l^ranchcvS, leaves and spherical iloats of the L;'ulf 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 a.nimals which we collected, 

 which were leading a wandering life as they followed the 

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

 crustaceans five, mollusks three, worms two. brvozoa one, 

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

 study 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 squally, the vessel was kept under 

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

 tinued by those w^ell enough to care for it. The occupation 

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

 distress, and doubtless hastened their recover\-. The east 

 wind forced us to sail in the trough of the sea. and greath" 

 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 Lincrgcs iiicr- 

 rnriiis, 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 opportunity for 

 our students to become acquainted with the general structure 

 of the medusae, 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 witii L/iicr<>rs. 



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 b}' far the greater part (^f 

 the phosphorescence was due to this same L/ncrg€$.
