In delicate researches two divisions of the scale should always be read, not merely for increased accuracy but to obtain the corrections for " run " from the observations themselves.
One reply to this is that it is not difficult to determine from time to time the errors of the screws and to apply the necessary corrections to the observations.
All this is true, but three readings instead of one for each pointing, much more figure-work in computation (especially if corrections have to be applied to the scale readings to reduce them to exact normal screw readings), are factors which involve a far greater expenditure of time than making a few additional turns of a screw in the process of measurement.
In the case of the original Repsold plan without clockwork the description is not quite exact, because both the process of following the object and correcting the aim are simultaneously performed; whilst, if the clockwork runs uniformly and the friction-disk is set to the proper distance from the apex of the cone, the star will appear almost perfectly at rest, and the observer has only to apply delicate corrections by differential gear - a condition which is exactly analogous to that of training a modern gun-sight upon a fixed object.
The Latin editions of part of these works have been modified by the corrections which the monkish editors confess that they applied.
Goetz, 1895, with the author's corrections and additions); also E.
The other is for more modern additions, corrections and comments made by you and other readers.
Special experiments were made to determine the work done against resistances outside the vessel of water, which amounted to about 006 of the whole, and corrections were made for the loss of heat by radiation, the buoyancy of the air affecting the descending weights, and the energy dissipated when the weights struck the floor with a finite velocity.
Berthollet's theoretical views regarding the composition of the metallic oxides, and he also showed Berthollet's "zoonic acid" to be impure acetic acid (1802); but Berthollet (q.v.), so far from resenting these corrections from a younger man, invited him to become a member of the Societe d'Arcueil.
However, subsequent additions and corrections have detracted much from its value, especially when it became understood that the above sub-orders are by no means natural groups.
From 1879 to 1888 he was engaged on difficult experimental investigations, which began with an inquiry into the corrections required, owing to the great pressures to which the instruments had been subjected, in the readings of the thermometers employed by the "Challenger" expedition for observing deep-sea temperatures, and which were extended to include the compressibility of water, glass and mercury.
Pp. 26 and 159), was followed by a second edition in 1841, in which nearly all the corrections of the reviewer were adopted, and in 1844 began the publication of The Genera of Birds, beautifully illustrated - first by Mitchell and afterwards by Mr Wolf - which will always keep Gray's name in remembrance.
Cuvier seems to have acquiesced in the corrections of his views made by Geoffroy, and attempted no rejoinder; but the attentive and impartial student of the discussion will see that a good deal was really wanting to make the latter's reply effective, though, as events have shown, the former was hasty in the conclusions at which he arrived, having trusted too much to the first appearance of centres of ossification, for, had his observations in regard to other birds been carried on with the same attention to detail as in regard to the fowl, he would certainly have reached some very different results.
It has been found that variations in barometric pressure affect the flash-point and accordingly corrections have to be made in obtaining strictly comparative results at different pressures.
The insular government, however, has created a seventh administrative department - that of health, charities and corrections - and requires that the head of this shall be chosen by the governor from among the five members of the Executive Council who are not heads of the other departments.
The most useful edition is that of Mansi (38 vols., Lucca, 1738-1759), giving Pagi's corrections at the foot of each page.
We get therefore M 2 = MH X M/H = 27r 2 A(d 2 - l 2) 2 tan 0/t 2 d (42) s H 2 =Mhxh/M = 87r 2 Ad/tt 2 (d 2 -1 2) 2 tan B} (43) When a high degree of accuracy is required, the experiments and calculations are less simple, and various corrections are applied.
For specimens of large sectional area it is necessary to apply corrections in respect of the energy dissipated by eddy currents and in heating the secondary circuit.
The actual magnetizing force H is of course less than that due to the coil; the corrections required are effected automatically by the use of a set of demagnetization lines drawn on a sheet of celluloid which is supplied with the instrument.
Assuming the density of Bi to be 9.8, and neglecting corrections for heat dilatation, his value for the susceptibility at 20° C. is equivalent to - 13.23 X 10 -6.
The first maximum in fact occurs when 6=2A-0046X, and the first minimum when 5 = 8X- oo16X, the corrections being readily obtainable from a table of G by substitution of the approximate value of V.
Extensive "corrections" of the river bed, especially the canal of Diepoldsau, have been carried out in the lower bit of this part of the valley, while from a little north of Ragatz the right bank belongs first to Liechtenstein and then to the Austrian province of the Vorarlberg.
Whatever additions it may receive, and whatever corrections it may require, this analysis of social evolution will continue to be regarded as one of the great achievements of human intellect.
A board of state charities and corrections, established in 1869, supervises and controls all of the penal, charitable and correctional institutions of the state at large and also the local almshouses.
In addition to the institutions under the board of charities and corrections there are two under the board of education, and supported wholly or in part by the state, the School for the Deaf (1877) and the Home and School for Dependent and Neglected Children (1885) at Providence.
In that case I correct only such mistakes as I can recall in the few minutes allowed, and make notes of these corrections at the end of my paper.
In rewriting the story, Miss Keller made corrections on separate pages on her braille machine.
Long corrections she wrote out on her typewriter, with catch-words to indicate where they belonged.
She sat running her finger over the braille manuscript, stopping now and then to refer to the braille notes on which she had indicated her corrections, all the time reading aloud to verify the manuscript.
The ability to read the lips helps Miss Keller in getting corrections of her pronunciation from Miss Sullivan and others, just as it was the means of her learning to speak at all, but it is rather an accomplishment than a necessity.
