n point, is of a higher order (or involves the equality of a greater number of successive differential coefficients of the ordinates of the curves taken at that point) than that of any other curve of the same kind.

p of a several partial umbels; a leaflet is often supported by a partial petiole. Partial differentials, Partial differential coefficients, Partial differentiation, etc. (of a function of two or more variables), the differentials, differential coefficients, differentiation etc., of the function, upon the hypothesis tha…

asitic or saprophytic fungi, the algal or algalike fungi. The plant body ranges from an undifferentiated mass of protoplasm to a well-developed and much- branched mycelium. Reproduction is mainly sexual, by the formation of conidia or sporangia; but the group shows every form of transition from this method through simp…

an animal or vegetable cell, out of which the various tissues are formed by a process of differentiation; protoplasm.

ion of the rectangular coordinates which determine the position of a point, such that its differential coefficients with respect to the coördinates are equal to the components of the force at the point considered; -- also called potential function, or force function. It is called also Newtonian potential when the force…

The young tissue of a fibrovascular bundle before its component cells have begun to be differentiated. Sachs.

hypothetical homogeneous cosmic material of the original universe, supposed to have been differentiated into what are recognized as distinct chemical elements.

the intensity of heat radiating from a fire, or the cooling influence of bodies. It is a differential thermometer, having one bulb coated with gold or silver leaf. [R.]

rve; hence, the definite integral of the product of any function of one variable into the differential of that variable.

covered by Sir W. R. Hamilton by mathematical reasoning alone, unaided by experiment. -- Differential refraction (Astron.), the change of the apparent place of one object relative to a second object near it, due to refraction; also, the correction required to be made to the observed relative places of the two bodies.…

neral, the group is characterized by the marked development of the sporophyte, with great differentiation of its parts (root, stem, leaves, flowers, etc.); by the extreme reduction of the gametophyte; and by the development of seeds. All the Spermatophyta are heterosporous; fertilization of the egg cell is either throu…

, the generation which bears asexual spores; -- opposed to gametophyte. It is not clearly differentiated in the life cycle of the lower plants. -- Spo`ro*phyt"ic (#), a.

Having a definite organic structure; showing differentiation of parts. The passage from a structureless state to a structured state is itself a vital process. H. Spencer.

not be justified in calling Galileo and Napier blockheads because they never heard of the differential calculus. Macaulay.

s a thallus, which may be filamentous or may consist of plates of cells; it is commonly undifferentiated into stem, leaves, and roots, and shows no distinct tissue systems; the fronds of many algæ, however, are modified to serve many of the functions of the above-named organs. Both asexual and sexual reproduction, ofte…

A portable form of telethermometer, using a telephone in connection with a differential thermometer.

ntrived by Count Rumford which, as modified by Professor Leslie, was afterward called the differential thermometer.

ly, both letters being then used both as vowels and consonants. U and V are now, however, differentiated, U being used only as a vowel or semivowel, and V only as a consonant. The true primary vowel sound of U, in Anglo-Saxon, was the sound which it still retains in most of the languages of Europe, that of long oo, as…

dlass, for bending the bow of an arblast, or crossbow. [Obs.] Shak. Chinese windlass. See Differential windlass, under Differential.

not be justified in calling Galileo and Napier blockheads because they never heard of the differential calculus." Macaulay. (b) In some American colleges, the lowest appointee of the junior year; sometimes, one especially popular in his class, without reference to scholarship. Formerly, it was a custom for classmates t…
