in. and leave it so that another could see it. Thus equipped 

 we essayed some of the regions till then denied to us. Diatoms 

 were a source of great interest, and rotifers now showed their 

 cilia and mastaxes on demand. The first sight of a flame cell 

 in a rotifer marked the new advance. Now that the mechanical 

 difiiculties were settled, the " Society " acquired a new popularity. 

 One lucky dip taken direct from the little stream in the village 

 on to the slip, contained half a dozen lusty Hydatinae, and hosts 

 of Euglenae and slipper animalcules. Such sights as these were 

 very popular, and Madame, our excellent hostess, became an 

 interested visitor of the Society. I have a charming re- 

 collection of the visit of her two little children to a seance : 

 the wee girl, after a lot of coaxing, took an eager hurried peep 

 at the wriggly things down the tube, and clung with frightened 

 pleasure to her mother's skirt. Melicerta we found again away 

 towards the Estuary. 



The floscules found in the days of model No. 1 we never found 

 again ; but the finest haul of diatoms and desmids I've ever 

 had we found under two feet of water in a delta-shaped patch 

 where one clear stream met another at right angles. In surface 

 water lying on a field for several weeks I found Pterodina valvata, 

 considered rare by Hudson and Grosse. Its delicate lorica 

 folded at each side was very transparent, almost invisible. In 

 the marshes we found Volvox and the purple Stentor. Along the 

 river bank, a mile or two from the sea, we once found a hoof mark 

 filled with water faintly milky -looking ; this was due to count- 

 less hosts of Synchaeta, a form rather smaller than S. pectinata, 

 of which, however, there were a fair number. A rotifer talked of 

 for long before we found it was Dinocharis, but at last we captured 

 this dainty form. We paid a considerable amount of attention to 

 moss, because there was plenty about the district. The roofs 

 of several places in the village yielded Philodina citrina and 

 P. roseola, fine big forms, as well as more ordinary forms like 

 Rotifer vulgaris; an Adineta with curious sudden movement in 

 crawling. Some rather unusual infusorians we took in the moss, 

 among which I remember most clearly a species of Folliculina. 

 We kept Hydatina under observation, and managed to get the 

 fourth generation of one individual by the cobbler's wax and 

 thick cover-glass method. The " Society " was generally fortunate 

 in its expeditions. A little knob of moss, about the size of half a
