the Ascocctrp in Monctscns. x 7 1 
contain many large fatty-looking globules and granules. The 
side branches, however, are in many cases filled with dense, 
semi-transparent protoplasm. In certain of these a small 
terminal cell is cut off by the formation of a transverse 
septum a little distance below the tip (Fig. 2, o). Immediately 
below the septum a small lateral protuberance makes its 
appearance (see Fig. 2, b), the development of which causes the 
terminal cell to become bent at a slight angle from the direction 
of growth of the rest of the hypha. This protuberance then 
becomes the main growing point of the hypha, and no further 
growth takes place in the direction of the previous growth, but 
the developing hypha instead becomes closely applied to the 
stationary terminal cell and following its course, at the same 
time pushing it more and more from its original position, until 
eventually it assumes a direction more or less at right angles 
to the parent hypha (see Fig. 2, c, d , e ). The terminal cell 
usually grows but little after its formation, .but in some cases 
a more considerable increase in length, and even branching 
and conidial formation, occur (see Fig. 3, a and b). 
Occasionally a similar process occurs at a considerable 
distance from the tip of a hypha, the new growing point 
developing immediately beneath a transverse septum and 
proceeding, as in the previous case, to bend the apical portion 
of the hypha from its original course (see Fig. 4); on some 
occasions also immediately beneath a conidium (see Fig. 6), or 
beneath the lowest member of a chain of conidia (see Fig. 7). 
In both instances the subsequent development of the new 
growing point is similar. As already stated, it grows into 
a small hypha closely applied to the apical portion of the 
original hypha. Its course along this is usually almost 
strictly parallel with it but slightly curling round it, but in 
some cases a very pronounced spiral winding occurs, to the 
extent at times of more than one complete revolution (see 
Fig. 5). The growth in length of this hypha is limited, 
rarely exceeding 40 ju. By the time that the limit of its 
growth in length has been reached, a septum has been 
formed in the neighbourhood of its point of origin (see
