hot seasons it is best to transmit them, bundle by bundle, as they get 
ready, by parcels post. In the rains it is not so advisable to do so if 
the distance be considerable, and if (as in then frequently the case with 
frontier districts) there is likely to be a delay in parcel transmission 
and probably a very inadequate storing accommodation on the part of 
the post office for the articles delayed. It is of little advantage after¬ 
wards to blame the postal authorities : no amount of upbraiding will 
replace a lost collection. As a matter of fact the post office does its 
very best everywhere, and knowing this, one should not incur risks 
where one knows that delays are likely or are even only remotely 
possible. When sending such bundles, it is well to put several sheets 
of news-paper out-side the outermost specimen, and besides a cane 
frame outside all, on both sides, to intersperse cane frames at inter¬ 
vals of about 30 specimens throughout the bundle. The size of 
bundle will be limited by postal regulations : the thicker it is possible 
to make it, provided always the specimens are thoroughly dry, the 
safer its contents will be. Outside the cane frames a covering of the 
momjama cloth should be sewed ; outside this another covering of 
cloth (ordinary drill or long-cloth is excellent) also sewed^ and it is 
far better to tie on a stout tag with the address than to write the 
address on the parcel itself When it is necessary to keep dry speci¬ 
mens for a few months during the rains until considerable numbers 
have accumulated, they may be sent in boxes by the easiest available 
carriage route. If they are to come all the way by cart or rail, it is 
sufficient to line these boxes with wax-cloth momjdma ; this ensures 
the contents remaining dry if the boxes be exposed to passing showers 
at any time. But if in any part of the journey the boxes are to be 
exposed to the risks of ferry or river or sea transit, it is best to put 
them inside a tinlined box (and to have the lining carefully soldered 
down) before despatching them. 
When specimens have to be kept for more than one season, or 
where the collector retains a set of specimens for his owm use, it is 
necessary to poison them. Unless this is done, they are sure to suffer 
and ultimately to be quite destroyed by the depredations of insects. 
Poisoning them, however, is a very simple matter. Some corrosive 
sublimate should be put in strong spirit; may be dropped into a 
gallon of methylated spirit, and as the spirit will not dissolve anything 
like so much, this ensures that it will always have in solution as much 
corrosive sublimate as it can hold. The mixture should be painted on 
with a brush. When all the specimens in a bundle have been poisoned 
on one side, reverse the bundle and paint them on the opposite side; 
never lift or turn a specimen when poisonining iU It is often supposed
