American microscopes, and having had the advice of several 
of the most eminent American microscopists, in regard to im- 
provements in the me- 
chanical arrangement 
of our instruments, 
we have devised and 
adopted a variety of 
forms and sizes of mi- 
croscope stands, adapt- 
ed to the use of every 
class of observers, and 
suited to the means of 
purchasers. 
For steadiness of sup-

confident that our mi- 
croscopes will prove 
satisfactory to all who 
may use them.

uprights by a trunnion joint, it allows the instrument to be in-

and steadily in a firm, but elastic brass cylinder, attached to 
the japanned limb, by which means it is readily adjusted to 
any desired focus. The stage is two by three inches, having 
spring clips to retain the object in place when the microscope
