Note 2921 — BOOK XXXI. REMEDIES DERIVED FROM THE AQUATIC PRODUCTIONS.
John Bostock translation
See B. ii. c. 43. Ajasson remarks, that the electric fluid, forming lightning, escapes from the clouds through causes totally independent of water. Still, Pliny would appear to be right in one sense; for if there were no water, there would be no clouds; and without clouds the electric fluid would probably take some other form than that of lightning.
