Church . — The Polymorphy of 
courtesy with which the resources of the Station have always 
been placed at his disposal by the Director, Mr. E. J. Allen, 
he would wish to draw the attention of English algologists 
to the facilities afforded by the geographical position of the 
Plymouth Laboratory for the study of our native Algae. 
Grateful acknowledgments are also due to Mr. E. A. Batters 
for kind assistance on many out-of-the-way points not easily 
obtained from the literature. 
Postscript . — Since writing the above, Dr. P. Mayer kindly 
informs me that sea-temperatures taken on different days at 
Naples during the months December, 1897, and January, 1898, 
for localities in which Cutler ia is known to occur, ranged 
between 13-5° and 13*9°. This adds confirmation, therefore, 
to the data obtained at Plymouth, which tended to show 
that the young Cutleria-thdMus vegetates normally between 
o o 
12 -14 .
