in successive generations. No explnnation of these pbenon.cnn 

 was put forward, as further experiments were still in pi'ogress. 



In dealing with the purely Mendelian aspect of the results 

 the following points were clearly brought forward : — (1) Silver is 

 dilute Blue, (2) Blue is dominant to Silver. (3) Chequering 

 and Grizzling are both dominant to absence of pattern. (4) Griz- 

 zling is dominant to Chequering. (5) A Mealy is a Grizzled bird 

 with the White replaced entirely or partially by Red. (6) Red in 

 a Mealy is dominant to White, hence a Mealy is dominant to a 

 Grizzle. (7) White and Grizzling combine to have a common 

 inheritance. (8) Red combines with Grizzling in the same way 

 as White. 



Dr. G. Stewardson Brady, M.D., F.R.S., C.M.Z.S., presented 

 a paper on Marine Ostracoda from Madeira, based on specimens 

 collected by the Rev. Canon Norman, F.R.S., in the spring of 

 1897. Apart from the species described as new to science, the 

 collection was interesting as extending the known range of sevei-al 

 species from the European and North Atlantic areas much farther 

 southward, though not quite into the tropical zone.
