A NOVEL feature in the Newark Agricultural Show, recently held, of which Colonel Fane, of Fulbeck, was President, and Thomas Earp, Esq., M.P., was HOR. Secretary, consisted of a special prize, given by the Bight Hon. Viscountess Ossington, ‘‘ €or the best milking cow, judged for the quality and breed of the animal, and the quality and quantity of the milk produced,” the special conditions being that all animals exhibited in that class should be milked on the show ground on the evening of the first day, and that the milking for the competition should take place on the second day of the show, at a time to be fixed by the Committee. Quantity in gallons of Milk yielded, 1.578 1.344 There were five entries, three putting in an appearance.The following is the report of Mr. Alfred Ashby, of Grantham, who andysed the milk on behalf of the Committee, and it is satisfactory to note that precisely the same order of merit was assigned to the cows by the judges of the animals, Mr. R. Baker, Gaunston; Mr. H. Smith, The Grove, Cropwell Butter ; and Mr. R. (3. F. Howard, Temple Brewer ; and by the analyst, their conclusions being arrived at quite independently of one another. 1028.73 1034.87 1034.21 Report on the analyses of samples taken from the miik yielded, on the morning of the 15th May, 1884, by the cows entered under class 21, at the Newark Agricultural Show :- Per- oentage Composition. 13*287 1993 1-553 2.946 12.014 0930 1.361 2.891 21.364 6.882 2.326 3.808 169~.Shorthorn. 1 2.375 w I I I I 86‘40 1 13.60 I 3-81 I 9-79 1 0‘83 Total yield expressed in pounds weight. No. 168 is extraordinarily rich in fat, and is of good quality in every other respect. No. 168 and No. 169 B. are milks of good quality, the former being slightlyTHE ANALYST. 111 the richer of the two, but the quantity of it yielded was not much more than one-half of the latter. The terms of the prize stipulate that the quality of the milk shall be considered in conjunction with the quantity; therefore, in the latter part of the table, I have given the actual weight in pounds of the several ingredients in the total yield of the milks, and, assigning their commercial value to each of these, I am of opinion that the first prize should be awarded to No.168 and the second prize to No. 169 3. Grantham, 16th May, 1884. ALFRED ASHBY. MANGANESE IN MARBLE. M. DIEULAFAIT has shown that manganese in the state of bicarbonate exists in the waters of all seas and oceans ; and M. Berthelob has pointed out that, in contact with oxygen, this bicarbonate becomes bioxide. I t follows that oxides of manganese must; be produced in large quantity in the ocean, and sinking by their weight, must accumu- late on the ocean bed. This corollary explains the existence of the large quantities of bioxide of manganese concretions and manganiferous mud found in the sea bed. It also explains the existence of manganese in the FrencE and English chalks of the secondary period ; also the fact recently discovered by M. Dieulafait, that the well-known artidic marbles of Carara, Paros, and the Pyrenees are comparatively rich in manganese. There are two kinds of Carara marble; the ordinary, which has a bluish tinge on fracture, and the statutary marble, which is very pure and white. The well-known chemical reaction .showed manganese in both kinds. Parian marble, which has larger grains than Carara, also showed manganese in even greater proportion than the Carara ; and the Pyrenean marbles, which resemble the Carara in being of two qualities, also contain manganese in about the same proportion. The agreement in proportion aeems to indicate a similarity of cause for the presence of the manganese.-8cimt@c Amvicaa.
