then place the Algae in about 100 c.cm. sea-water, and add at 

 intervals of a quarter of an hour 5 c.cm. alcohol (96 per cent.), until 

 there are added 25 c.cm. Transfer the plants to a 25 per cent, 

 alcoholic solution and add as before at intervals of a quarter of an 

 hour 5 c.cm. of alcohol, until 125 c.cm. of the solution contain 

 50 c.cm. alcohol. Then transfer gradually to 50, 60, 70, 80, 90 per 

 cent, alcohol, and allow to harden." As most Red Alga^ maintain 

 their colour remarkably well in herbaria, all this trouble in most 

 cases would be thrown away.
