Anesthetizing apparatus capable of use with anesthetic agents requiring an in-line arrangement, as well as those necessitating the use of an out-of-line arrangement. The apparatus includes the main body member having a plurality of internal passages which provide a closed system or circuit, and further defining two separate and distinct paths within said circuit. Waste gas purging means, vaporizer means and oxygen inlet means are connected to the body member in communication with said internal passages. The apparatus further includes control means for selectively providing one or the other of said paths for the carbon dioxide free waste gas leaving the purging means. Accordingly, purged waste gas to be re-circulated to the animal can be either mixed with oxygen and then subjected to the vaporizer (in-line arrangement), or said gas may bypass the vaporizer and be mixed with oxygen that has previously been subjected to the vaporizing process (out-of-line arrangement). In addition there is provided a novel construction for the main body member, wherein a pair of opposed plate members are utilized, one said member having channels formed therein such that upon assembly said channels are covered to define the internal passages of the system
