A Happy and Joyous Christmas This year Santa called in to my laboratory at Lund in Sweden while I was visiting there. He confided in me his concern that he may not make it to Australia this year. He feared that with his traditional costume, bearded face, and message of good will to all, he might be arrested under strict new anti-terrorist laws. Or failing that, he might be detained and incarcerated under immigration laws, since he has no visa or passport. Any way he asked me to pass on his wish that you have A Happy and Joyous Christmas and a Prosperous New Year
