This stock was allowed to die out naturally, but the hive had been removed 
to another site, and the original stance disinfected. A small remnant was 
found stiff and motionless on one comb, on 29th February 1912. Thorough 
disinfection of the site was effected by spraying crude carbolic acid, of such 
strength that the worms came up and died, and the grass also was killed. 
All inside fittings of the hive were burned, paraftin was also poured on the 
hive site, and burned off. 
Fourth Attack. Stock D4.—This stock, a strong one, crowded with bees . 
and brood, along with two others, came from Exeter on 21st May 1912, 
where as yet the disease was unknown. It was placed on the stance 
of D1, referred to above. Isle of Wight disease symptoms appeared on 
28th May, exactly one week after the arrival of the stock upon the island, 
and large numbers of crawling bees were observed in front of this hive on 
every fine day. On 8th June, all the stores were exhausted and all the brood 
was dead. Syrup was supplied, and the queen laid more eggs. On the 
15th June there were still numerous bees, eggs, a few grubs, and food. At 
this date samples were sent to Cambridge, and Dr Graham-Smith’s report 
upon them is as follows :— 
“The bees you sent all arrived dead. No spores were found by 
microscopic examination, and it was impossible to say for certain whether 
young stages of Nosema were present or not. I tried to infect some healthy 
bees, but this experiment has turned out negative. 2/7/12.” 
On the 17th bees were lying about in large numbers on the aes 
board and on the grass around, and dying off rapidly. 
On the 11th July, the remaining bees, along with queen, were sent to 
Dr Graham-Smith, who kept them for some time. His report regarding 
them is :— 
“The bees you sent have been doing moderately well, and nothing very 
special has yet been found in those which have died.” 
This must mean that Nosema was not found, yet the behaviour of the 
bees, and the high mortality clearly indicated Isle of Wight disease. 
In the case of this stock no disinfecting measures were adopted, nor in 
any subsequent instance in the Nicolson Apiary, Stornoway. 
Fifth Attack. One Stock (K.M.).—This stock arrived in Stornoway from 
the South of England on 31st May 1912. Its ten combs were crowded on 
11th June and a super was added. The super was quite full of bees on 
22nd June, and some sections were ready for sealing on 13th July. Latera
