J. G. WALLER ON PARASITIC VEGETABLE ORGANISMS. 353 



the four larger figures, one seems to be nearly matured, and is of a 

 globular form, and its tubular stem is free from all granular 

 matter. One is on a membranous expansion, and some germina- 

 tion is apparent ; another shows two mycelious threads issuing 

 from it. In the upper portion of the canal, where the granular 

 matter is partially obsolete from exposure to the surface, there are 

 globose objects, perhaps oospores, and still farther are minute 

 granules which appear to be escaping. Near to this is a depending 

 sporangium, in which are seen four sporidia. This was from a par- 

 ticle found in the Outer Gabbard, but in another specimen from 

 the Galloper the same form of sporangium is repeated twice or 

 thrice. The relation this bears to the rest in its fructification is 

 not a matter on which I can pretend to give any information or 

 opinion. 



There is another character often visible which has not yet been 

 described. It may be called a glomerus, for it has a globose form 

 very much larger in proportion than any other part, well shown in 

 PI. XIV., Figs. 6, 7, and PI. XV., Figs. 3, 4. If its relative size 

 can be an indication of its importance, that must be great, and it 

 may be that its place is amongst resting spores. Occasionally a 

 confluent and amorphous mass is seen, always at the edge of the 

 particle, partaking of the same character. 



It appeared to me to be necessary to examine, where possible, 

 other of the sand deposits in the vicinity of the group wherein 

 these organisms were found, as also of others off the coast, to as- 

 certain whether they were peculiar to them alone or might be found 

 dispersed about them. There is a long sand lying off the Suffolk 

 coast called the " Shipwash," eight miles distant from the shore, 

 and about eleven from the Inner Gabbard, between which and it 

 there is an average of 14. to 24 fathoms. Some traces exist in this 

 of them, but not in quantity. So, also, from a sounding taken at 

 the Kentish Knock, about 11 miles more southerly, in 16 fathoms, 

 also in the Long Sand, which stretches to the Thames entrance, 

 they are to be found, and possibly in many other of the deposits, 

 where calcareous particles are present. Pursuing the subject, I 

 now examined a specimen of the Varne Sand, lying off Dover and 

 Folkestone, but the nearest point of which is seven miles distant. 

 The general appearance of this deposit is similar to those of the 

 Gabbard and Galloper, but not so coarse. It contains the same 

 calcareous particles, and these present us with similar forms, such
