THE EFFECTS OF A FLASH OF LIGHTNING. 81 



FIG. i. S. South side. N. North side of ash tree. The 

 whole spaces included at a and b were entirely denuded 

 of bark. At / the limb ended in a dead stump, of 

 which several feet were broken off and hurled to a 

 considerable distance in a S.E. direction. C. A clod 

 of turf thrown up and turned over from the hole <?. 



5. A small tree close to No. 6. From d, where the traces 

 of the flash end in No. 5, there is an apparent jumd 

 to e in No. 6, whence it continues sinuously upwards. 

 The space between the red lines at g. was entirely 

 denuded and deeply channelled. 



PLATE VI. 



FIG. 4. The whole of the space at a was denuded of bark. 

 At / the direction of the stroke is continued on the 

 other side, appearing again at g, passing on to the 

 other limb and so upwards. At h, tt are also traces 

 as of violent blows given to the bark. 



7. The stroke indicated here by the red line was deeply 

 channelled. At c there was a leap to b, a branch 

 crossing and in contact at a little distance with the 

 branch c. 



,, 8. A small ash tree (one of a group). At e the bark was 

 thrown off, and a small hole was made just above it. 

 No further trace of a stroke on this tree, excepting on 

 the dead limb at d, upwards, but not to its extremity.
