Quid sit pulchrum, quid turpe, quid utile, quid non. — II or. 
A Register of Experiments , Anatomical , Physiological , and Pa- 
thological, pei formed on Living Animals; disclosing New 
Views of the Circulation of the Blood, fyc. By James 
Turn er, V.S., Regent-street, London. Part II. Longman 
and Co. 
Un appalled by the great names of Harvey and Hunter, 
our professional brother, Mr. James Turner, has made his 
second* appearance, and still “ in battle array,” in the very field 
of science, wherein those distinguished medical heroes acquired 
their immortal fame. Harvey gave circulation to the blood ; 
Hunter, life to it ; Turner would give gas to it. “ Harvey,” says 
Mr. Turner, “ recognised a current of liquid only through the 
arterial channels ; whereas there exists also a gaseous current, of 
equal volume , traversing the same vessels in conjunction at one 
and the same time.” And, in another place — <l The greatest phy- 
siological error which has been committed since the days of 
Harvey is, the theory that the caliber of the arteries and veins 
of a healthy man are maintained by the circulation of sheer 
blood : the actual fact is, that it is a joint gaseous and sanguine- 
ous circulation .” These quotations making the meaning and 
object of our author clear beyond the possibility of doubt, let 
us now inquire into his proofs of the presence of air or gas ; 
and after that , enter into some examination of his explanation of 
the phenomenon. 
In limine , however, it will be right to inform our reader that 
Mr. Turner is in possession of an instrument, or rather a machine, 
consisting — to use his own words — tc of a mechanical appa- 
ratus, by the instantaneous spring of which an inch and a half, 
or more, of a denuded artery — the carotid, for instance — of any 
living healthy animal is suddenly seized within a barrel ; the 
instrument being so constructed that each extremity of the barrel 
acts simultaneously in the constriction of both the exposed 
extremities of the vessel ; the caliber of the barrel being suffi- 
ciently ample to avoid the slightest compression of the imprisoned 
artery, except at both its extremities, which are hermetically 
sealed by instantaneous compression.”
