to a ration of separated milk and cotton-seed oil and made an average gain 

 of 52 lbs. per head, at a cost of Kts. 44(1. 



Tlie sheep of the early inhabitants of our mounds, L. Broekema {CuUiira, 

 22 (1910), No. 259, jrp. 136-150).— Bones of sheep found in refuse piles of Hol- 

 land are illustrated and described. Apparently they are identical with the re- 

 mains of Ovis aries pahistris and O. arics studeri found in the Swiss pile works 

 and other deposits of the Neolithic and Bronze ages. 



Beport on pig feeding' experiments, F. Blagrove and B. N. Wale (Jour. 

 Southeast, Ayr. Col. Wye, 190S, No. 17, pp. 25-28). — The object of this experi- 

 ment was to compare rice meal with barley meal for fattening pigs. 



Five pigs of the large black Kent breed 12 weeks of age, previously fed on 

 barley meal soaked in water 12 hours before feeding, were continued on this 

 feed, making an average gain of 18 lbs. per week. In a similar lot, rice meal 

 gradually replaced the barley until the rice became 2\ of the ration, an entire 

 substitution not being made because the pigs would not eat it. The average 

 gain of this lot was 10.5 lbs. per week. The rations were then reversed for 8 

 weeks, and the first lot, which then received the rice, gained 16.25 lbs. per week, 

 and the second lot lost 15.5 lbs. 



Feeding experiments with potato meal and dried potato flakes as supple- 

 mentary feeds for pigs at the dairy institute at Proskau in the summer of 

 1909, J. Klein {Milchiv. Zenthl., 6 {1910), No. 5, pp. 193-199).— In continua- 

 tion of earlier work (E. S. R., 20, p. 7S0), 12 pigs, 6 weeks of age, were divided 

 into 3 groups and fed for 12 weeks on a basal ration of skim milk and ground 

 barley. The first group also received about 0.275 kg. of potato meal per head 

 per day and made an average daily gain of 0.308 kg. per head. Group 2, which 

 received 0.275 kg. of potato flakes, made a corresponding gain of 0.362 kg. 

 Group 3, which received 0.275 kg. of potato flakes inverted with diastasolin, 

 made an average daily gain of 0.374 kg. i)er head. The potato flakes were 

 more economical than potato meal as they cost only about one-half as much. 



Pig feeding experiments with sweet and sour skim milk at the dairy in- 

 stitute at Proskau, 1909, J. Klein (Milchiv. Zenthl., 6 (1910), No. 5, pp. 215- 

 222). — Twelve pigs, 3 months of age, were divided into 2 groups and fed for 12 

 weeks a basal ration of ground barley and potato flakes to which flsh meal was 

 also added the latter half of the period. Group 1 received an average of 5.5 kg. 

 of .sweet milk per head as a supplementary ration and made an average daily 

 gain per head of 0.601 kg. and dressed 81 per cent of the live weight. Group 

 2, which received 5.5 kg. of sour milk per head per day, made a corresi)onding 

 gain of 0.655 kg. and dressed 80.65 per cent. This result agreed with that of 

 previous experiments. 



There seemed to be no advantage in souring the milk as there was a slight 

 loss of sugar, though it was thought that sour milk had a slight diatetic effect 

 which offsets the loss of sugar. There was no noticeable difference in the 

 chemical composition of the flesh. Analyses of the feeds are given. 



The inheritance of coat color in horses, J. Wilson {Sci. Proe. Rnij. Dublm 

 Soc, n. ser., 12 (1910), No. 28, pp. 331-3.'fS).—Tlw author presents data on the 

 relative dominance of coat color in horses, obtained from studbooks. The 

 validity of the conclusions drawn are somewhat affected by the varying notions 

 of horse breeders as to color. 



In the Shires and Clydesdales black and chestnut were recessive to bay and 

 brown, and all four were recessive to gray and roan. In thoroughbreds black 

 was dominant to chestnut and recessive to brown. Brown was probably domi- 

 nant to bay. In all breeds dun was probably dominant to black, brown, bay, 

 and chestnut. The author states that most, of the thoroughbreds recoided in 

 the studbooks as blacks are really browns.
