during the day time bears a small bubble of oxygen. My only fear is tbey 

 will soon become too many for me. Witb regard to the Adirdce, during the 

 dark winter months they seemed very unhealthy and dwindled down to not 

 more than half their original size and bulk, but the warm weather and sun- 

 shine of early spring seemed to re-invigorate them and they are now as large 

 as ever. This creature is a most beautiful object, as, fixed to the rocks it 

 expands its finger-like tentacula, alternating with the little sky-blue knobs, 

 that surround them ; frequently when one of the larger ones has been 

 near the surface, and fully expanded, I have placed the tip of my finger 

 amongst the tentacles, round which they almost immediately closed, my 

 finger at the same time experiencing a slight shock, similar to galvanism. 

 During the early part of March, I had an addition to my family of Anemones 

 by the appearance of more than a score young ones dotted all over the bottom 

 of the vase and the rock — each about the size of a small pea — some yel- 

 lowish brown others crimson. Another spontaneous addition rather 

 astonished me— a few days back whilst taking my customary peep into the 

 vase in the morning, I was agreably surprised to find tAvo Chifons sticking 

 to the topmost stone, and both of them exactly of tlie same size. One only 

 was put in — of that I am certain. I find, however, on reference Rymer 

 Jones that some of these lower orders of Brachiapoda are hermaphrodite and 

 self-generating, which of course accounts for the appearance of my second 

 Chiton. On taking out a few drops of the water from amongst a tangled 

 piece of sea- weed and placing them in the animalcule-cage under the micros- 

 cope I found innumerable Infusoria and a few Rotifer ce. In looking for these 

 minute forms a month or two after I had fitted up the vase I could not find 

 any trace of them. In concluding this short sketch of my experience of the 

 marine aquarium I may repeat that the water has never been changed since 

 it was first put in ; that it has been syringed a little recently every morning, 

 and more frequently at first than lately, and the water constantly reple- 

 nished as it evaporated, up to a fixed mark.
