REVIEW — A REGISTER OF EXPERIMENTS- 
if our journal does not mislead us, in May 1839, that his PART I 
came out ; in May 1843, that Part II issued ; and now, in May 
1847, appears Part III : thus making intervals of exactly four 
years between the publication of each part. Some people might 
feel disposed to find fault with this tardy progression; for our own 
part, however, knowing, as we do, to what calls of business Mr. 
Turner’s time is continually subjected, and that experiments such 
as he is engaged in can only be put in practice as opportunity 
offers and leisure serves, we can well make excuse for him, if any 
be needed ; and moreover, we would rather commend than criti- 
cise any reasonable tardiness, because more ample time is thereby 
given for that sober and serious reflection which researches of the 
grave nature he has undertaken imperatively demand. 
Those who may not possess the former parts of Mr. Turner’s 
work, will find accounts given of them in vols. xii and xvi of 
The Veterinarian. For fear, however, of neither source of 
information being at hand, and in order that we may carry our 
reader on the present occasion along with us, we deem it most 
prudent, in limine , to recapitulate a little out of former accounts. 
From blood flowing out of a living animal it is on all hands 
acknowledged that a halitus or vapour is seen ascending; but no 
physiologist, either before Mr. Turner’s time or since, has advanced 
so far as to assert that a “ blood steam,” or gas , actually circulates 
through the arteries along with the stream of liquid blood. And 
what first suggested this notion to Mr. Turner’s mind, a notion 
which future and varied experience, so far from dissipating, has 
but tended more and more to brighten into verisimility — we 
repeat, what first created this “ notion,” was this : — “ Hitherto,” 
says Mr. Turner, in Part II, “ when physiologists have impri- 
soned the blood of a living animal in any large trunk — the carotid, 
for instance — for the space of two inches, between two ligatures, 
and have allowed three or four hours to elapse, they have invariably 
found the blood coagulated , and of a dark colour, upon slitting 
open the vessel. But when I undertake a sudden seizure of such 
a portion of artery of a living animal with the NEW INSTRUMENT, 
and cause an instantaneous imprisonment of its contents, in transitu, 
a result totally different is obtained*.” 
“ Harvey gave circulation to the blood ; Hunter, life to it. 
Turner would give gas to it:” so says our review of Part lit: 
“ the actual (or assumed) fact being,” in Mr. Turner’s own words, 
“ that there is a joint gaseous and sanguineous circulation .” 
With thus much premised, we shall come at once to the under-
