Commemoration of the 250th anniversary of the birthday of Linnaeus. In many places academies and societies commemorated this event. In Sweden, Uppsala University, it took place just before the End of Term ceremonies of the University and a number of botanical and zoological taxonomists were invited to a Symposium ”Systematics of To-day”, to excursions in the vicinity of Uppsala, and to the imposing End of Term ceremonies, attended by His Majesty, The King. On that occasion several famous taxonomists received an honorary doctorate from the University. The festivities were concluded by a dinner and ball in the magnificent Rikssaal of the Uppsala Castle. For those who, like myself, had the privilege to attend and enjoy the abundant hospitality and friendliness in this beautiful country, these spring days will forever linger in the memory as delightful from all points of view. To observe flowers along the same trail the Prince of Botanists took with his students centuries ago, to visit Hammarby under delightful weather conditions, gave a peculiar charm to these days; we feel immensely indebted to our hosts, male and female, all gentle, eager, courteous, dignified, and above all, kind.
