NOTES AND MEMORANDA. 
From the instant that the bacteria penetrate into the blood (by 
taking the blood of a rabbit inoculated hours previously from three 
punctures made in the inside surface of each fore-leg, and injecting 
fifteen drops of it in the jugular of another rabbit, I caused the death 
of the latter) the phenomena are as though the injection had been 
made in the vessels, that is, as in the second case, allowance being 
made for the parasites constantly supplied by the ganglia which were 
the first receptacles. 
Finally, in the case in which vascular ruptures supervene after 
the penetration of the bacteria into the blood, each rupture lets a 
greater or less number of bacteria escape, which there act as true, deep 
inoculations, which are followed by the same disorders as in sub- 
cutaneous inoculation, that is to say, infiltration, penetration into 
the ganglia, and return to the blood. But the disorders in this case 
are so numerous and severe that the animal dies before the capillary 
emboli are formed. 
The knowledge of these facts may throw some light on the mode 
in which the bacteria j)enetrate in the case of spontaneous Antlirax ; it 
enables us to determine in what part of the economy and through what 
channel the parasites are introduced.^ 
OncJiopora liirsuta . — Mr. W. H. Weightman, of the Liverpool Micro- 
scropical Society, has shown that, besides the common tubes, described 
and figured by Mr, Busk in the ‘ Quarterly Journal of Microscopical 
Science’ for 1855, there are also at the base of the lowest in- 
ternode a number of radical tubes, which Mr. Busk seems to have 
overlooked. They are each upwards of one-tenth of an inch in length, 
hollow like the others, but spirally twisted, and not jointed. The 
extremity of each of these radical tubes is dilated, and of a crozier-like 
form, and of a much darker colour than the shaft. Within the crozier- 
like tip there appears to be a dark secretion, Avhich in the living con- 
dition was probably fluid, but the purpose of which he is quite 
ignorant of. 
The calcareous cell of Onchopora is somewhat granular in sub- 
stance, and is minutely punctured, and acts with some degree of 
energy on polarized light, hut not so much so as the corneous tubes, 
which are quite brilliant when viewed with polarized light ; the 
radical tubes are somewhat less so. 
Spore Nomenclature. — In regard to an article on this subject in 
the ‘ Bot. Zeitung,’ by Messrs. A. de Bary and E. Strasburger, the 
‘ Bulletin’ of the French Botanical Society (vol. xxv. p. 32) says : — “ The 
Acetabularia furnishes a new example of conjugation between zoospores, 
interesting because of the terminology it gives the authors an oppor- 
tunity of proposing. The hiciliated and sexual autherozoids which 
are capable of copulation receive from them the name of ‘ gametes’ and 
the products of their copulation that of ‘ zygote’ instead of isospore or 
zygospore. They are anxious to remove from this name the root- 
spore, reserving this term for the reproductive body which does not 
result from a fecundation.”
