16th June——A fine day. Bees appeared normal. No. 2 looks like 
swarming. No crawling bees seen. 
21st June.—A dull, rather cold day. Bees were clustering on the ground 
near all three hives in small groups. No. 2 appeared to be the only normal 
stock, and was strong. The bees from No. 1 and No. 3, both inside and 
outside the hives, appeared weak and dormant and unable to sting. There 
were very few dislocated wings. The abdomens and general appearance of 
the bees, with a few exceptions, seemed normal. It is doubtful whether 
any bees from No. 2 were clustering, although there were clusters under that — 
hive. 
22nd June.—A fine day. The symptoms just as previous day. No. l 
and No. 3 stocks were destroyed and the hives disinfected. 
24th June—No 2 was working well and looked like swarming. The 
ground was limed. 
26th June.—No. 2 working well. 
29th June.—Swarm came off, but got away and was lost. 
9th July.—Bees working well, but some few drones observed crawling. 
15th August.—No. 2 working well and seems strong. Supers nearly full. 3 
This stock died out during the winter 1914-1915. All stocks belonging 
to three bee-keepers, who were near neighbours of N, were lost also. 
0.—O’s apiary was 2 miles north of N. O had six stocks, and in July 
1914 these were all found to be suffering from Isle of Wight disease. Only 
one stock survived till 1915, and that eventually died out. 
Several cases were reported at Raemoir in 1914 which were not verified 
as the stocks had been destroyed before notice was received. 
In 1915, there were two outbreaks, three-quarters of a mile distant from 
each other, at this place. 
P.—P had five stocks in good hives, clean and well kept. The stocks 
were all strong. All appeared healthy in June 1915, but in July Isle of 
Wight disease was very marked. Numerous bees were crawling on the 
ground and clustering; others were climbing up grass and leaves; many 
had dislocated wings and distended abdomens. In those examined the colon 
was very much enlarged and clogged. There were many dead lying about. 
Three of the hives contained parent stocks, while the other two held 
swarms. The parent stocks seemed to be more severely attacked. P 
destroyed all his bees at the end of July and cleaned and disinfected his 
hives and appliances. 
(.—Q’s apiary was not so well kept, and his stocks were weak, con- 
sequently the outbreak did not appear so marked, and the disease lingered 
on for a long time. I have frequently noticed that when a really strong
