NOVELTIES. 



Moginie's Collecting Case. — A new form of collecting case 

 has been recently brought before the Club by Mr. Moginie, of 35j 

 Queen Square. It is intended to accompany his well-known col- 

 lecting stick and apparatus, introduced some time since. It is 

 made of stiff leather, lined with baize, and contains three strong 

 bottles (" York " j)attern) of the size best adapted for use with the- 

 collecting stick, and four smaller bottles. There is also a screwed 

 ring for attaching each of the larger bottles to the stick, a space for 

 the steel cutting hook for gathering aquatic plants, and a small 

 magnifying lens, mounted in horn. The case is made to open like 

 a portmanteau, so that each bottle is easily got at, and no space 

 wasted. The whole is very portable, and is easily carried by means 

 of a strap over the shoulder. The article can be supplied for twelve 

 shillings, or, with the collecting stick, &c., for one guinea. 



Porcelain Lamp Shade. — This has been introduced by Mr. 

 Hailes, and consists of a short cylinder of unglazed earthenware, 

 blackened on the outside, and for a short distance from the top, 

 inside. It is of sufficient size to drop easily over the chimney of 

 the lamp, and rests upon a gallery attached to the burner, or is held 

 by a projecting arm from the stem of the lamp stand. There is a 

 portion of the lower part cut away on one side, large enough to allow 

 the light to pass in the required direction. Its small size renders it 

 very convenient for travelling lamps, and the material being white 

 the interior forms a very efficient " white cloud " reflector. We 

 believe that the cost will be very small. 



Plate for Shewing Compression and Flexure of Glass. — 

 Those who have studied the phenomena of i)olarized light are ac- 

 quainted with the remarkable de-polarizing effect produced by glass 

 in a state of imequal tension. This is often effected by rapidly 

 cooling pieces of glass of various forms, which, when examined by 

 polarized light, exhibit the effect produced by varying shades of 

 colour of more or less intensity. But the effect may be shewn, and 

 the cause demonstrated by arranging a piece of glass in such a manner 

 as to render it possible to apply pressure, and so bring the particles 

 of the glass into a condition of unequal tension, while under ob- 

 servation. Mr. Bailey, of Fenchurch Street, has reduced the size
