Contribution to the knowledge of a beet-leaf ration on the composition of 

 milk fat, M. Fritzsche {Ztschr. UntcrsucJi. Nahr. u. GenusstntL, 17 (1909), 

 No. 9, pp. 533-536; abs. in MiUhw. Zenthh, 6 (1910), No. 8, pp. 382, 383).— 

 Aiiiilyses were made of butter from the milk of cows fed u ration containing 

 fresh beet tips and beet leaves. The results were similar to those obtained by 

 Siegfeld, noted above. 



The insoluble barium number (Ave-Lallemaut's method) was unaffected, but 

 the soluble barium value was raised from 10 to 20 units, as is the case when 

 coconut fat is added to butter. The Hanus-Stecklester value, on the contrary, 

 was unaffected by feeding beet leaves. Hence, by means of these 2 tests butter 

 adulterated with coconut fat can be distinguished from pure butter made from 

 milk of cows fed a ration containing beets or beet leaves. 



[A nonsuction milking machinel, .J. H. Monrad (Hoard's Dairyman, Jfl 

 (1910). \o. 32, p. 935, figs. 3). — A brief description of an improved form of 

 Nielson's milking machine, which consists of 2 sets of curved aluminum plates 

 covered with a removable rubber sheet on the side toward the teats. The 

 plates are mounted in an iron frame and are set in motion by 2 flexible shafts 

 so that the plates are moved against each other in such a manner as to press 

 the teats first above and then gradually downward. The plates may be regu- 

 lated even while in motion to suit various sized teats. The frame of the plates 

 is hung in a box, from which a tube conducts the milk into tbe pail hung far- 

 ther forward on the cow. The whole weight is fx'om 44 to 5* lbs. The flexible 

 shafts are connected with a fixed sbaft above the stalls carrying suitable eccen- 

 trics, whereby the desired motion is obtained. The fixed shaft may be turned 

 by hand or power. The flexible shafts are easily removed from stall to stall by 

 a handle with a spring catch. The machine may also be used in the fields. 



" The machine is plain and simple in construction, easily taken apart and 

 cleaned and reserve parts reiilaced and may be repaired by any handy black- 

 smith ; the plant should not be expensive and hence this machine should be 

 available for the small herds." 



A milk preserving machine (Jour. Bd. Agr. [London], 17 (1910), Xo. 5. p. 

 412). — A brief note on a French patent of a machine for preserving milk by 

 subjecting it to a high pressure and then pasteurizing. 



Report upon an epidemic of scarlet fever in London and Surrey due to an 

 infected milk supply in June, 1909, W. H. Hamer and T. II. Jones (Abs. in 

 Jour. Compar. Path, and Titer., 22 (1909), No. 4, pp. 363-377, fig. i).— The out- 

 break of scarlet fever was traced to a single farm, and in the opinion of the 

 authors the infection was not from a human source but from cows which had 

 eaten infected cake. 



Milk-borne scarlet fever (.Jour. Compar. Path, and Ther., 22 (1909), No. 4, 

 pp. 340-3 f/S). — A criticism of the report noted above. "The explanation put 

 forward in the report recjuires i)revious assent to several things which are not 

 only unproved but highly improbable. Most of these improbabilities have al- 

 ready been noticed, but the greatest of them is that the disease of human beings 

 which is termed scarlet fever is couuuunicable to cows, and is manifested liy 

 an eruption on the udder and teats." 



Bibby's book on milk (Liverpool, 1910, seet. 2, pp. 37-96). — A resume of the 

 English milk law, with quotations of some typical and imiwrtant cases where 

 dealers were prosecuted for selling adulterated milk. Subjoined to the above 

 are abstracts of the milk investigations, which have been previously noted 

 from other sources. 



Some creamery problems and tests, L. M. Davis (California Sta. Circ. 54,
