40. Laminaria LONGICRURIS, De la Pyl. Halifax, MacKay and Harvey. Stipes three or 



four yards long have been observed. Prof. Lawsou, of Dalhousie College, says that 

 on taking charge of chemistry on his arrival at Halifax he could get no rubber 

 tubing in the city. While his order was coming, he used the hollow stipes of this 

 seaweed, which is always cast up in abundance on the Haliftix coast, and found 

 it to answer splendidly for the conduction of gas, MacKay. Around Grand 

 Manan and the southern coast of New Brunswick the forms of Laminariœ are 

 variable and confusing, the two following species {L. saccliurina and L. digilula) 

 being most abundant, Hay.
