The author reports on an outbreak of Nosema apis and recommends 

 the following treatment for the disease : — The first day, the queen bee 

 should be removed into the cell, or, if this is impracticable, either the 

 open brood must be removed or have mature, sealed brood added to 

 it sufficient to create an abundance of bee-nurses ; the bees must be 

 fed with a mixture consisting of 1| pints of boihng water, 15 grams 

 of Alexandria senna leaves, 1 grm. of cream of tartar, 1 tablespoonful 

 of tincture of cascarilla and 1 pint of honey (the water is poured over 

 the senna leaves and the cream of tartar, tightly closed and left in a 

 warm oven for from 12 to 24 hours, when the extract is decanted and 

 the remaining ingredients added to it) ; about j-| pint is allowed for 

 one family according to its strength. Feeding in the evening should 

 be done with 2 pints of boiled water, 1 teaspoonful of phosphoric acid 

 and I pint of honey. The second day, the bees must be removed in 

 the evening into the disinfecting hives and the size of the nest reduced 

 by removing the combs or those parts of them which contain traces of 

 the excreta ; if there are any drones, drone-traps must be put at the 

 entrance holes ; the queen bee should be left in the cell and the hive 

 fed on 1| pints of boiUng water, 1 grm. of cream of tartar, 2 grms. of 

 citric acid, 1 pint of honey. 1 tablespoonful of tincture of cascarilla 

 and 1 tablespoonful of spirits of camphor (the water is poured over 

 the cream of tartar and citric acid and allowed to cool down to about 

 110° F., when the honey is added and dissolved, then the cascarilla, and 

 after stirring, the spirits of camphor), |-| pint being the dose for one 

 family. The third day, feeding in the evening is done with the same 

 mixture as on the evening of the first day. The fourth day, feed in the 

 evening with a mixture consisting of \\ pints of boiling water, 2 grms. 

 of peppermint, 1 grm. of cream of tartar, 1 pint of honey, 1 tables- 

 poonful of tincture of cascarilla and 2 grms. of formic acid (the water is 

 poured over the peppermint and cream of tartar, tightly closed and put 

 into a hot oven for 12 to 24 hours, after which the extract is decanted, 

 the honey added and dissolved in it, and the other ingi'edients added 

 and stirred), \ - 1 pint being given to one family. The fifth day, feed in 

 the evening with the same mixture as in the evening of the first day. 

 The sixtJi day and onwards, pieces of camphor, of the size of a large 

 hazelnut, wrapped in gauze, are placed on the bottom of the hives and 

 renewed as they evaporate. The drones of diseased hives ought to be 

 caught and burned ; the hives must be well ventilated; in localities where 

 the disease is prevalent, the above treatment ought to be generally 

 applied as a preventive remedy in the first half of each month between 

 March and August, but it is not necessary to isolate the queen bee.
