If you have any reprints for distribution of your article "Cell genetics and hereditary symbiosis" in Physiol. Rev.
32: 403-430, I would be pleased if you would send me one. I am studying symbiosis in cockroaches and having acquired aposymbiotic
insects I am now trying to devise a method for "re infecting" the insects with their intracellular symbiotes. Your
article is quite thought-provoking. Thank you.
