By E. J. E. Creese, F.R.M.S. 



SOME time ago, a few creditably-mounted Microscopical Slides 

 of Wood Sections were submitted to me for inspection, with 

 an apology for their having been ^' finished " under unfavourable 

 circumstances. These were — that the mounter (a member of the 

 local Microscopical Society with which I am connected) having 

 lived in a village, had there to construct and find his mounting 

 apparatus, and did not possess a turn-table. 



This suggested to me the feasibility of constructing a " home- 

 made " turn-table, which anyone with ordinary knack can make 

 for himself at the cost of a shilling, and of which I will give a 

 brief description. 



The materials are easily obtained, and it will be found to w^ork 

 very satisfactorily. A, B, C (Fig. i) are three pieces of hard 

 wood, cut out and put together to the pattern shown. The length 

 of A and C is 9 inches, and the height of B is regulated by the 

 length of the arbor, E. D is an old, heavy clock-wheel of nearly 

 3 inches diameter, which may be obtained of any clock maker 

 for a few pence, or at a gift, inclusive of rust, dust, and cobwebs. 

 This wheel is always supplied with an arbor, E, attached, which 

 measures 2 to 3 inches in length. F is a little grooved wheel.
