 purpose, while a half-inch more room would be very 

 desirable. The object of all this is to get room enough, 

 so that we can employ a circular stage large enough to 

 work an object-carrier. 



. Next, see that there are no sub-stage fittings, which, 

 by their particular method of attachment, will inter-

 to a considerable extent, been copied by his friends. 

 Any watchmaker or machinist can do the work in
