Of ANT S. 51 
might be expeCted. It is alfo an additional MiC 
fortune that they will not, like moft other Aurelia^ 
come to any Perfection under a Glafs. 
When the Nymphs have attained this perfeCt 
Form of Ants, they continue their White Com¬ 
plexion about three Weeks; and all the while do 
not appear to have the leaft: Spark of Life or Mo¬ 
tion, but refemble fo many little Images formed of 
Alabafter.Upon their approaching nearer to MaUu 
rity fome of them turn yellow, others brown. * 
When they have been thus difcoloured for feven or 
eight Days, they begin to free themfelves from Im~ 
prifonment. You will firfi: of all perceive a weak 
and feeble Tendency to Motion in their Legs and 
Antennae. In fome Days more the Ants will appear 
in their proper Chara&ers, and be in all Re- 
fpedts complete, except as to Colour, wherewith 
they are not perfectly ftained for a confiderable 
Space. 
* The juft Progrefs of Ant-Eggs,VermicIes, Nymphs, 
&c. cannot be precifely dated, as they will not arrive 
to Maturity under Glaffes, C5V. Swammerdam has alfo 
mentioned this Misfortune. Multoties fui conatus, ut
