With a division of the curves over 5 bundles the diagrams: 
B,+ B,+ B,+ B,+B, , B+ B,+8,+8,+ 8, 
and B,+ B, + B,+ B,+ B,. 
The first of these diagrams consists of one threecurvical and four 
onecurvical bundles, it is represented in fig. 1 by 0. 
The second and third diagrams consist both of three onecurvical 
and two twocurvical bundles. These diagrams differ, however, mutu- 
ally, because the bundles of curves have another position with 
respect to one another. The second is represented in fig. 1 by c 
the third by d. 
When dividing the curves over three bundles the diagrams: 
BBB, VB. Be ee Be B Brande 8, BA DEN 
arise. The first consists of one fivecurvical and two onecurvical 
bundles; we find it in fig. 2e. The second consists of one onecurvical, 
one twocurvical and one fourcurvical bundle [fig. 27]. The third 
consists of one onecurvical and two threecurvical bundles | fig. 2] ; 
the fourth consists of one threecurvical and two twocurvical bundles 
(fig. 2h]. 
Consequently we find that in a quinary system exist the eight 
types of the P,7-diagram, which are drawn in the figs. 1 and 2. 
In the previous communication IV we have deduced the type of 
the P,T-diagram for a definite case of a system of five components. 
For this we found the symbolical diagram 20 (IV); this consists of 
three onecurvieal bundles (viz. V’, U’ and Rk’) and of two two- 
curvical bundles (viz. P’7” and S’Q’). We have seen above that in 
this case two types may be distinguished; it is apparent from the 
symbolical diagram that it belongs to the type: 6, + 6, + B, + 
+ B, + B,; consequently it may be represented by fig. 1 d. 
6. Senary systems [six components; eight curves]. 
When dividing eight curves into an odd number of bundles we 
may distinguish again three principal types, viz. a division into 
7, 5 or 3 bundles. We then find the following eleven types of dia- . 
grams in which for the sake of simplification the letter B is 
omitted.

The reader can easily draw or represent symbolically these types 
of P,T-diagrams.
