360. "Isle of Wight Disease."— This disease, of which the 

 cause and cure have still to be discovered, made its first appear- 

 ance in the Isle of Wight in 1504, and was described in the 

 Irish Bee Journal (igo6) by Mr. H. M. Cooper, Hon. Secretary 

 of the local Beekeepers' Association, who said that the symp- 

 toms of the disease were exactly as described in the Irish Bee 

 Guide under the heading of "Paralysis," (333-5). At that 

 time ninety per cent, of the stocks in the Island had perished.^ 



" In some cases several hundreds of 'bees are to be seen on the ground 

 near the hive, often crawling rapidly, but quite unable to fly, their abdomens 

 greatly distended and containing a large amount of ropy, yellowish-brown 

 matter. The .-itocks affected rapidly dwindle, and usually succumb in about 

 a month or six weeks, leaving their stores, and often a quantity of brood. 

 The queen appears to keep healthy and survives to the last. Although 

 re-queenmg and other remedies have often been tried, the results have always 

 been fatal." — Irish Bee Journal, June, 1906.
