VII. An Account of an Experiment^ touching an 
Attempt to produce Light on the Infide of a 
Globe-Glafs lind with melted Flowers of SuU 
phur^ as in the Experiments of Sealing-Wax 
. and Titch, Sy Mr. Fr. Hauksbee, F, 5^. 5, 
N Otwithaanding Sealing-wax and Pitch afford fuclr 
furprizing Phenomena, rendring the Form of Bo- 
dies viuble thro’ their Opake Subftances; under the Cir-
