PHOTO-MICROGRAPHY 



Messrs. Watson and Son, being shown in Fig. 25. The block explains itself. It will 

 be seen that the microscope is used with a mirror, and it will be further understood 

 after a little consideration that an objection which holds good to all makes of upright 

 apparatus is especially noticeable in this arrangement — viz., that there is but little 

 possibility for the use of extended camera lengths. To this we shall draw attention in 

 a future article, when describing how to use the apparatus. 



Quite recently the firm of Zeiss have brought forward a somewhat new design, 

 which is capable of being used vertically, at an angle of 45° to the vertical, and 

 horizontally, which for many purposes promises to be of great service. We have 

 critically examined it, and can vouch for the excellency of the details and general 

 arrangement. In calling this stand new, we must admit that some other foreign 

 firms, as well as some English ones, have sold much the same design before ; but we 

 think perhaps not in such a solid and useful form, neither have the details been at all 

 similar. It should be seen to be appreciated. It is shown in Figs. 26 and 27, where 

 it is exhibited in the vertical and other positions. We may mention that the camera 

 is very large and of foreign dimensions, which would be troublesome to English 

 workers because of either having to employ foreign-sized plates or a plate-holder, 

 neither of which are to be recommended. No doubt the firm could alter this on 

 demand.
