408 Mr. Snow Harris on the Electrical Discharge 
It is further stated, and it is a most important fact, that a 
seaman aloft on the cross trees, at the time, did not experience 
any sensation whatever. 
31. No. 4. The Buzzard brigantine was struck by lightning 
on the Coast of Africa in February 1838, and lost her top^gal- 
lant and topmast, under precisely the same circumstances as 
those of the Hyacinth, the lower mast being preserved by 
the chain topsail sheet 
32. No. 5. The Fox revenue cutter was struck by lightning 
in March 1818. The mast was furrowed and otherwise da- 
maged in every part except where it was coppered ; as appears 
by a minute made at the time by the master mast-maker at 
the Plymouth dock-yard. 
Now the copper usually placed about a cutter’s mast is not 
the thickness. In this case it re- 
mained perfect. 
33. No. 6. The spire of a church at Kingsbridge in Devon- 
shire was struck by lightning in June 1828, and fearfully 
damaged. This case is particularly worthy of notice. 
The lightning fell on an iron spill, a, h, supporting the 
weather-cock, about 7 feet in length and 
1 inch in diameter. On this it produced no 
visible effect, nor did any damage arise to 
the stone-work about the rod. It was not 
until the rod ceased at the point b that the 
masonry was rentf. 
34. No. 7. Extract from a letter from Lieut. 
Sullivan, of H.M.S. “ Beagle,” addressed 
to the Editor of the Annals of Electricity, 
&c., &c., relative to the protection afforded 
by a continuous conductor attached to the 
mast of H.M.S. Beagle. 
‘‘ Having considered your communica- 
tion in the Annals of Electricity on marine 
lightning conductors, containing observations on the stroke 
of lightning which fell on the masts of H.M.S. Beagle, 
I think it fair, both to Mr. Harris and the naval service, to 
describe the phaenornena I witnessed on that occasion; first 
stating, that at the time of my joining the Beagle in 1831, pre- 
viously to her leaving England, I had no acquaintance with 
Mr, Harris, and certainly no bias in favour of the conductors 
with which the ship was fitted. I may therefore claim to be 
considered an impartial observer. 
* Tliis case was given me by the commander Lieut. Fox. I was myself 
on board the vessel on her arrival. The particulars are noted in her log.

G. F. Wise, late Vicar of Kingsbridge.
