[" There is a question . . . that remains unanswered, which is whether 

 any object may become so attenuated that it cannot be made visible by 

 any means. . . . The limit of angle of aperture having been reached — no 

 opportunity remaining of increasing capacity in that direction — is it not 

 reasonable to suppose that with present appliances no greater skill in 

 manufacture can be expected ? "]

[Description of Microscope, ante, p. 554 " We would suggest to Messrs. 

 Watson the advisability of applying a clamp-screw to the tailpieces so 

 that they may be fixed rigidly in the normal position when axial light is 

 being used. We also think it would facilitate the manipulations of the 

 substage and mirror if the pillar support were talkr so as to permit the 

 tailpieces to be longer. At present the tailpieces are so short that there is 

 someditficulty in adjusting the illumination beneath the stage, especially 

 when the Microscope is vertical."]
