This case report details the clini cal manifestation and course ofglandular tularemia, an uncomm on but significant cause of cervical lymphadenopathy in children. We discuss the uniqu e attributes of this disease along with appropriate steps that lead to early identification of the organism and effective treatm ent. The potential use ofthe organism as a bioterrorism agent is another interesting aspect of this entity.

A program is presented which permits use of a pocket-size programmable calculator, the HP-65, to tally phenotypes resulting from a three-point cross. For practical purposes the total number recorded for any of the eight possibel phenotypic combinations is unlimited. Although programmed operation of the calculator for tallying purposes is slower than a single purpose instrument designed for tallying, this deficiency is componensated by the computational capability of this instrument.
