Dr. J. R. Jounson intends shortly to 
publish, Further Observations on the 
Medicinal Leech, including a transla- 
tion of the very interesting Memoir 
Jately transmitted to him by M. Noble, 
physician at Versailles, and a reprint 
from the Philosophical Transactions of 
“‘ Observations on the Mode of Propa- 
gation of the H. vulgaris, or common 
rivulet Leech.” The work will be 
illustrated by two or three engravings, 
one of which will represent the cocoon’ 
of the medicinal leech (with the en- 
closed young), which nearly equals in 
size and figure the cocoon of the silk- 
worm. This fact will completely set 
at rest the long-disputed question, as 
to whether the medicinal leech is ovi- 
parous or viviparous. The H. vulgaris 
Dr. J. has found to produce its young 
in a similar manner, that is, the ova 
are enveloped in a gelatinous mass, 
and are, at the time of their exclusion, 
received into a membranous bag or 
capsule, or what we may term cocoon, 
formed exterior to the body; from 
which the parent animal afterwards 
withdraws the anterior portion of its 
body. Ina period of about six weeks, 
the young emerge from the opening 
at each extremity of the cocoon, where 
there is but little resistance opposed’ 
to their passage, and which, it would 
appear, were left for this purpose, by 
the very singular manner in which 
these capsules are formed and depo- 
sited.
