THIS communication deals with work on the effect of magnetic field on living ascites tumour cells in vitro. The hanging-drop culture was prepared by diluting a 7-day-old transplanted ascites mouse tumour with suitable aliquots of Tyrode solution. The culture slide to be exposed to the field was then placed between the poles of an Alnico permanent magnet in a horizontal position at a constant temperature of 37° C. The field strength used during the experiment was about 4,000 gauss and was determined independently by the susceptibility technique. The control slides not exposed to the field were treated identically. The microscopic examination of the slides was carried out periodically.
