the seaweeds 
Plants which do not adhere by their own mucilage can be fixed m posi- 
tion by strips of adhesive linen tape. 
Many of the coarser Brown Weeds if pressed on the paper stain it 
badly; it is as well to dry them between the newspaper (with muslin) 
first,' and then to fasten them on the mounting paper by strips of tape. 
A very few weeds, such as Sarcomenia, break up and dissolve in fresh 
water, and had better be mounted in seawater. 
If the colour of Red Weeds runs, when the plants are placed in fresh 
water, they should be hurried through and the mounts carefully swabbed 
and dried before putting in the press. 
When dry, the mounts should be labelled, showing the locality, the 
month and year, and the collector’s name. They can then be best kept 
in cardboard boxes of appropriate size, classified according to their 
relationships. The boxes in the Sydney Herbarium are ISm. by 12m., 
and 3in. deep.
