In addition to these, it is hoped that other Memoirs will 

 be arranged for, on suitable types, such as Pontobdella, sl 

 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 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 

 Lernsea, 6d. to Is. ; VII., Lineus, 6d. to Is. ; XIII. , Anurida, 

 Is. to 2s. ; XIV., Ligia, 6d. to Is. ; XV., Antedon, 6d. to Is. 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 1916, compiled 

 by Mr. Chadwick from his daily records, is not yet completed ; 

 but that for the preceding year, 1915, is 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.
