Corn Weevils. 



of gum arabic and i per cent, formalin. Outward appear- 

 ance inferior to those in foregoing tests ; yolks attached to 

 shell ; albumen decidedly discoloured ; odour not marked ; 

 air space normal ; appearance of broken egg much inferior 

 to those in preceding test ; developing marked flavour on 

 poaching. 



5. Eggs continuously immersed in 5 per cent, gum arabic, 

 plus 5 per cent, salicylic acid. Preserving solution quite 

 mouldy and with a very bad smell. Egg-shells quite soft. 

 The broken egg, though not unsightly, had a most 

 nauseating odour, and was quite unfit for food. 



6. Eggs continuously immersed in 5 per cent, dextrin plus 

 5 per. cent salicylic acid. Preserving solution very mouldy 

 and smelling badly. Egg-shells soft, and contents unfit for 

 food. 



7. Eggs dipped momentarily in dilute sulphuric acid, then 

 washed and stored in a large bottle. All exceedingly bad ; 

 contents very offensive, / 



8. Eggs dipped momentarily in sulphuric acid, washed 

 and dipped in alkaline ammonium oxalate, then stored in 

 large bottle. All the eggs very bad, and contents offensive. 



These experiments corroborate many of the results 

 obtained in the previous year, and are held to afford further 

 proof of the excellence of the eggs preserved in saturated 

 lime-water. Mr. Shutt thinks that, on the whole, 2 per cent, 

 sodium, silicate gives better results than the 10 per cent, 

 solution, but he is also of the opinion that lime-water is 

 superior to both as an egg preservative. " Moreover, it is 

 cheaper and pleasanter to handle." 



Corn Weevils [Calandra Granaria). 

 This beetle and the closely related Rice Weevil [Calandra 

 Oryzce) are more destructive in granaries, stores, and barns 

 than any other known corn pests. But the ravages of this 

 insect are not confined to stored corn ; for cereals in transit 

 are also liable to its attack, and cargoes of corn from abroad
