both through cell division and conjugal ion. Author concludes that the nucleus is not the 

 sole bearer of hereditary factors but that on the contrary heritable variations may arise in 

 and be transmitted by the chromatophores and the cytoplasm. — Lcunas L. Burlingame.

 spring wheat, named Kota, has been found to possess resistance to the form or forms of stem 

 rust of wheat present at Fargo, North Dakota, Brookings, South Dakota, and St. Paul, Minne- 

 sota, in 1918. Preliminary tests with Kota show it to have yielding ability. In baking tests 

 it ranked high when compared with other bread wheats.— H. K. Hayes.

 hybrids, secured by crossing Medicago sativa (common alfalfa) with Medicago falcata (yellow- 

 flowered). The hybrids showed 47.5 per cent more weight than the parents. No significant 

 differences were observed in the heights of the hybrid and the non-hybrid plants. Increased 

 weight was then probably due to an increased number of stems per plant. Plants of M. falcata 

 showed less winter-killing than the other groups. — F. M. Schertz.

 spots on tergum of fifth abdominal segment. Selection isolated two types, the two-spot and 

 the six-spot, although the germinal behavior of the three separate strains was distinct. 

 Crosses indicate that (1) the same high factor has been isolated in all three strains; (2) the
