THE MICROSCOPE 251 
be an elaborate and expensive instrument. Buy 
at first a good stand, furnished, perhaps, with one 
eyepiece and one objective; add other eyepieces, 
objectives, and accessories as you need them or 
can afford them. High magnification is sometimes 
necessary, but I can assure you that most Nature- 
work is done with low powers. 
{ have just been doing a little work with two 
microscopes made by Messrs. R. and J. Beck, Ltd., 
68, Cornhill, London. One of them is called the 
** Star,’’ and I am sure no better or cheaper instru- 
ment could be made for the use of beginners ; 
indeed, I know a number of advanced workers who 
make use of it, and speak highly in its praise. The 
cost of a “Star” stand with one eyepiece and 
one l-inch object-glass is about £3; with an extra 
eyepiece and a +-inch objective in addition the 
cost is £4 6s. The other microscope is the ‘‘ London,’’ 
a real beauty, finished with the greatest nicety, and 
delightful to handle. But it is more costly than 
the “ Star.” The stand alone, in a mahogany case, 
costs £3 5s. 6d.; with the addition of an eyepiece 
and two object-glasses, the bill amounts to a little 
over £5. This outfit gives a range of magnification 
from 50 to 270 diameters. 
I mention these excellent microscopes to give you 
an idea as to what price you must pay for an instru- 
ment by a reliable maker. There are a number of 
firms whose work can be depended upon; I have 
cited Messrs. Beck because I have worked with 
several of their instruments, and know their points. 
When you possess both camera and microscope, 
you will be able to use the two in conjunction, and
