Dr. E. F. Akmstrong, E.C.S., read a paper entitled "The 

 Bearing of Chemical Eacts on Genetical Constitution," which was 

 communicated by Prof. F. Keeble, Sc.D., F.L.S. The following 

 abstract was furnished by the author : — 



(1) The Eblatiox oe Enzymes to Colour Inheritance in 

 Plants. — The known genetical relation obtaining between the 

 colour-series of Primula sinensis as typified by the colour series : — 



Dominant White — Magenta — Eed — Blue — 

 Eecessive White. 



The universal presence of oxydase in all the members of this 

 series. The demonstration and delineation of oxydase in plant- 

 tissues by means of the benzidine reagent and similar artificial 

 ehromogens. The apparent failure of dominant white flowers to 

 show the oxydase reaction is due to inhibition. The inhibitor 

 may be removed by means of hydrogen cyanide, carbon dioxide, 

 absolute alcohol, and certain other reagents. The presence of 

 oxydase can be then demonstrated. 



(2) The Nature or Oxydases. — The present position of our 

 knowledge based on a review of the work of Bach and Chodat,
