^4th August. Visited Cullerlie, K's Apiary.— Isle of Wight disease 

 prevalent in most stocks. No. 10 has got it. But the Italians, Nos. 25 and 

 18, are both going on well with no signs. Hybrids also are well, and these 

 have swarmed lately. This swarm has settled in the top of a hive at Wood- 

 side which has got Isle of Wight disease very badly. I saw both stocks 

 working (above and below) from the same hive. Took sample from No. 10. 

 Eesult — failure to find Nosema. 



E , Finnercy. —Jia.s Isle of Wight disease in most of his stocks. Took 



a sample from the worst, but did not find Nosema spores. Examined all K's 

 sample, also H's. All had congested colons with pollen in a pasty condition. 

 Most had chyle-stomachs, purplish ; some were quite dark. 



Main Features of Deeside Epizootic. 



This report deals with twenty-three apiaries extending from Culter, 

 near Aberdeen, to Dinnet, a stretch of about 30 miles along the Dee 

 valley, and covering 3 or 4 miles on either side. 



I. The epizootic was observed first in 1913, in particular at Culter 

 and Dinnet, and in stocks introduced from the South of England. 

 In the Culter case one year at least elapsed between the time of 

 arrival and the commencement of the outbreak. The disease is 

 still prevalent in this district. 



II. Within the area there has been a very considerable amount of 

 destruction of bees and appliances, of disinfecting generally, and 

 also of experimenting by the bee-keepers with advertised remedies. 

 All these efforts have failed to cure the disease or to affect 

 recognisably its continuance. 



III. There are instances of stocks " passed over '' within apiaries, though 

 in close proximity to sick stocks. In this area at least one example 

 is known of a stock prospering in a non-disinfected hive in which 

 a stock had died out of the disease. 



IV. Bees, in a number of instances, were sent by bee-keepers to the 

 editors of the British Bee Journal, and were reported to be suffer- 

 ing from Isle of Wight disease. We have been unable to find 

 Nosema in the bees of Deeside generally.
