 Title    Composition of Propolis in Oxfordshire, U.K. and its Relation to Poplar Bud Exudate  
 Abstract    Propolis balsam from four locations in Oxfordshire was analysed. The balsam was qualitatively similar but showed large quantitative differences in composition. These quan-titative differences are related to the bud exudate composi-tion of the poplars from which balsam was gathered.

 Title    Response Characteristics and Identification of Extrinsic Mushroom Body Neurons of the Bee  
 Abstract    The activity o f single neurons with constant discharge frequencies in the area around the a-lobe o f the mushroom bodies o f the bee was recorded intracellularly. The spontaneous discharge fre­ quency o f these neurons ranged between 5 and 95 im pulses per second. W hen stimulated, about 80 percent o f the neurons responded to at least one o f five different sensory modalities: scent; light; air current to the antennae; sugar water applied to the antennae and to the proboscis. 45 percent o f the neurons responded to two or more m odalities, these multimodal neurons are com ­ mon in the median protocerebrum o f the bee. The differentiated response pattern o f the cells does not allow a simple classification. Som e o f the neurons were identified after the injection o f the flu­ orescent dye Procion yellow. W e found 4 neurons with arborizations in the a-lobe and the calyces o f the mushroom bodies.

 Title    Navigation and Compass Orientation by Insects According to the Polarization Pattern of the Sky  
 Abstract    A recent theory attempts to explain how bees take their compass orientation from the pattern of polarized light in the sky (S. Rossel and R. Wehner, Nature 323, 128-131 (1986)). According to this theory, orientation can be erroneous and lead to the wrong course of a recruited bee in search of the foraging site whenever only a small patch of the blue sky is visible to the bee. It is shown that orientation under natural conditions is not erroneous, if the compass reference is variable in time but equally defined for both, scout bees and recruits.
