Tue year 1893 was one of exceptional interest to the marine 
zoologist. During the first two months Plymouth experienced a 
continuous succession of heavy gales, but towards the middle of 
March the winds became lighter, and the sea, which had been running 
remarkably high outside the breakwater, subsided. From that time 
onwards till the middle of September we enjoyed six months of the 
most delightful weather,—a period, with scarcely a break, of calm 
seas and almost cloudless skies. Under the influence of the great 
heat the temperature of the Channel waters rose continuously, until in 
August it had attained a point unprecedented for quarter of a century ; 
and it was of the highest interest to observe the effect of this hgh 
temperature, and of the prolonged calmness of the sea, upon the 
floating population of the neighbouring portion of the Channel. 
Numbers of semi-oceanic forms which rarely reach our shores arrived 
in remarkable profusion. In June the tow-nets were crowded with 
Salps, while towards the latter end of August they were almost 
choked by masses of living Radiolaria. 
Even the bottom fauna was influenced, as was shown by the 
extraordinary abundance in the Sound thoughout the spring and
