JarN 0 i. 12 Chefnuts in mutton fuet. 
2. 12 D°. in bees- wax and mutton fuet, 
equal quantities. 
3. 12 D°. in bees- wax. 
4. 12 D°. in bees- wax and yellow rofin, 
equal quantities. 
Thefe fubftances I melted 5 but did not pour them 
among the chefnuts, till I could bear my finger in 
them without the lead: fenfible uneafinefs, which I

of them, I broke all the jars on the iid of November

very intelligent in thefe matters, and found, that jar 
N° 1. which contained the chefnuts immerfed in 
mutton Juet y proved all rotten , attended with a very

mofl of them found and firefly and their kernels as

Thefe were inclofed in half bees-wax, and half mut-
