phthalene cones which frequently "go adrift" and do much damage to pinned

‘this Station we use for storages purposes great numbers of cigar boxes and we 
rt the best method of preventing the ingress of any "Museum pests" is to brush 
paraffin about corners and edges of boxes used for such purposes. We have 
sfully stored large quantities of Entomological material and find that after 
ing down the lid with a tack that the melted paraffin brushed about the corners
