lM-anches, leaves and spherical lloats of the gulf weed. We 

 were greatly interested in watching the branching streams 

 of protoplasm issuing from the nematophores, which are so 

 characteristic of the Plumularida.'. A small sertularian com- 

 pleted the list of hydroids found on the gulf weed at this time. 



To sum up, the total list of animals which we collected, 

 which w^ere leading a wandering life as they followed the 

 fortunes of the sargasso weed, was as follows: Fishes four, 

 crustaceans live, mollusks three, worms two, bryozoa one. 

 hydroids eight, — making twenty-three in all, and affording a 

 stud}- of great value to those whom the merciless seasickness 

 would allow to work. 



On Tuesday, May 9th. the wind was northeast and worked 

 around later to the east, the barometer sinking toward even- 

 ing. The weather being squalh', the vessel was kept under 

 reefed mainsail and foresail. The study of sea weed was con- 

 tituied by those well enough to care for it. The occupation 

 of dipping up the weed took the attention of some from their 

 distress, and doubtless hastened their recovery. The east 

 wind forced us to sail in the trough of the sea, and greatly 

 aggravated the rolling of the vessel, although the " Emily " 

 proved remarkably dry, more so than many much larger ves- 

 sels would have been under similar circumstances. 



From this time until we reached Egg Island, the schooner 

 passed through large areas thickly dotted with Liiiergxs nicr- 

 riin'iis, a small thimble-shaped jelly-fish, which, with others, 

 has formed the basis of an interesting study by Dr. J. 

 Walter Fewkes. This afforded an excellent opportunit}' for 

 our students to become acquainted with the general structure 

 of the medusa.% and a class was formed, microscopes being 

 brought up and used on the cabin top. With Dr. Fewkes' 

 excellent account before them, and an abundance of material 

 for dissection, a very satisfactory hour was spent with Lincrges. 



At night the brilliancy of the phosphorescence of the sea 

 claimed our attention. The dip nets were again brought into 

 requisition, when it was found that by far the greater part of 

 the phosphorescence was due to this same Liiicrgcs.
