Page 31 - As an immediate effect of the manifestation of mechanical force, we see, that a part of the muscular substance loses its vital properties, its character of life ; that this portion separates from the living part, and loses its capacity of growth and its power of resistance. We find that this change of properties is accompanied by the entrance of a foreign body (oxygen) into the composition of the muscular...
Page 31 - ... vital properties, its character of life ; that this portion separates from the living part, and loses its capacity of growth and its power of resistance. We find that this change of properties is accompanied by the entrance of a foreign body (oxygen) into the composition of the muscular fibre (just as the acid lost its chemical character by combining with zinc) ; and all experience proves, that this conversion of living muscular fibre into compounds destitute of vitality is accelerated or retarded...
Page 30 - ... constituents of food, not only with the formation in the animal body of the compounds containing nitrogen, but also •with the development of muscular power, and, on the other, of the general relationship of the non-nitrogenous constituents of food with respiration, the development of heat, and the deposition of animal fat, he concluded that the relative value of different foods, as such, was to a great extent dependent on, and even measurable by, the proportion of nitrogenous constituents which...
Page 69 - ... consumed by a given weight of animal, within a given time, and the amount of increase obtained from a given weight of food. The results, which formed the subject of the present communication, afforded further illustration of some of the points brought forward...
Page 1 - The right way to dispose of town sewage is to apply it continuously to the land and it is by such application that the pollution of rivers can be avoided.
Page 27 - That the direct result of the general application of town sewage to grass land would be an enormous increase in the production of milk (butter and cheese) and meat, whilst by the consumption of the grass a large amount of solid manure, applicable to arable land and crops generally, would be produced.
Page 129 - Commission appointed to inquire into the best mode of distributing the Sewage of Towns, and applying it to beneficial and profitable uses.
Page 2 - Second, that where town populations are injured or endangered in health by a retention of cesspool matter among them, the towns may reasonably be required to provide a system of sewers for its removal. " And should the law, as it stands, be found insufficient to enable towns to take land for sewage application, it would, in our opinion, be expedient that the legislature should give them powers for that purpose.
Page 69 - When cut and given to fattening oxen tied up under cover, more sewaged than unsewaged grass, reckoned in the fresh or green state, was both consumed by a given weight of animal within a given time, and required to produce a given weight of increase ; but, of real dry or solid substance, less of that of the sewaged than of the unsewaged grass was required to produce a given effect. 11. When cut grass was given alone the result was very unsatisfactory ; but when oilcake was given in addition the amount...
Page 71 - Rugby represent the excretal and other matters of from 17 to 18 average individuals of a mixed population of both sexes and all ages for a year, and contain ammonia equal to that in from 11 to 12 cwts. of Peruvian guano ; or about 1,700 tons of such sewage would contain nitrogen reckoned as ammonia equal to that in 1 ton of Peruvian guano. 23. It is estimated that there are at Rugby, including rainfall, etc., on the average from 55 to GO tons of sewage per head of the population per annum.
