to a demand, is willing to make arrangements for a 

 special class in Elementary Marine Biology, to illustrate 

 the principles of nature-study, and to be held at the Port 

 Erin Biological Station during the Easter holidays, 1905. 

 The Station is a new building situated on the sea-shore, 

 and is admirably adapted in every respect for classes of 

 this description. 



A large laboratory on the first floor, provided with 

 fourteen windows, will be set aside wholly for 'this purpose 

 during the time of the class. Each member of the class 

 will occupy a table or workplace opposite a window, and 

 will be provided with the necessary animals (or when 

 possible, and as is much better, will be shown how to 

 collect them himself), salt and fresh water, and all 

 materials and apparatus necessary for the work. 



The course is necessarily restricted to the Easter 

 holidays, and will extend from a Saturday to a Saturday 

 in April, in the week that is found most convenient to 

 teachers. If, however, any are able and willing to stay 

 for a longer period, further arrangements can be made at 

 the time. 



The class will be limited to twelve students, each of 

 whom will pay 5s. to the L.M.B.C. for the use of the 

 laboratory, and in addition a tuition fee of 5s. These fees 

 should be remitted to Mr. Chadwick before the opening 

 of the class. Ts"o definite time table of the class work can 

 be drawn up, and the time and nature of the work will 

 depend largely on the tides, weather, &c. Speaking 

 generally, however, the class will spend the morning in 

 the laboratory, examining animals in the living condition, 

 and making simple biological experiments thereon. In 

 the afternoons collecting excursions, with the object of 

 studying the animals in their natural surroundings, and 

 also expeditions for collecting and dredging from boats,
