DISEASES. 151 



put a sheet of paper between the layers of the quilt so 

 as to prevent the escape of the fumes of the acid as it 

 evaporates. If the weather is warm it will be found 

 in the course of a week that the odour of the foul brood 

 has disappeared, and that the bees (if not too weak in 

 numbers) have cleared the putrid matter out of the 

 cells. It is seldom necessary to refill the comb more 

 than once unless the disease has been re-introduced by 

 infected combs, &c. If foul brood is prevalent in the 

 district it may be well to keep some of the acid always 

 in the hive as a prophylactic. In case of an ordinary 

 ten or eleven-frame hive this can be done while honey 

 is being stored, by putting the acid into a section of 

 empty comb and placing the section at the end of the 

 crate farthest from the hive entrance, so that the acid 

 has to pass over all the combs before the bees fan it 

 out. ' Storified ' hives can be treated by filling a comb 

 and hanging it in the upper storey. For spring and 

 autumn feeding add a spoonful of acid to each quart 

 of syrup. As formic acid does not affect the flavour 

 of the honey, it can be used with perfect safety while 

 honey is being stored, and as a remedy it will be found 

 superior to either phenol or salicylic acid." 



Naphthol Beta, for which, as an antiseptic, we are 

 indebted to Dr. Lortet, is the most recently introduced, 

 and, being simple in application and inexpensive, it is 

 now the most generally used remedy. To facilitate 

 the use of Naphthol Beta the Editors of the British 

 Bee Journal have prepared packets containing suffi- 

 cient for a given quantity of food. The directions on 

 each packet are as follows :— " For every pound of 

 sugar used in making syrup or candy dissolve three
