In addition to these, it is hoped that other Memoirs will 
be arranged for, on suitable types, such as Pontobdella, a 
Cestode and a Nematode. 
_ 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 stained 
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 
Lernea, 6d. to ls.; VII., Lineus, 6d. to 1s.; XIII., Anurida, 
1s. to 2s. ; XIV., Ligia, 6d. to 1s.; XV., Antedon, 6d. to ls. 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 1917, compiled ~ 
by Mr. Chadwick from his daily records, is not yet completed ; 
but that for the preceding year, 1916, is inserted here as usual.
