Page 47 - In the comparison of two statistical results, the difference between the two results compared to its probable error is of great value. In general, we may take the probable error in a difference to be the square root of the sum of the squares of the probable errors of the two results. If the difference does not exceed two or three times the probable error thus obtained, the difference may reasonably be attributed to random sampling. If the difference between the two results is as much as five to ten...
Page 484 - In every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional to the length of time it has been so used; while the permanent disuse of any organ imperceptibly weakens and deteriorates it, and progressively diminishes its functional capacity, until it finally disappears.
Page 567 - Their colour is bay, marked more or less like the quagga in a darker tint. Both are distinguished by the dark line along the ridge of the back, the dark stripes across the fore-hand, and the dark bars across the back part of the legs.

Page 54 - If r is more than six times the size of the probable error, the existence of correlation is a practical certainty.
Page 567 - That of the colt is long, but so stiff as to arch upward and to hang clear of the sides of the neck, in which circumstance it resembles that of the hybrid. This is the more remarkable, as the manes of the Arabian breed hang lank, and closer to the neck than those of most others.
Page 567 - They have the character of the Arabian breed as decidedly as can be expected, where fifteen-sixteenths of the blood are Arabian ; and they are fine specimens of that breed ; but both in their colour and in the hair of their manes, they have a striking resemblance to the quagga.
Page 567 - ... forehand of the colt are confined to the withers, and to the part of the neck next to them; those on the filly cover nearly the whole of the neck, and the back as far as the flanks. The colour of her coat on the neck adjoining to the mane is pale and approaching to dun, rendering the stripes there more conspicuous than those on the colt. The same pale tint appears in a less degree on the rump ; and in this circumstance of the dun tint also she resembles the quagga.
Page 567 - OUSELEY'S stud groom alleged that it never was otherwise. That of the colt is long, but so stiff as to arch upwards, and to hang clear of the sides of the neck ; in which circumstance it resembles that of the hybrid.
