A scheme of this kind would funiish opportunity for friendly comparison 

 of work which could not be other than a benefit. A half dozen such 

 laboratories could do the work for the whole country; these could be affili- 

 ated and along this one line at least we should be spared the wastefulness 

 of the anarchy of independent effort. 



COURSE OF STUDY. 



It would immediately come to pass in connection with such labora- 

 tories that courses of instruction would spring up. Such courses would be 

 elected without doubt by many students in the various departments of 

 botany and zoology, and as a result the ability tQ do good work would 

 spread with the demand for it. One year's work in optics with special 

 reference to photomicrography, microscopy and projection, one year in the 

 theory and practice of photography, and two in the theory and practice of 

 photomicrography would fill every requisite, whether of quantity or 

 quality, from the beginning; it would be the work of experience to select 

 finally what is just the best for such a course out of very much that is 

 certainly good. 



I have seen none of the literature of photomicrography of value except 

 Neubatis's "Lehrbuch der Microphotographie." Dr. Neuhaus is a practic- 

 ing physician of Berlin. He has given us a work of such excellence that 

 one does not need to see another; it contains a bibliogi-aphy that probably 

 leaves out little that has been written that is worth keeping. It should 

 be translated into English. It was first published in 1890 and a second 

 edition was called for in 1898. It is the first German work that has 

 survived into a second edition.
