and propagate, not only with their races by 
father and mother, but with themfelves, and 
produce offspring that can alio pair and per- 
petuate their varieties. But it muft be owned, 
that the produce of thefe mongrels- is not fo 
certain nor fo numerous by any means as in the 
pure fpecies : they feldom hatch more than once 
in a year, and often lay eggs that are addle. 
The fuccefsful production depends on many 
little circumflances which cannot be difcovered, 
far lefs pointed out. It is laid, that among 
thefe mules there are always many more males 
than females. “ A female Canary-Bird and a 
Gold-Finch, fays Father Bougot, produced in 
the fame year, at three hatchings, nineteen eggs 
that were all fertile ; among the nineteen there 
were only three females, the other fixteen were 
males.” It is to be wilhed that this faCt could 
be afcertained by repeated obfervations. It 
remains therefore to determine by experiment, 
(and this will not be difficult) how many 
males and how many females are produced in 
the pure fpecies of the Canary-Bird, and then 
to obferve if the number of males is greater in 
the mongrels that proceed from a cock Gold- 
Finch and a female Canary-Bird. The reafon 
that inclines me to believe this is, that in gene- 
ral the male has more influence than the fe- 
male on the ftrength and quality of the differ- 
ent races. Befides, thofe mongrel birds which
