These slides are shown in fig.
The slides are accurately fitted so as to have no sensible lateral shake, but yet so as to move easily in the direction of the greatest length of the micrometer box.
The later English artists have somewhat changed the mode of communicating motion to the slides, by attaching the screws pdrmanently to the micrometer head and tapping each micrometer screw into its slide.
In this micrometer the three slides moved by S, s, and s' are simple dovetails.
The lowest of these slides reposes upon a foundation-plate pp, into one end of which the screw s is tapped.
I, 2 and 3), used to bolt the head of one of the screws, and the instrument was provided with a slipping piece, giving motion to the micrometer by screws acting on two slides, one in right ascension, the other in declination, so that " either of the, webs can be placed upon either component of a double star with ease and certainty (Mem.
17), which actuate the movable slides, have heads divided into 100 parts, one revolution = 0.5 mm.; so that ten revolutions are = 5 mm., or = the interval between two adjacent reseau-lines, or = the interval between the sides of the " fixed square."
All the essential parts of the micrometer, including the slides, micrometer box, tube, &c., are of steel or cast-iron, so that changes of temperature do not affect the adjustments.
To fulfil condition (I) the plates A i and A, are mounted in circular slides, whose centres are El and E2 respectively, so that by means of the screws Dl, D2, with their corresponding opposing springs F 1 and F 2, the operation can be very easily accomplished.
Owing to their want of adhesiveness, they are, however, usually mounted on glass as microscopic slides, either in glycerin jelly, Canada balsam or some other suitable medium.
Scale-mosses are mounted in the same way, or may be floated out in water like sea-weeds, and dried in white blotting paper under strong pressure before gumming on paper, but are best mounted as microscopic slides, care being taken to show the stipules.
