In addition to these, it is hoped that other Memoirs will 
be arranged for, on suitable types, such as Pontobdella, a 
Cestode, a Nematode, and a Cirripede. 
As the result of a slight fire in the Zoology Department 
of the University, a portion of the stock of L.M.B.C. Memoirs 
has been partially destroyed. There are a certain number 
of damaged copies of some of the Memoirs which are staimed 
or singed externally, but are still quite usable, and are suitable 
for laboratory work. The Committee has decided to offer 
these at prices ranging according to the condition from one- 
half to one-fourth of the published prices, as follows :— 
Memoir I., Ascidia, 6d. to 9d.; VI., Lepeophtheirus and 
Lernsza, 6d. to 1s.; VII., Lineus, 6d. to ls.; XIII., Anurida, 
Is. to 2s.; XIV., Ligia, 6d. to 1s.; XV., Antedon, 6d. to 1s. 3d. 
Orders for these damaged copies should be sent to Professor 
Herdman, the University, Liverpool. New copies of any of 
the Memoirs should be ordered from Williams & Norgate. 
The diagram of sea and air temperatures for 1915, compiled 
by Mr. Chadwick from his daily records, is not yet completed ; 
but those for the two preceding years, 1913 and 1914, are 
inserted here to show the general similarity of the two curves 
along with a few points of divergence, and to demonstrate again 
the manner in which the temperature of the sea lags behind 
that of the air in both winter and summer. The annexed 
charts show clearly the points of agreement and of difference 
between the two years.
