KEEPING EGGS. 
Hundreds of rules have been given for putting up 
cheap eggs, to be kept until prices rise in late autumn 
and winter. The most careful experiments on record 
have been made by German scientists. 
After eight months of preservation, 400 eggs, divided 
into 20 different parcels for that many methods of exper- 
iment, were examined, with heterogeneous results. 
Upon opening for use the eggs presented the following 
results, according to the parcels originally numbered : 
1. Eggs put up for preservation in salt water were all 
bad; not rotten, but uneatable, the salt having pene- 
trated into the eggs. 2. Wrapped in paper, 80 per cent 
bad. 3. Preserved in a solution of salicylic acid and 
glycerine, 80 per cent bad. 4. Rubbed with salt, 70 
per cent bad. 5. Preserved in bran, 70 per cent bad. 
6. Provided with a covering of paraffin, 70 per cent bad. 
%. Varnished with a solution of glycerine and salicylic 
acid, 70 per cent bad. 8. Put in boiling water for 12 to 
15 seconds, 50 per cent bad. 9. Treated with a solution 
of alum, 50 per cent bad. 10. Put in a solution of sali- 
cylic acid, 50 per cent bad. 11. Varnished with water 
glass, 40 per cent bad. 12. Varnished with collodion, 
40 per cent bad. 13. Covered with lac (probably shel- 
lac varnish), 49 per cent bad. 14. Varnished with 
sward, 20 per cent bad. 15. Preserved in wood ashes, 
20 per cent bad. 16. Treated with boric acid and water 
glass, 20 per cent bad. 17. Treated with manganate of 
potash, 20 per cent bad. 18, Varnished with vaseline, 
all good. 19, Preserved in lime water, all good. 20. 
Preserved in a solution of water glass, all good. 
Water Glass is a soluble silicate of soda, and makes 
the shell air-tight. Use one part, by measure, of water 
glass to ten parts water. It appears to be the best-of 
the methods. Before boiling eggs which have been kept
