Paley’s comment is aXiio. So Herm. for oXujj or aXtov. 
See above on v. 170. Musgrave sliows from Pollux, i. 49 
that the chemical effect of the sunlight on garments dyed 
with the sea-purple is to refresh and heighten the hues,

From this property of the sea-purple ^Fschylus calls it KtjKlg 
Tray KaivicFTog, Agam. 933, “ capable of being entirely renewed 
when faded.” The passage of Musgrave (and of Pollux) 
referred to by Paley is as follows : 
^oiviKag — TreTrXovg. Purpureas vestes. Has enim soli 
exponere mos erat ad renovandum tincturse splendorem.

71 (3a(j)7i Kal r) aKrlg avTTiv avaTrvpaevei, koX nXelw TTOiet Kal 
(paidporipav ri)v avy^v.” The meaning of this passage I take 
to be — “ The purple dye delights in association with the sun, 
and the solar beam reddens it and makes more intense and 
more dazzling its splendour.” 
Mr. Charles Bailey, F.L.S., exhibited specimens of 
Ophioglossum vulgatum, L., var. j3. ambiguum, Coss. et 
Germ., which he had collected in July last on damp sandy 
ground at the foot of the sandhills, on the land side, one 
mile west of Dyffryn railway station, between Harlech and 
Barmouth, in Merionethshire. This plant has been figured 
on plate 46 of “British Ferns,” by the late Sir William 
Hooker, and the Welsh specimens agree well with this 
figure, though generally smaller in size. The variety amhi- 
guum was originally detected more than twenty years ago 
in the neighbourhood of Paris, and was found, shortly after- 
wards, in one of the numerous “ laiches” at Arcachon. It 
was first noticed as a British plant by Dr. J. T. Boswell, 
who detected it in the Orkney Islands, and Mr.Curnow has 
recently distributed specimens, through the Botanical Ex- 
change Club, from the Scilly Islands.
