sage from an eye-witness of similar occurrence at Porebunder on the 

 coast of Khattywar, where red water is extremely common, viz, the 

 color of the sea-water on Saturday evening last, the 27th October 

 1849, was changed from its usual tint to a deep red, emitting a 

 nrost foul smell ; the fish speedily were all destroyed, and were 

 washed upon the beach in large quantites kc. &c. " (Proceedings" 

 Bombay, Geograph. Soc, lot. cit.) ; we cannot help ascribing this, 

 independently of the conjecture of the narrator that it might be 

 owing to some sub-marine eruption of mud &c," to the process of 

 oleaginous development and change of color abovementioned in 

 some animalcule, most probably Yeridinium ; and of realizing, at 

 the same time, the (to me) previously incomprehensible Mosaic 

 account of the plague of Egypt, given in the following verses : — 



" and all the waters that uere in the river were turned into blood." 



" And the fish that was in the river died ; and the river stank, 

 and the Egyptians could not drink of the water of the river ; and 

 there was blood throughout all the land of Egypt." — ( Exodus 

 Chap. VII, Vs. 20 and 21 J
