Observations on Natural History made in Neiu England. By Mr. Benj. Bulli- 

 vant, in a Letter to Mr. Peliver, F.R.S. N° 240, p. 167. 



I made the same remark, you do about the plague of the back, that it is 

 greatly distant from an empyema. I have experienced it more than once, 

 it seems more of a cholick, yet is undoubtedly a nervous dolour. The country 



people have learned of the Indians to steep castoreum in rum, and so cure it. 



The fire-flies seem to be a flying glow-worm, the lustre is placed as in a glow- 

 worm. Kill the fly, and you find the scintilla a small jelly-like substance, 

 which, separated into atoms, gives still in the dark a lustre proportionable to 

 the magnitude of each atom. I saw butterflies' eggs that were testaceous, and 

 near as large as a wren's, most gloriously bestudded with gold and silver ; at 

 Rhode Island the mowers find them in the grass, and they hatch in the windows, 

 and are a sport for children. — Tortoises are amphibious, I have found their eggs
