shown varnished. The coil is now, after being oven-dried, ready 

 for assembling in place on the armature. 



Fig. 318 shows a miscellaneous group of strip- and wire-wound 

 coils. There are three complete lap-coils with radial loops at the 

 ends. On the extreme right is a smaller coil with an oblique loop
