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 Algae maintain 

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

 cases would be thrown away.
