Mould on Lepidoptera. — Of all the ene- 

 mies with whicli Lepidopterists have to 

 contend, I think mould is the greatest. It 

 first makes its appearance on the antennae 

 of the butterfly or moth, coating them 

 with a light feathery substance, and finally 

 spreads over the whole body and wings, 

 discolouring them and ending in their 

 total destruction. How is it to be got rid 

 of ? Surely there is some effectual remedy 

 for stopping this infection. If some old 

 hand in the art of insect preserving would 

 explain this mystery, he would confer a 

 great boon to amateurs in this delightful 

 art ; as I am myself aware, from bitter 

 experience, ' that numbers of insects are 

 put aside from a collection as useless things 

 because they have become mouldy. I keep 

 my specimens in a cabinet well fumigated 

 with benzine, and placed in a dry, airy 

 room, free from anything pertaining to 



moisture or dampness, and can by these 

 jjrecautions succeed in keeping clear of 

 grease and mites ; but mould will find its 

 way to my treasures in spite of every pre- 

 caution, disfiguring their wings and ren- 

 dering them unsightly objects. I have 

 heard that spirits of wine, applied with a 

 camel-hair brush to the infected insect, is 

 a means of stopping mould, but should 

 not like to try it unless confirmed by some 

 one who can vouch for its efficacy. — F.

Oolitic Fossils. — I have duplicates of the 

 above which I can exchange for Silurian,- 

 or Carboniferous fossils. Lists of fossils for 

 disposal, or the fossils themselves must be 

 forwarded to John Williams, Esq., 16,
