146 A Modern Bee-Farm 
The so-called Isle of Wight disease (Infectious Paralysis) 
may be successfully treated by the definite methods of 
cure advocated by the Author. These are: (2) change 
of queens after an interval ; (4) the addition of healthy 
bees and brood to weak lots; (¢) feeding rapidly with 
properly medicated food, especially before winter ; (2) 
saturating the bees with efficiently medicated warm 
water ; (¢) the Author’s method of vaporising ; (7) dress- 
ing insides of hives with Veterinary Izal; (g) effectual 
ventilation ; (2) the use of practically immune bees.

BEE-PARALYSIS. 
Isle of Wight Disease ; Paralysis from Poison ; May 
Disease ; Dysentery ; Overheating ; Bad Ventilation. 
HE general cause of Paralysis in bees is to be found 
ris in the insects’ inability to breathe freely and fully, 
in consequence of the spiracles and air sacs becoming 
congested, and rendered useless for the time being, either by 
local poisoning, bad ventilation, acute dysentery, or, it may 
be, the action of some obscure disease germ * as in the case 
of infectious paralysis (Isle of Wight disease), with its 
consequent econstipation. ‘ 
It is all too frequently forgotten that the dark and 
* In one issue of the British Bee Fournal, the editor, describing 
acute dysentery, concluded this was the same as Isle of Wight 
disease. In a following issue, referring to Nosema apis, he again 
assured his readers this was the same thing as the Isle of Wight 
complaint. Nevertheless, in the said editorial it was shown that 
on the Continent bees are not apparently affected, and continue as 
vigorous as usual, when N. apis is present.
