down each of these without any injury to the building, except starting 
afew slates near the ridge post. Now, what appears singular in this 
case, is, that no person out of nearly three hundred, officers and con- 
victs, was in the least injured, although almost every one was more 
or less affected by it. Nearly all of these persons had either a steel- 
ed hammer, a musket with bayonet fixed, or some metallic utensil in 
their hands. Within a yard of my situation, is an armory with thirty 
guns, and as many steel pointed pikes—the points and bayonets point- 
ing up. I can account for our escape, only by supposing that the 
fluid was attracted by so many different objects, on all parts of the 
building, and all over the yard, that it divided itself just before it 
reached us, and passed off in such small quantities as almost to lose 
its effects. 
It is singular that men standing five hundred feet distant from me, 
should be affected in the same degree. I suppose that one hun- 
dred tons of iron are exposed on the different buildings, in grates, 
doors, pillars, &. &e. One of the officers had a saw in his hand, 
which, he says, seemed to be “ light red fire.” Another was stoop- 
ing and picking up nails from the floor, and the instant after the 
flash, found himself standing bolt upright, with his hands tightly 
clenched together. The effects of this bolt were felt over a surface 
of one hundred and seventy two thousand five hundred feet, in near- 
ly the same degree, without any permanent injury being sustained.

2. Electro-galvanic phenomena.*—Singular—On Wednesday 
of last week, while the workmen were soldering the iron water pipes 
in Water street, electric shocks were produced to such a degree as 
to cause them to discontinue their labors through the remainder of 
the day. Several of our citizens who were standing by, got into the 
ditch, and tried the experiment, when the effect was the same on all. 
The pipes are united in the following manner :—they are nine feet 
long, perfect cylinders, with a bore of six inches, and a bowl at one 
end four inches deep. At the spring, is a funnel pipe which is in- 
serted into the bowl of the succeeding pipe ; the spigot end of which 
1s inserted into the bowl of the next, and so on. When fifty or one 
hundred pipes are laid down in this manner, the process of soldering 
commences. This is done by first ramming into the joint a few 
strands of rope-yarn, and then applying clay around the joint, leaving
