 the water, it appeared that all the luminous matters, 

 such as Zoophytes and Mollusca with their spawn,

 from the abundance of food to be found. On the 

 contrary, the sea in. the neighbourhood of the north 

 west coast of America is clear and transparent, and 

 nothing is found in it except here and there a single

 1825, from March to the middle of August, we had 

 an almost uninterrupted continuation of fine wea

 one fine day to fourteen cloudy or wet ones. &quot;We
