—Mr. A. M. Edwards read a paper entitled ‘Note on the relations of 
Monochrouiatic Light to Microscopical Observations,” calling atten- 
tion again to the fact of his ha aving some time back brought before 
this Society a theory of his, of the relation of active noiet to 
vision, and the definition of objects seen through lenses; at the s 
time detailing some recent investigations made by others, whic 
considered to confirm his theo pool zn then proceeded to illustrate his 
subject by using the colored plates in Chevereul’s book on the appli- 
cations of colors to the m arts, illuminating them by the So- 
dium flame, gas-light, and the light of burning magnesium succes- 
sively. He remarked how careful observers should be in drawing 
conclusions from what they think they see by means of the micros- 
cope. 
Mr. J. E. Gavit detailed two cases in which he had been called upon 
touse the microscope for the purpose of deciding points in which large 
Sums of money were involved. The first was to decide which of two 
Writings crossing each other —one in black ink, the other in red— was

thought he had seen the formation of an Amoeba from the contents of 
a Pinnularia, and the after formation of an Actinophrys from 
Ameeba.
