The unborn child .
The name of embryo is sometimes given to it ;
but ,
although the terms are occasionally used indiscriminately ,
the latter is more frequently employed to designate the state of an unborn child during the first three months after conception ,
and by some until quickening .
A foetus is sometimes described by the uncouth phrase of infant in ventre sa mere .
2 .
It is sometimes of great importance ,
particularly in criminal law ,
to ascertain the age of the foetus ,
or how far it has progressed towards maturity .
There are certain signs which furnish evidence on this subject ,
the principal of which are ,
the size and weight ,
and the formation of certain parts as the cartilages ,
bones , &
c .
These are not always the same ,
much of course must depend upon the constitution and health of the mother ,
and other circumstances which have an influence on the foetus .
The average length and weight of the foetus at different periods of gestation ,
as deduced by Doctor Beck ,
from various observers ,
as found by Maygrier ,
is here given .

The discordance apparent between them proves that the observations which have been made ,
are only an approximation to truth .
4 .
It is proper to remark that the Paris pound poids de marc ,
which was the weight used by Maygrier ,
differs from avoirdupois weight used by Dr .
Beck .
The pound poids de marc ,
of sixteen ounces ,
contains 9216 Paris grains ,
whilst the avoirdupois contains only 8532 .
5 Paris grains .
The Paris inch is 1 .
065977 English inch .
