covered, and though repeatedly, to all appearance, killed on that and 
the three following days, she did not die until she had laid 298 eggs. 
Many examples were given by the gentlemen present of the extrusion 
of eggs by moths, not only before death but even in articulo mortis 
and when the thorax was stiff, and to all intents dead ; so great was the 
effort of nature to propagate the species. There was also a curious 
circumstance connected with the eggs themselves, the first 175 had 
changed to the ordinary chocolate colour, while the rest had remained 
pink ; this in nowise affected their vitality, because many of them, 
equally with the others, had hatched. 
Mr. Wownror then read a paper on the Annual Excursion to 
Arundel, on June 30th, in which the chief incidents of the day, and

and the Mayor of Arundel.
