We have examined the records of the two last years, 
(1) as these are the years in which the plankton has been 
most carefully and fully collected at Port Hrin, and (2) in 
order to have the results for a second year to compare 
with those of the one chiefly under consideration. 
In 1908, no observations were recorded under 
K.N.M.; and the maximum number (one-seventh of the 
total), with maximum intensity (one-seventh of the total), 
were under W. In that year the following four are 
markedly stronger than the rest:—N., H.S.E.,S.W., and 
W., and the following three are as markedly weaker :— 
N.E., E.N.E., and 8.S.E. In January and March the 
records show wind well distributed round the compass, 
but February, April, May, September and October show 
half the compass with almost no records. The most 
pronounced winds are the W. and W.N.W. in February, 
the W. in August, the H.S.E. and S.E. in October, and 
the W. in November. | 
In 1907, there was no point without any observations, 
aud the maximum number (one-sixth of total) with 
maximum intensity (one-sixth of total) were under W. 
The highest records were under E.S.E., 8.W., W., and 
W.N.W., and the lowest were under N.E., E.N.E., and 
S.S.H. June, August and September show half the 
compass with almost nu records. The most pronounced 
winds were the W. in January, August and December, the 
W.N.W. in March, the E.S.H. in September and October, 
and the 8.H. in December. 
Iixamination of the tables, or of the diagrams for the 
two years 1907 and 1908 taken together, shows that there 
are four points—H.N.E., $.S.E., W.S.W., and N.N.W.— 
which are weak in intensity as well as in number of 
observations, and that consequently the year’s wind 
appears naturally to be divided into four blocks separated 
by these weak points (see figs. 2 and 3) :—
