The opportunities for carrying out such observational work vary so much in different schools that it is impossible to give specific instructions, which shall be available in all cases.

Toward the end of October, a strange, and, forobservational purposes, a distressing phenomenon took place.
Such an attitude, and the fact that he had taken up observational astronomy in middle life, unconnected with any other scientific institution, tended to make many professional astronomers look upon him askance.
Such an affirmation can not warrantably attach itself to a theory of descent, as it can not be tested by observational methods, but altogether by reference to the laws of thought determining the value of rationalizing processes.
The one view is that observational science can make no account of miracle: the other is that thought concerning a supernatural Being really involved the conception of miracle.
Creation, for example, can not come within the compass of observational science; but creation may nevertheless be a rational conception in dealing with a purely rational problem, which does not at all belong to physical science.
In the last quarter of the 19th century spectroscopy and photography together worked a revolution in observational astronomy, and in both branches Huggins acted as pioneer.

Our observational 'present' is what I call a 'duration.
The analysis of the general character of observed nature set forth above affords explanations of various fundamental observational facts: (α) It explains the differentiation of the one quality of extension into time and space.
Our 'percipient event' is that event included in our observational present which we distinguish as being in some peculiar way our standpoint for perception.
The theory, so far from founding science on a sound observational basis, forces everything to conform to a mere mathematical preference for certain simple formulae.
Nothing, perhaps, tends more to the effective progress of any branch of observational and inductive science, than that we should endeavour to discern clearly the scope and boundary of our subject.
The observational data at his disposal would now be called rude, but they disclosed to the scrutiny of his acute understanding the germ of truth that was in them.
The fact is that direct observational evidence is, from the nature of the processes involved, almost impossible to produce in either case.
But one might fairly ask him what body of direct observational evidence he has of natural selection.
DD] If Mr. Wallace requires direct observational evidence of this kind, I do not suppose he is likely to get any large body of it.
And perhaps it is scarcely too much to say that, at present, we have not observational grounds on which to base a reliable estimate in a single instance.
The observational method applied to consciousness gives us the science of psychology.
Cousin was observational and generalizing rather than analytic and discriminating.
The phase angle, however, varies so much as to suggest that the term mainly represents local causes or observational uncertainties.
The invention of the portable electrometer and the water-dropping electrograph by Lord Kelvin in the middle of the 19th century, and the greater definiteness thus introduced intoobservational results, were notable events.
Thus the differences in the wave-lengths of presumably the same lines as measured by different Arctic observers may be only partly due to unfavourable observational conditions.
In the southern hemisphere there is comparatively little inhabited land in high latitudes and observational data are few; thus little is known as to how the frequency varies with latitude and longitude.
Whilst no small amount of observationalwork has been done in these new branches of atmospheric electricity, the science has still not developed to a considerable extent beyond preliminary stages.
Before considering observational data, it is expedient to mention various sources of uncertainty.
Owing to observational difficulties, the exact measure of success attained is a little difficult to gauge, but it seems fairly certain that raindrops usually carry a charge.
Nor was activity confined to the observationalside of the science.
His work was not mainly in the field of observational astronomy, and therefore did not materially influence that branch of science.
It has been assumed to have the velocity of light only because that hypothesis does not conflict with observational data.
In a few years commenced the epoch-making work of Campbell, in the most refined and difficult problem of observational astronomy,--that of the measurement of the motion of stars to or from us.
Taking up the question on the observational side, a source of difficulty and confusion at once presented itself.
As Hansen was Germany's greatest master in mathematical astronomy, so was the venerable Argelander in the observational side of the science.
I suspect that the apparent anticipation is simply an observational illusion, similar to the illusion of time-reversal experienced when it was first observed, though not realized, that positrons sometimes exceeded light-speed.
I did not realize that you would wish additional observational data before the swing began.
Both of the astronomers were heartily sick of spending so much of their observational time with recalcitrant equipment; and in making observations of the globe from which they had come.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "observational" in a variety of sentences. We hope that you will now be able to make sentences using this word.
