632 SUMMARY OF CUREENT RESEARCHES RELATING TO 



Through the centre of both tables I bored another hole. Then 1 took 

 a steel saw-plate into which the teeth had not been cut. I had a hole 

 bored in its centre, and two brass handles or pins put in opposite each 

 other near the circumference. This plate is fastened by a pin with nuts 

 on the table over the three castors. The table is perfect. I painted the 

 steel plate. The drawer of the first table on the side serves for accessories. 

 The whole thing cost less than five dollars. The finished table looks aa 

 though made for this purpose, and not for a sewing-machine."]
