full, so that the difference between the two forms is very slight even in appearance. vii. The Central-French _u_ was apparently identified in sound with _eu_, and in some cases not distinguished from _ui_. The evidence of rhymes seems quite clear and consistent on this point. Such sequences as the following occur repeatedly: _abatu_, _pourveu_, _deçu_, _lieu_, _perdu_, _salu_, 315 ff.; _truis_, _perduz_, _Hebrus_, _us_, _jus_, _conclus_, 1657 ff.; _hebreu_, _feru_, _eeu_, _tenu_, _neveu_, _rendu_, 4933 ff.; _plus_, _lieus_, _perdus_, _conçuz_, _huiss_, _truis_, 6723 ff.; _fu_, _lu_ (for _lieu_), _offendu_, _dieu_, in _Bal._ xviii; and with the ending _-ure_, _-eure_: _demeure_, _l’eure_, _nature_, _verdure_, _desseure_, _mesure_, 937 ff.; _painture_, _demesure_, _aventure_, _jure_, _hure_, _controveure_, 1947 ff., &c. This being so, we cannot be surprised at such forms as _hebru_ for _hebreu_, _lu_ for _lieu_, _fu_ for _feu_, _hure_, _demure_, _plure_, for the Continental French _heure_, _demeure_, _pleure_, or at the substitutions of _u_ for _ui_, or _ui_ for _u_ (_eu_), in _aparçut aparçuit_, _huiss huss_, _plus pluis_, _pertuis pertus_, _puiss pus_, _construire construre_, _destruire destrure_, _estruis estrus_, _truis trieus_. As regards the latter changes we may compare the various spellings of _fruit_, _bruit_, _suit_, _eschuie_, _suie_[G], in Middle English. It should be mentioned however that _luy_ rhymes regularly with _-i_ (_-y_), as _chery_, _servi_, _dy_. In some cases also _ui_ interchanges with _oi_, as in _buiste_ beside _boiste_, _enpuisonner_ beside _poisoun_. This is often found in early Anglo-Norman and is exemplified in M.E. _buyle boyle_, _fuysoun foysoun_, _destroye destruien_. On this change and on that between _ui_ and _u_ in Anglo-Norman see Koschwitz on the _Voyage de Charlemagne_, pp. 39, 40.
