The structure and polysaccharide constitution of the jelly capsuIe of the egg of R a m pipiens is described. Microscopic examination of the jelly capsule revealed the presence of five discrete jelly layers that differed clearly in their response to selected cytochemical tests. These layers were clas
## Abstract Fertilization of __R. clamitans__ eggs in their native jelly occurred when inseminated with high concentrations of __R. catesbeiana__ sperm. Contrary to previous evidence, the block to crossβfertilization of the __R. clamitans__ Γ __R. catesbeiana__ hybrids may form in nature.
Acute and convalescent sera obtained from 10 adults and 21 children who were infected with influenza B virus were tested by hemagglutination inhibition. Of four antigens used, two tissue-culture-grown antigens were superior to either egggrown or egg-grown, ether-treated antigens in detecting fourfol
