对鸟类骨结构变化与矿物盐代谢关系的研究仅限于观察与产卵有关的变化。几年前，我观察到某些圈养的鸟类（Paridae）在换羽期间腿很软。它们不能像往常那样在笼子里过夜，只能在笼子的地板上坐着。他们经常在这期间死亡。这些研究结果表明，羽毛的形成也可能影响鸟类的羽毛。鹿的鹿角形成的周期性表明，密质骨的相关变化可能发生在这些哺乳动物中，因此包括了白尾鹿的数据。这项工作是在芝加哥Xatiiral历史博物馆的解剖实验室进行的。感谢博物馆为这些藏品所做的工作，特别是工作人员D。D. Davis，A. L.感谢兰德和雷纳·赞格尔的大力协助。伊尔索茨克自然历史调查局的哈罗德汉森提供了拉布拉多标本的材料。
Studies of the structural changes in bone in relation to mineral salt metabolism in birds have becn limited to observation of the changes associated with egg-laying. Somc years ago I observed that certain captive birds (Paridae) had very weak legs during the molt. They could not perch a t night in the usual manner but mere always found sitting on the floor of the cage. They often died during this period. These obscrvatioiis suggested that feather formation may also affect the skelseton in birds. The cyclical nature of antler formation in deer suggests that correlated changes in the compact bone may take place in these mammals, and data on a white-tailed deer have theref ore been included. The work was carried out in the anatomy laboratory of the Chicago Xatiiral History Nuseum. Thanks are due the Museum for the privilege of working on the collections, and especially to membcrs of the staff D. D. Davis, A. L. Rand, and Rainer Zangerl for their much-appreciated assistance. Harold Hansen, of the Ilslinois Natural History Survey, provided material from Labrador specimens.
