ABSTRACT
To see if there were a significant relationship between the short form of Dees, O'Reilly, and Griffith embedded figures test and playing ability for tennis as measured by tournament rank order, setting the minimum correlation coefficient at .70, from 116 beginning, 37 advanced, and 72 intercollegiate male and female tennis students from 6 universities data were collected by 9 instructors. Spearman and Kendall rank-order correlations and partial correlation indicated that, even though several values were significant, most were not high enough to conclude that tennis players are field independent.

Makisterone A is the predominant ecdysone in the 96 +/- 4-hour-old embryo of the large milkweed bug and it is the first molting hormone with a C-24 alkyl substituent of the side chain to be isolated and identified from an insect. In addition, unknown compounds that may represent other C28 ecdysones were detected in very low concentrations. The milkweed bug could well possess a biosynthetic-metabolic pathway for C28 molting hormones instead of or in addition to known pathways for the C27 ecdysones.
