The entry of gases into, and exit from, the cells, as well as the actual exhalation of watery vapour from the latter, take place in the intercellular space system of which the stomata are the outlets.
These show that a definite intake of carbon dioxide is always accompanied by an exhalation of an equal volume of oxygen.
It is marked by the constant and continuous absorption of a certain quantity of oxygen and bythe exhalation of a certain volume of carbon dioxide and water vapour.
One of the constant features of respirationthe exhalation of carbon dioxide can still be observed.
After the disastrous defeat of Leipzig (r 7th-19th Dctober 1813), when French domination in Germany and Italy -vanished like an exhalation, the allies gave Napoleon another opportunity to come to terms. The overtures known as the Frankfcrt terms were ostensibly an answer to the request for information which Napoleon made at the field of Leipzig.
