8. 8. 8. 8. The Longitudinal Sinus seen in its whole length *.
9. 9. 9. The superficial Veins of the Cerebrum, entering the longi-
tudinal Sinus.
10. The Lateral Sinus of the left side, where it is opened by the
general section.—Here then is a union of the great Sinuses of
the Brain 5.
11. The Fourth Sinus, which lies betwixt the angle of the union
of the Falx and Tentorium.
* Superior, or Sagittal Sinus, or third Sinus, Ridley. The lateral Sinuses being the
first and second, the ancients counting according to what they thought to be the
course of the blood, viz. from below upwards.

Some sav, " The fourth Sinus, or Torcular," others speak of the Longitudinal Sinus
as the Torcular—The fourth Sinus is too insignificant for us to believe that the an-
cients could suppose the compression of it to send the blood through the head. It
is more natural to suppose, that the large irregular cavity formed by the union of
the Sinuses, according to our best authors, should be called the Torcular Herophili.
The idea was, that the blood ascended by the Jugular Veins, entered this cavity,
and was so compressed bv the action of the Dura Mater, that as from a Ventricle it
was sent through the other Sinuses of the Brain. It was conceived also that the Tor-
cular prepared the blood for the Brain, as the right Auricle was supposed to prepare
the blood for passing down into the Liver. How can any author be precise upon
this point, when these arc the words of Vesalius, the best commentator on Galen;
" Videtur namque Galenus modo huic, modo illi parti Torcularis nomen accommo-
" dare : uti sane utrumque Torcular dici, nihil obstat."
