/^^N landing at Harwich from the steamer, after accompanying the 

 ^^ members on the excursion on the Orwell and Stour on July 

 25th, 1 89 1 (see page 247), 1 found that I had about an hour's spare

 shore was accordingly undertaken, and the following algas were 

 noticed, the shore on the Dovercourt side of the little breakwater 

 being the richest part.
