Abstract
Fertilized segmenting rabbit ova are capable of surviving aerial transport over long distances. Two different breeds of rabbits have been established from ova fertilized in the United States and flown in vitro to Cambridge University, England. The percentage of transplanted eggs which developed to young was 10 percent in the first experiment, where only 2-cell ova were used, and 30 percent in the second experiment in which all ova developing were shipped in the 4-cell stage. The ova were shipped in small phials (1 ml. capacity) containing whole blood serum, to which a drop of penicillin had been added. These were put in thermos flasks containing small ice balloons and shipped by air and rail. The time interval from recovery of the ova to time of transplantation was 27 to 30 hours.
