Emmerich gives similar results; thus after inoculating rabbits with 
erysipelas he found that this conferred a certain immunity against sub- 
sequent inoculation with anthrax, and also that the destruction of the 
bacteria was chiefly extracellular, and that the phagocytes made away 
chiefly with the dead bacilli. Again it is noticed by the author (H. 
Bitter) that in none of Metschnikoff 's works, nor in those of other 
writers, is it certainly proved that the bacteria are destroyed by 
phagocytes, and by these alone, and in conjunction with Nuttall he has 
proved this experimentally. 
With regard to Metschnikoff" 's experiments on frogs at high temper- 
atures, it is obvious that the fluids of the body may become so altered 
by the increased heat that this fluid is thereby no longer able to 
weaken the bacteria. 
Moreover, a series of observations has shown that anthrax bacilli 
have always suffered some damage before they became a sacrifice to the 
phagocytes. On the whole the author inclines to bring in a verdict of 
not proven. 
Physalia in the Bay of Fundy. — In the published lists of 
Medusae from Grand Manan, there is no mention of the well-known 
Portuguese-Man-of-War, Physalia arethusa. I am unaware that it has 
ever been taken from the Bay of Fundy, and up to last summer it was 
unknown to the fishermen who work in these waters. 
During the last summer (August, 1889) several specimens of this in- 
teresting Gulf Stream jelly-fish were taken off" Grand Manan and 
brought to me for study. I have also learned that many others have 
been seen in different parts of the Bay. This unusual appearance of 
these visitors from the tropics is connected with the great abundance 
of these animals all along the New England coast during the past sum- 
mer. Its presence at Grand Manan, where the pelagic fauna is decid- 
edly Arctic, is an interesting fact, as showing how far it may straggle 
from waters more congenial to its life. In this connection it may not 
be out of place to mention the fact that these Physalije were taken 
near the " Ripplings," tide eddies several miles off" the west coast of 
Grand Manan, in which is collected at certain times of the tides a 
most wonderful abundance of free-swimming life. These eddies, which 
are feeding grounds for many of the larger marine animals, are peopled 
by a rich variety of marine life of all kinds, brought into its vortices by 
the extraordinary tides for which the Bay of Fundy is famous.— J. 
Walter Fewkes.
