Dear Dr. Lederberg:
We would like to perform some experiments in bacterial recombination as a laboratory exercise in our Microbial Genetics course. We would greatly appreciate your sending us two strains of bacteria which you think would be appropriate for our needs.
Thank you for your kind consideration.
Sincerely,
Herb Ennis
