Bede referred to by J.MN. may have been in a tract _De Minutione Sanguinis
sive de Phlebotomia_; (which occurs in the folio editions, Basle, vol. i.
p. 472.; Colon., vol. i. p. 898.). In the enumeration of the veins from
which blood may be taken, he says,--

"De brachio tres, _qui per totum corpus reddunt sanguinem_, capitanea
linea, matricia, capsale."

The subject of bleeding is again referred to in _Eccl. Hist._, vol. iii,
but not to the purpose.

_True Blue_ (Vol. ii., p. 494.).--From documents relative to the wars of
the Scottish Covenanters, in the seventeenth century, it appears that they
assumed _blue ribbons_ as their colours, and wore them as scarfs, or in
bunches fastened to their _blue bonnets_ and that the border English
nicknamed them "_blue caps_" and "jockies." Hence the phrase, "True blue
Presbyterian."

_Cherubim and Seraphim._--Why are the cherubim represented as a human head,
with the wings of a bird? And why have the seraphim no bodily
representation? What, in fact, is the supposed distinction between them?
