Experiments With Sparrows

Count Morozzo placed successively several full-grown sparrows under a

glass receiver, inverted over water. It was filled with atmospheric

air, and afterwards with vital air. He found,

First.--That in atmospheric air, HOURS MIN.

The first sparrow lived 3 0

The second sparrow lived 0 3

The third sparrow lived 0 1

r /> The water rose in the vessels eight lines during the life of the

first; four during the life of the second; and the third produced no


Second.--In vital air or oxygen, HOURS MIN.

The first sparrow lived 5 23

The second 2 10

The third 1 30

The fourth 1 10

The fifth 0 30

The sixth 0 47

The seventh 0 27

The eighth 0 30

The ninth 0 22

The tenth 0 21

The above experiments elicit the following conclusions:--1. That an

animal will live longer in vital than in atmospheric air.--2. That one

animal can live in air, in which another has died.--3. That,

independently of air, some respect must be had to the constitution of

the animal; for the sixth lived 47 minutes, the fifth only thirty.--4.

That there is either an absorption of air, or the production of a new

kind of air, which is absorbed by the water as it rises.
