Page 427 - Although their presence was demonstrated in one case on the twenty-first day after addition to the water, still there appeared to be no initial or subsequent multiplication of the bacilli. 14. In our experiments in washing infected oysters in a stream of clean sea-water the results were definite and uniform ; there was a great diminution or total disappearance of the typhoid bacilli in from one to seven days. 15. The colon group of bacilli is frequently found in shell-fish as sold in...
Page 185 - ... for these periods of feeding show that on rich pasturage their milk carried from 2.65 to 5.8 per cent, with an average of 4 per cent of butter fat, and that on scant stable feeding the milk carried from 1.10 to 4.6 per cent, with an average of 3.25 per cent of butter fat. In discussing these results the author concludes that the fat content of milk can not be increased at will by increasing a normal ration, but, on the other hand, that it can be greatly decreased by scant and poor rations. If...
Page 422 - Investigations conducted by the Biological Survey have shown that the northward distribution of terrestrial animals and plants is governed by the sum of the positive temperatures for the entire season of growth and reproduction, and that the southward distribution is governed by the mean temperature of a brief period during the hottest part of the year.
Page 699 - ... by the very able and distinguished educators and scientists connected with these colleges furnish ample assurance that the consummation of the great and leading object sought by them is only a question of time. The material already collected in the bureaus and departments of the Government furnishes a rich mine of educational wealth that will not be permitted to remain forever undeveloped. This material is now being constantly enriched by the most valuable additions to its present enormous wealth....
Page 373 - ... by burning ethyl alcohol within the chamber. In the electrical tests the measurements of heat generated and found were practically identical. In the alcohol tests the average amounts found by actual experiment were: For carbon, 99.9 per cent; hydrogen, 100.6 per cent; and heat, 99.9 per cent of the theoretical amounts. It thus appears that this apparatus when used for the analysis of alcohol and the determination of its heat of combustion gives results nearly, if not quite, as accurate as are...
Page 13 - Now, certain growers of beet seed in the north of France once formed the idea — thinking, no doubt, in this way to improve their varieties — of growing the plants which were to be used as seed stocks in very rich, deeply worked soil where they were very much crowded -together; so much so that 16 to 20, or even more, grew on one square meter of ground. The result was that the beet assumed the form and later the length of a whipstock. They were not branched because the roots were very closely crowded...
Page 183 - Kafir-corn meal alone—a gain of 868 pounds of pork per ton of alfalfa hay. These results are not due to the feeding value of the alfalfa alone, but also to its influence in aiding the hogs to better digest the Kafir corn. The alfalfa hay also gave a variety to the ration, making it more appetizing and inducing the hogs to eat more grain. The ten hogs having grain alone ate 3,885 pounds of dry Kafir-corn meal, while the ten hogs having hay and grain ate 4,679 pounds of the Kafir-corn meal and 656...
Page 108 - ... per cent of ammonium chloride is precipitated by making it slightly ammoniacal, the precipitate being washed in slightly ammoniacal wash-water. In general, however, and especially when more ammonium chloride than this proportion, or more magnesium salt than twice the amount theoretically necessary, is present, it is safer to decant the supernatant liquid from the precipitate (through the filter to be used subsequently to hold the phosphate), to dissolve the precipitate in a little hydrochloric...
Page 385 - ... trip, and then sunk to the normal. In two cases the effects of fatigue are reported where 10 cows were driven 10 miles and shipped 50 miles by railroad. While considerable individual variation was observed on the average, the quantity of milk was lowered as an immediate result, but normal flow was nearly restored by the end of the second day. The fat percentage dropped during the first day and was decidedly increased the second day, remaining a little high during the next few days, as compared...
Page 13 - The result was that the beet assumed the form and later the length of a whipstock. They were not branched because the roots were very closely crowded together. Their sugar content was abnormally high as a result of their growing so close together, and the conclusions drawn from the form of the roots and their sugar content, as determined in the laboratory, were tainted with error because they did not represent qualities truly acquired, but modifications accidentally imposed by external conditions....
