The American observer Ingersoll reported at this time that "as to the accuracy of the bombing of military objectives, here I make no qualifications. The aim is surprisingly, astonishingly, amazingly inaccurate ... The physical damage to civilian London, to sum up, was more general and more extensive than I had imagined. The damage to military targets much less", and stated that he had seen numerous examples of untouched targets surrounded by buildings destroyed by errant bombs. For example, in two months of bombing, Battersea Power Station, perhaps the largest single target in London, had only received one minor hit ("a nick"). No bridge over the Thames had been hit, and the docks were still functioning despite great damage. An airfield was hit 56 times but the runways were never damaged and the field was never out of operation, despite German pilots' familiarity with it from prewar commercial flights. Ingersoll wrote that the difference between the failure of the German campaign against military targets versus its success in continental Europe was the RAF retaining control of the air.:7980,174
How many bridges over the Thames were struck?

Studies of nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all material excreted and eliminated from the body (in urine and feces). Comparing the food to the waste can help determine the specific compounds and elements absorbed and metabolized in the body. The effects of nutrients may only be discernible over an extended period, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of animal nutrition is still slowly evolving.
What needs to be compared to the waste products from humans to determine what is absorbed in the body?
food

The city has an average elevation of 43 metres (141 ft). Its highest elevations are two hills: the Cerro de Montevideo and the Cerro de la Victoria, with the highest point, the peak of Cerro de Montevideo, crowned by a fortress, the Fortaleza del Cerro at a height of 134 metres (440 ft). Closest cities by road are Las Piedras to the north and the so-called Ciudad de la Costa (a conglomeration of coastal towns) to the east, both in the range of 20 to 25 kilometres (16 mi) from the city center. The approximate distances to the neighbouring department capitals by road are, 90 kilometres (56 mi) to San Jose de Mayo (San Jose Department) and 46 kilometres (29 mi) to Canelones (Canelones Department).
