CASES OF LIGHTNING DISCHARGE. 255 
The Muka Head case 4 October 9th, 1897, ) affords another 
example of the inefficacy of the old- fashion ed single conductor, 
which was supposed to ‘bisa a building of any size if only it 
were high enough, and had nicely sharpened points and an earth 
resistance ger К a fraction of anohm. From the interes- 
ting report by Mr. Wills,* the Lighthouse keeper, it would seem 
that a fash struck the conductor, leaving evidence by tearing 
off a gunmetal brace about half way up. The discharge then left 
stationed there are exceptionally freakful dud violent. He 
€— occasion, a discharge passed through a large earthen- 
r, making one ho e of several inches in diam eter, and a 
second of less than one БОН, and finally excavating part of the 
floor near the jar 
An attempt to explain the conditions which serve to brin 
about results like these is not within the scope of the present 
notes, but the writer may, perhaps, be permitted to invite 
further lightning notes, accompanied where possible by photo- 
graphs, ‘Such records are of the greatest possible assistance in 
promoting the general knowledge of a series of phenomena 
about which there is still muck to be discovered.
