bought annually millions of eggs in Hungary, to make 

 albumen from the white, but did not know what to do 

 with the yolk of the eggs. He offered it by the hundred 

 weight and ton to pastry cooks and to leather dressers : 

 he tried to salt it, and he tried to invent candied yolk of 

 eggs; but nobody would have it. I suggested to him to 

 preserve the yolks by simply evaporating" the moisture in 

 it at & low heat and in a chamber from which the air was 

 exhausted, whereby very rapid evaporation at a low 

 heat, without the alteration of chemical combination of 

 substances, resulting from cooking, becomes possible. 

 My friend acted on the suggestion, and the product 

 entirely answered my expectation of proving a very 

 useful food for rearing Pheasants, bringing up chickens, 

 and as a food for cage birds." When fresh eggs are used 

 they should be as newly laid as possible, boiled gently 

 until quite hard, and then granulated b}- pressing through 

 a fine sieve. 



OX HEART boiled, and then dried in the oven to 

 extract the moisture, may then be grated, and will keep 

 fresh some considerable time if kept in air-tight tin 

 canisters in a cool dr}' place. 



FRUIT AND VEGETABLES, such as pears, apples, 

 elder, privet, ivy, service, and blackberries, red and 

 white currants, bananas, etc., all of which must be ripe, 

 should form the chief portion of the Blackcap's food, 

 and will be partaken of by many other species to their 

 benefit. Carrots, which if kept buried in sand will keep 

 fresh throughout the year, act as a valuable corrective to 

 the heating foods mentioned above, keep the Ijlood cool, 

 and the bowels in a healthy state ; a little finely grated 

 ought to form part of the daily tood mixture. Water- 

 cress, dandelion leaves, or lettuce, finely chopped, may be 

 used in summer instead ; they will form a variet}', and 

 the effect will be mrrch the same. 



BRBvAD that has beeir allowed to become stale, and 

 is then dried in a cool oveir for some hours, so that it 

 may be ground into a fine powder, is a useful addition to 

 the food list, as it keeps the mixture of ants' eggs, dried
