The irrelevant stimulus was named a food sign, and the involuntary motor response of salivary secretion was called a conditioned reflex to differentiate it from the similar response to the biologically adequate stimulus of food, which was termed an unconditioned reflex.

The enterprises they are forced to undertake to meet these charges rest on taxation, a financial basis far stabler than the fitful good intentions of the rich, but apart from this advantage there is little about them to differentiate them from Charities.

Woman, as we saw, in every fiber of her soul and body is a more generic creature than man, nearer to the race, and demands more and more with advancing age an education that is essentially liberal and humanistic. This is progressively hard when the sexes differentiate in the higher grades.

But with living on there, day after day, the acute sojourner became conscious of a new aspect in the spectacle. Without any objective change whatever, variety had taken the place of monotonousness. His host and his host's household, his men and his maids, as they became intimately known to Clare, began to differentiate themselves as in a chemical process.

Hygienic conditions now regarded as essential have displaced many of the older cooking pots which have been condemned as injurious to health. Greater knowledge of the chemistry of cooking, and of the action of acids upon metals, has enabled the scientific cook to differentiate between the pots and pans to use according to the various foods prepared.

It was at first difficult to say what object the Government had in view in endeavouring to compel the Reformers to sign petitions, unless it were the unworthy one of desiring to humiliate men who were already down, or the perhaps more contemptible one of forcing them to turn informers by a process of self-excusing and thus enable them to differentiate in the commutations.
