376 EXPERIMENT STATION RECORD. 



over the skull of the horse. A pull from any portion of such a sheet w^ill 

 alter the longitudinal axis of the pins. 



Reasoning from analogy, the author believes that the position of the hair 

 whorl will depend upon the part of the head which has the best development 

 of muscles. A horse with a well developed nervous system will have an active 

 movement of the eye and ear muscles, while large respiratory organs will 

 necessitate a strong musculature about the nose. Therefore, it is argued that 

 a conspicuous facial whorl signifies a highly bred animal with a nervous 

 temperament. The author also ventures to draw other conclusions regarding 

 hair whorls as indications of an animal of superior qualifications. 



A bibliography is appended. 



Who has seen a European wild ox? M. Hilzhkimer (Jahrh. Wiss. u. Prakt. 

 Tierziicht, 5 (1910), pp. 42-93, figs. 17). — A discussion of the characteristics 

 of Bos primigenius, which inhabited Europe within historic times, as described 

 or depicted by different authors and observers both ancient and modern. 



The Augsburg painting of the wild ox is considered to be the best repre- 

 sentation made in the Middle Ages, while the pictures in Herberstain's Travels 

 can not be true to life, although Herberstain's account of B. primigenius is 

 an important document in furnishing evidence that the species in the wild 

 form lived in the sixteenth century. The author finds no substantial evidence 

 that any wild form of B. longifrons lived in eastern Europe. 



A bibliography is appended. 



Morphological-microscopical study of sheep's wool as a help in judging 

 the purity of the breed of sheep, B. Macalik {Jnhrl). Wiss. u. Prakt. Tierzucht, 

 5 {1910), pp. 141-153, figs. 12). — This article contains discussions, measure- 

 ments, and micro-photographs of wool hairs, of pure-bred sheep of the Balkan 

 States and crosses of these with the Rambouillet and Merino breeds. The 

 value of using the microscope in studying the strength of the wool fiber and 

 in classifying wool and related problems is pointed out. 



Growth measurements of horses, F. Schottler (Jahrb. Wiss. u. Prakt. 

 Tierzucht, 5 {1910), pp. 1-^1) ■ — Measurements were made of different lots 

 of horses in the Province of Hanover, those of one lot of 48 horses being as 

 follows : At 6 months of age, cii'cumfereuce of cannon bone 15.75 cm., height 

 of withers 131.04 cm., girth 135.S1 cm. ; at 1 year of age, circumference of 

 cannon bone 10.73 cm., height at withers 139.83 cm., girth 14G.83 cm. ; at 1* 

 years of age, circumference of cannon bone 23.81 cm., height at withers 147.58 

 cm., girth 167.1 cm. 



The author found that the cannon bone on the right foreleg was generally 

 larger than that on the left. Several other conclusions are also drawn, and a 

 bibliography on the subject is appended. 



Lord Morton's quagga hybrid and origin of dun horses, J. Wilson {Nature 

 [Lundon], 84 {1910), No. 2133, p. 328; Vet. Rcc, 23 {1910), No. 1159, pp. 189, 

 190). — Because the author thinks that a chestnut mare could not produce a 

 bay offspring, he has some doubts about the ancestry of the famous quagga 

 hybrid of liOrd Morton. It is further stated that the dun color in horses 

 is not a reversion. 



[Lord Morton's quagga hybrid and origin of dun horses], J. C. Ewart 

 {Nature [London], 84 {1910), No. 2133, p. 328; Vet. Bee, 23 {1910), No. 1159, 

 pp. 189, 190). — This is an answer to the objections raised by Wilson in the 

 article noted above. 



It is pointed out that the prevailing color of all the wild Equidfe now living 

 in Asia is dun. Crosses between varieties of Burchell's zebras with white 

 points and crosses between zebras and ponies have usually dark patches at 

 the fetlocks, and the body color of zebra-horse hybrids is usually yellow.
