some scores of these little bivalve shells in an unbroken state. llic 

 sack however gradually emptied itself into the gizzard ; and in this 

 shelly mill, the shells and their contents were reduced to powder, or 

 rather fine paste, well fitted, we doubt not, to be wholesome nutri- 

 ment for the industrious little marine miller. Verily I do regret that 

 I have not turned to better account the little modicum of anatomical 

 knowledge which I got many long years ago in the University of Ed- 

 inburgh. Could I have followed out my researches into the workings 

 of this beautiful mollusk, I am sure that I should have seen still greater 

 cause to admire the goodness and wisdom and power of that benig- 

 nant Being, who, while he rises far above the highest thoughts of the 

 highest, is not for a moment forgetful of the lowest of the creatures he 

 has forined. 



T saw nothing uncommon in Ichthyology or Ornithology, but de- 

 voted some time to the search for Zoophytes, and with some little 

 success. Among others I obtained one very fine specimen of Tubu- 

 lipora orbiculus, much larger and more hemispherical than those, 

 occuri'ing on the Ayrshire coast, which are found on Laminaria sac- 

 charina, while the Arran one was on an old shell. I also found one 

 remarkably fine example of the Tubulipora lobata of Hassall, but in 

 a much more perfect state than the one which that gentleman has fi- 

 gured. Two fine specimens of Antennularia antennina var. ramosa 

 were given to me by fishermen ; and a very fine example of Plumu- 

 laria myriophyllum with vesicles ; these vesicles, which I had never 

 before seen, are as remarkable as those of P. cristata. As these were 

 from deep water, they show what fine things might be obtained by 

 dredging. A pretty Beroe was found, of a kind not uncommon on 

 the Ayrshire coast ; clear as crystal, melon-shaped, with its countless.
