Effect of partial starvation followed by a return to normal diet, on the 

 growth of the body and central nervous system of albino rats, S. Hatai 

 (Anicr. Jour. Physiol., IS (1907), No. 3, pp. 309-320, fig. 7).— In so far as the 

 weight of the body and central nervous system are concerned the author con- 

 cludes from the investigations reported that the effect of a 3 weeivs' period of 

 partial starvation on albino rats 30 days old is eventually completely com- 

 pensated. " The riiemical compof^ition of the brain and spinal cord is, how- 

 ever, not entirely free from the effect, as is indicated by the higher percentage 

 of water, and lower percentage of ether-alcohol extracts, in the experimental 

 rats as compared with the controls." 



Denatured sugar in the fattening of farm animals, II. Legras (Betleracc, 

 11 (1907), No. Jf2o, pp. 169, 170). — Draft oxen fed denatured sugar as part of 

 the ration in a 45-day test made an average daily gain of 1.516 kg. per head 

 per day as compared with 1.352 kg. in the case of steers fed a linseed-cake 

 ratiou without tbe sugar. 



Fattening cattle on pasture, M. Kasquin (Jour. Soc. Agr. Brahant ct Hai- 

 )iaut. 52 (1907). Xo. IS, pp. 505-508). — A summary of data on the possibilities of 

 fattening of cattle on pasture. 



The use of skim milk in the fattening of calves, Malpeaux (Jour. Soc. 

 Agr. Brahant ct Haiiiaut, 52 (1907). Xo. 16. pp. Ji59-Ji61). — A summary of 

 recent data on the importance of skim milk in calf feeding when rightly used. 

 Among other topics the hygienic value of the lactic acid of sour milk is 

 considered. 



■ Leaves as a sheep feed, H. Isaachsen (Bcr. Xorgcs Laiidhr. Iloiskoles 

 Virks., 1905-6, pp. 216-220). — According to the author's analyses aspen leaves 

 had tbe following percentage compusition : \Yater 9.06, total protein 13.13, 

 amids 0.80. fat 5.64, nitrogen-free extract 45.95, crude fiber 18.52, and ash 7.70 

 per cent. The p.n-centage composition of birch leaves was water 9.03, total 

 protein 12.22, amids 0.69, fat 9.05, nitrogen-free, extract 48.20, crude fiber 17.21, 

 and ash 4.29 per cent. Of the total protein of the aspen leaves 12.33 per cent 

 was true protein and 7.32 per cent digestible protein. Similar A'alues in the 

 case of tbe birch leaves were 11. .53 and 5.42 per cent. According to tbe author, 

 1 to 1.2 kg. of mixed poplar and birch leaves is equal for sheep feeding to 1 kg. 

 of good meadow hay. — f. w. woll. 



Sheep on paspalum grass, A. H. Haywood (Agr. Gaz. X. 8. Waies, IS (1907), 

 Xo. 3. p. 23 Jf). — In a brief uote on Romney sheep at the Wollongbar Experi- 

 ment Farm, it is stated that very satisfactory results have been obtained. 

 The sheep mature early and produce a good fleece, the average weight being 

 about 7 lbs. of wool. The carryiug capacity of paspalum grass, " at a very low 

 estimate, may be put at 10 sheep to the acre. Farmers in the district who 

 have tried this bret-d speak very higbly of tbem." 



An experiment in feeding pigs, E. Voglino (Coltiratorc, 53 (1907), Xo. 

 15. pp. .'i56. Ji'j7). — A Itrief note on gains made by two sows fed a mixed ration. 



Different quantities of skim milk for pigs fed the same feeding stuffs, 

 Klein (Milchw. Zcnthl., 3 (1907), Xo. J,, pp. 137-lJ,9).—ln 21 weeks the greatest 

 gain, 0.611 kg. per head per day, was made by the pigs receiving the greatest 

 quantity of skim milk, and the smallest gain, 0.582 kg. per head per day, was 

 made on the smallest skim milk ration. A lot fed fish meal in addition to 

 skim milk and grain gained 0.608 kg. per head per day. 



Feeding experiments with dried potatoes, Gaul (Deut. Landiv. Presse, 3't 

 (1907), Xo. J/O, p. 325). — From a feeding experiment with pigs, which is 

 briefly reported, tbe conclusion is drawn that under local conditions dried
