[May, 



stuck ou the centre o£ the glass with some adhesive, but for larger 



specimens I first gum a 

 small (the smaller the bet- 

 ter) piece of cork on the 

 support and pin it on that. 

 It must be pinned from the 

 hack and not quite through 

 otherwise the pin will show 

 in the enlargement and be 

 a decided blemish. I find 

 the best plan is to push the 

 pin through the back of 

 the little piece of cork till 

 the point protrudes a short 

 distance from the front, 

 and then press the insect 

 on that. The advantage 

 of fastening the specimen 

 on to a support of clear 

 glass, some way in front of 

 the background (2), is that 

 it entirely does away with 

 shadow, and so saves the 

 trouble of blocking out the 

 negative as described in my 

 last paper. This idea is 

 not original, as I saw it 

 mentioned in Mr.Watkin's 

 (of Exposure Meter fame) 

 little book, " Exposure 

 Notes." Dr. H. G. Knaggs 

 H also gives some instructions 

 as to photographing with- 

 out shadow in the October 

 No. of the " Entomologist." 

 Unique (or otherwise valu- 

 able) specimens that it is 

 not considered advisable to 

 <K unmount from their cards, 



can be enlarged without shadow if particular care is taken as to the 

 arrangements of the lights.
