 Good results may be obtained from pin-hole photography, as will be seen 

 from the frontispiece of this little work. The authors state that a hole i/iooth 

 of an inch in diameter, accurately drilled in a very thin plate, can "be used with 

 perfect success for ordinary out-of-door work, from i-in. focus up to 5-in. focus, 

 over almost any angle, and in studio work for enlarging the same sized hole 

 can be advantageously used from 5-in. focus up to 30-in. focus.

 The diatomist will find this a valuable w^ork of reference. We are sorry to 

 notice there are no illustrations ^
