Here above the author describes a new apparatus ("meghetometro") to measure the body volume "in vivo" of infants which will also be utilizable for children and adults, if made of larger size. The working principle of the "meghetometro" is the following. The subject under examination will be put into a container filler with air and his volume will be drawn from the pressure variations produced in the gaseous matter (air) as a consequence of the (known) volume variation of the container itself. The value of the volume is of course only a factor that enables us to go back to the specific weight of the subject taken into consideration. We believe the specific weight may have a considerable clinical importance, for example as a symptom of some cases of disendocrinopathy or as an evaluation element of dehydration and edema.
作者在此描述了一种新仪器（“体重测量仪”），用于测量婴儿的“活体”身体体积，如果制成更大尺寸，也可用于儿童和成人。“体重测量仪”的工作原理如下。接受检查的对象将被放入一个充满空气的容器中，其体积将根据容器本身（已知）的体积变化所导致的气态物质（空气）压力变化来得出。体积值当然只是一个使我们能够追溯到所考虑对象比重的因素。我们认为比重可能具有相当大的临床重要性，例如作为某些内分泌病病例的一个症状，或作为脱水和水肿的评估要素。
