ordinary wooden feet be terminated by a truncated cone of glass 

 inverted, or be closely encircled by a zone of the same material 

 several inches broad and having its external surface convex, the 

 desired end, total exemption from annoyance, will be attained. It 

 is scarcely necessary to remark that the bed-furniture must not be 

 in contact with any part of the room, or with the glass feet or zones. 



In hot climates, where noxious animals of various kinds swarm, 

 security during the hours of repose in bed from many species, which, 

 though unable to fly or leap, can walk with facility upon a vertical 

 surface of clean glass, may be effected by placing the feet of beds, 

 guarded in the manner above described, in shallow vessels of any 

 convenient size, shape and material containing finely pulverized 

 chalk, gypsum, flour of wheat, or other dry substances reduced to 

 an almost impalpable powder ; the minute particles by their attach- 

 ment to the climbing apparatus completely preventing its adhesion 

 to the glass. The success of this plan depends upon the substances 

 employed being thoroughly well comminuted and kept free from 

 moisture. 



I may mention, in conclusion, that a scientific friend of mine has 

 recently caused the proposed method of affording security from the 

 bed-bug to be carried into effect, and the parties for whose benefit 

 the experiment was made affirm that it succeeds perfectly. In one 

 instance only it appeared to fail, but the cause was soon detected ; 

 part of the drapery, of the bed was found to be in contact with the 

 floor of the room, and up this the bugs had evidently climbed, for, 

 when the intruders were secured and the drapery was removed, all 

 further attempts of this noisome insect to obtain access to the bed 

 were unavailing. Of course when beds are infested with bugs they 

 must be taken down, and recourse must be had to the most approved 

 means of exterminating the vermin, such as stoving, scouring, wash- 

 ing, &c, before the glass protectors can be applied with advantage. 



Notice of an English locality for Helix revelata, Ferussac. 



Helix revelata was added to the British fauna by Professor Forbes, 

 who discovered it near Doyle's Monument in Guernsey. Specimens 

 from that place and from the adjacent islet of Lihou, the donation 

 of Mr. Lukis, are preserved in the British Museum. In Pfeiffer's 

 Monograph the island of Jersey is stated as a habitat, but without 

 the citation of any authority. In June 1847 I met with this shell 

 under stones on the top of a bank upon the down crowning a cliff 

 near the harbour of Rozel, and looking towards the coast of France. 

 Mr, William Thompson (Ann. and Mag. Nat. Hist. 1840), when 

 comparing the Irish species of land and freshwater mollusca with 

 those of Great Britain, laid some stress on the circumstance that 

 Helix aperta and H. revelata had never been found in Great Britain, 

 but only in the island of Guernsey. I have now the good fortune 

 to announce the interesting fact of the occurrence of the latter shell 

 in England. The discovery is due to my son, Mr. Arthur E. Benson, 

 who on the 16th instant brought in a depilated specimen which he
