 Many and long have been the papers written to prove the presence of an auditory 

 apparatus in that portion of the articulata to which the common term "insect" is 

 applied. In some of the articulata for example, in the crustaceans we find this 

 apparatus present, though in a very rudimentary state, consisting of a simple ves- 

 tibule. We might, therefore, by analogy, infer its presence in others of the same 

 class; besides, the majority of the insect tribe are noted for giving utterance to 

 sounds of various sorts, and these, vibrating through the air, produce an evident 

 effect upon other insects, and are even, in some cases, responded to, as in the bee. 

 Now, one is naturally led to conclude, that an insect which can appreciate a certain 

 sound or vibration must possess organs for their reception, which organs would be 

 analogous to the ear in man. The aim of this paper is to prove the presence of 

 these organs in the Culex Mosquito ; and this, we think, has been done very satisfac- 

 torily ; and we have little doubt, if this subject were followed up, that the majority 

 of the articulata would be found possessing an auditory apparatus rudimentary, it 

 might be, but still present. (W. Webb, M.D.) On the Noctiluca Miliaris ; (P.

No. 147, January : (Robert Warrington) Memoranda of Observations made In 

 small Aquaria, in which the balance between the animal and vegetable organisms 

 was permanently maintained. These memoranda were read at the Liverpool meeting 

 of the British Association. In memorandum No. 3, we are recommended to be 

 careful to exclude the common polype, or Hydra fusca, from our fresh-water 

 aquaria, particularly when the minnow is kept, as the Hydra, insignificant though 

 they appear, after a short time, cause their death. In No. 3 of the marine 

 memoranda, we have the following form of aquaria (after five years' experience 

 on this subject) recommended by Mr. Warrington : It consists of a four-sided ves- 

 sel, having the back gradually sloping upwards from the bottom, at an angle of 45 

 to 50 degrees, and the consequently extended top sloping slightly downwards, and 

 resting on the upper part of the back ; the bottom, therefore, becomes necessarily
