SOMETHING NEW AND CHEAP. 
By special request of many of my clients, I have issued a small leaflet entitled, 
‘‘ Valuable Hints to Collectors.’’ This little work will be found most useful to 
the advanced collector as well as the beginner and one of the hints alone is worth more 
than the cost of the work. Amongst other matters it deals with treatment of Ova, Larvee 
and Pupe in captivity, cleaning insects for grease, killing and setting, and gives some 
very useful substitute foodplants. Price 9d. only, post free. 
Write for latest price lists of Ova, Larve, Pups, and Set Insects, the smallest order 
thankfully received. Don’t forget I can supply all apparatus at usual prices. 
Remember my Relaxing Tins and Text-book.
