Lens,” and will be published quarterly. This number reproduces a paper 
and plate of Mr. Johnson’s from the “ Monthly Microscopical Journal,” but 
it has other non-illustrated papers which are very good indeed. We wish 
“The Lens ” every success, and we feel certain it deserves a hearty welcome 
from microscopical readers.
