The Bloivlng of Fire by the Fall of Water. By the same. 



N" 2, p. 25. 



In the brass works of Tivoli near Rome, the water blows the fire, not by 

 moving bellows, but by affording the wind. See fig. 1, pi. 1 ; where A 

 is the stream ; B the fall of it ; C the trunk into which it falls ; L G a 

 pipe ; G the orifice of the pipe, or nose of the bellows ; G K the hearth ; 

 E a hole in the pipe ; F a stopper to the hole ; D a place under ground, by 

 which the water runs away. Upon stopping the hole E, there is a per- 

 petual strong wind issuing forth at G. But G being stopped, the wind rushes 

 out so vehemently at E, that it will support a ball playing above the hole 

 there. 



Aji Extract of a Letter, containing some Observations , made in the 

 Ordering of Sillt- Worms, communicated hy Mr. Dudley Palmer, 

 from Mr. Edward Dioge^. N° 2, p. 26. 



I herewith offer to your Society a small parcel of my Virginian silk. What 

 I have observed in the ordering of silk-worms, contrary to the received 

 opinion, is : 



1 . That I have kept leaves 24 hours after they are gathered, and flung water 

 upon them to keep them from withering ; yet when (without wiping the leaves) 

 I fed the worms, I observed, they did as well as those fresh gathered. 



2. I never observed that the smell of tobacco, or smells that are rank, did 

 any ways annoy the worms. 



3. Our country of Virginia is very much subject to thunders: and it has 

 thundered exceedingly when I have had worms of all sorts, some newly hatched^ 

 some half way in their feeding ; others spinning their silk ; yet I found none 

 of them concerned in the thunder, but kept to their business, as if there had 

 been no such thing. 



4. I have made many bottoms of the brooms (in which hundreds of worms 

 spun) of holly ; and the prickles were so far from hurting them, that even from 

 those prickles they first began to make their bottoms.
