differential coefficient

The efforts are proceeding slowly and tentatively because the price differential of the fuel is only one factor to consider.

A record is generally kept of the number of nucleated red cells seen during a differential count of leukocytes.

The differential count is best made upon a film stained with Wright's, Jenner's, or Ehrlich's stain.

Jenner's stain, which gives a somewhat similar picture, is preferred by many for differential counting of leukocytes.

The principal source of the irregularities was found in the concealed upper differential wheel of the Grubb slow motion.

You,” said I. “You drive a nail as if it were an abstruse problem in differential calculus.
