SYSTEMATIC ANALYSIS OF GROUPS. 59 



SECTION III. 

 Circulatory Apparatus. 



134. BLOOD MUST BE CIRCULATED in order to be of 

 avail, and it has been seen that tubes are provided for 

 this purpose. There must be, therefore, an Apparatus 

 for the circulation of Blood, called the B. (Blood) Circu- 

 latory Apparatus ; its Function, B. (Blood) Circulation. 



135. THE CIRCULATION OF BLOOD MUST BE CONTROLL- 

 ED, increased, or diminished, as the necessities of parts 

 require; and as all other controlling influences in the 

 body are nervous, so is this. For the sake of euphony the 

 parts controlling the circulation of blood may be called 

 the N. (Nervous) Circulatory Apparatus.

136. CIRCULATORY APPARATUS . = j N Circulat-ory (ion)- 



137. THE CIRCULATORY APPARATUS is, in fact, to an 

 extent, a part of the Mentory and of the Sanguificatory 

 Apparatus, as Blood-tubes are found in all of them. In 

 the Mentory the tubes are right and left, as the apparatus 

 is ; but in the sanguificatory, as its parts are. (Fig. 48.) 



138. BOTH KINDS OF CIRCULATORY APPARATUS MAY 

 BE INCLUDED with each, which will give six to each 

 Group, though there are only ten in all, as follows. (See 



J.) fSensat-ory (ion). 



G' = [Mot-ory (ion). 



G"= TRespirat-ory (ion) 



(_ Modificat-ory (ion). 



139. THE USES OF EACH KIND OF APPARATUS will 

 determine their varieties, and of how many and what 

 kind of parts or organs each apparatus consists. That 

 Analysis will be the object of the next chapter.
