8o The Nature- Study Exhibition 



arrangement of the latter, and of the series of insects on 

 natural flowers and leaves carefully preserved in natural 

 colours, were such as would prove exceedingly valuable and 

 attractive to the many children who attend the demonstra- 

 tion lessons provided in the museum, and who have little 

 or no opportunities for coming into more direct contact 

 with nature. 



From Cardiff museum came some models intended "to 

 illustrate the salient points of stratigraphical geology". Of 

 these it is said that — 



" The strata being represented by distinctive layers of wood, the ex- 

 posed outcrops must be absohitely correct, whereas in the painted blocks 

 this is not self-evident, being dependent upon the correctness of the 

 artist." 



Mr. G. Herbert Morrell, M.P., exhibited a contour map 

 made by cutting up the sheets issued by the Ordnance 

 Survey, and mounting the pieces so as to bring them 

 to their proper elevations, as indicated on them. 



Mr. George Abbott, of Tunbridge Wells, sent a remark- 

 able series of photographs, showing how the appearance of 

 local rock formations may be recorded. He further illus- 

 trated an inexpensive method of preserving, for ready refer- 

 ence, the specimens illustrating the various rock-beds met 

 with in the neighbourhood of a school and collected by 

 the pupils. 



The life-histories of insects reared, preserved, and mounted 

 by the boys of the Goodrich Field Club (of the Goodrich 

 Higher Grade School, East Dulwich) deserve mention, and 

 the interest taken by the boys in such work is shown by the 

 following description of a complete set of home-made ento- 

 mological apparatus, suitable to the wants of a young col- 

 lector, and which can be easily and cheaply made under the 

 guidance of the teacher. The set comprises : — 



** The net, collecting-boxes, relaxing-lx>x, cyanide or killing bottle 

 (this alone made by teacher), setting and drying cases filled with boards
