Professor Harvey Gibson reports as follows : — 

 " During the Easter vacation a course of instruction 

 on Marine Algae was given at the Station on the same 

 lines as last year, and the course was attended by over 

 twenty senior students from the Botanical Department 

 of the University. 



"Each day a certain area was selected in Port Erin 

 Bay, Flesh wick Bay, or at Port St; Mary, from which 

 Algae were collected and afterwards examined in the 

 laboratory, careful lists of all Algae found in each area 

 being made. In addition to this, short lectures on 

 representative forms were given in the evenings. As 

 a result of examination of the collections, together with 

 those of last year, about fifty species have been identified 

 as occurring in the area over and above those previously 

 recorded. 



" A paper on the Marine Algae of the district is now 

 in preparation, which, it is hoped, will be published in 

 the ' Transactions of the Liverpool Biological Society ' at 

 an early date.
