whthalene was melted and poured in the lids and allowed to run around the edges 
rden. Carbon bisulphid was put in a small tin box lid in each box. The boxes 
osed and allowed to stand over night. The next day the tins were removed and 
chin tt boxes were sealed by means of half inch white adhesive tape. The screws 
loosened to allow the hooks to pass over the tape. The tape was stuck around 
ces over the junction of ths boxes and lids. Each box was wrapped with paper 
ked in a barrel containing excelsior. The collection was shipped to Browns~
