NOTES FOR GUIDANCE in working out the 
Vertical and Horizontal distribution of the 
British Carboniferous Flora. 
I.—As soon after collection as possible, label all specimens, 
stating— 
(a) Full locality, giving name of pit, if collected at a colliery. 
(2) Giving horizon,* when ascertainable. 
(c) Name of collector. 
TI.— Collect all specimens, however small or uninteresting they 
may appear to be, and give great care to the collection of 
all fructifications—even when fragmentary—whether cones 
or fruit of ferns. 
IIT.—On no account varnish the specimens, and if absolutely 
necessary to apply some preservative medium, use very 
weak, watery glue, and apply it by ‘dabbing’ gently with a 
soft sponge. It need hardly be added that all fingering of 
the surface of the specimen, or rubbing of any kind, ought 
to be avoided. 
On collecting, wrap the fossils up singly in paper at 
once to prevent their being scratched or the carbon dis- 
placed while carrying them home. In mending broken 
specimens, gently heat each part before applying the glue. 
IV.—In packing fossils for transit, wrap each separately in 
paper and pack with additional paper, straw, hay, or shav- 
ings in a strong box. Jever use sawdust, husks, or any 
similar substance for packing. 
V.—All specimens sent to me for examination to be numbered 
and accompanied with a list containing the numbers, 
localities, and any other additional particulars that may 
be thought necessary. Attention to this saves time and 
trouble to all parties. ROBERT KIDSTON.

STIRLING. 
* ‘Horizon,’ 7.e., the name of the coal seam with which the shale was associated that con- 
tained the fossil, or any other particulars that will enable the exact position of the 
rock to be determined from which the fossil has been derived.
