It remained so at the end of October, although at this date it showed a propor- 
tion of infected bees of about 27 per cent. (33 bees, 9 infected). 
At the present time (30th October) this stock is strong in numbers, without 
visible signs of disease. The owner has united it with one half of the swarm. 
No. Glasgow, P. — This stock at the beginning of June was strong and working 
well. The bees covered ten frames, six of which were very well filled with brood. 
Brood was also present upon the other four and there were plenty of stores. The 
stock swarmed at this date but the swarm, secured with difficulty and with a loss 
of bees, was returned to the parent stock. On 17th June a sample of thirty-four 
bees was examined, and of these three were found infected with Tarsonemus. 
There were no external signs of disease and matters appeared normal with the 
stock. During the next three months the owner paid little attention to it, and 
in September the bees were reduced to four frames with brood and were without 
food. None of the usual signs of Isle of Wight disease had ever been seen about 
the stock, which was now being fed. A sample of twenty-nine bees was taken on 
7th September, and of these two only were infected. This shows a slight decrease 
as judged by the samples. A later sample supplied at the end of October, how- 
ever, showed an increase in proportion of infected bees. The stock as a whole does 
not appear affected by the presence of the parasite, but it is not particularly strong 
in numbers. 
No. 62. — Early in May of this year a nucleus of three frames of bees with queen 
and brood was obtained. 
On 27th May fifteen bees, and again on 3rd June four bees, were examined for 
Tarsonemus, with a negative result. The bees were standing in an infected apiary 
and at this time were working well and rapidly increasing in numbers. 
On 14th June twenty -five bees were examined, and of these twenty-two were 
found clear of the parasite ; of the remaining three, two contained several 
parasites and one a single adult female. The bees multiplied rapidly and swarmed 
twice in the course of the summer. 
On 15 th September thirty -three bees were examined, and of these nineteen 
proved infected. 
At this date there were no signs of disease as far as behaviour of the bees 
was concerned. The numbers were well maintained and the stores sufficient. 
At the end of October, forty bees were taken and all except three were found 
infected. The pathological features were not marked. The stock is apparently in 
a strong condition as regards numbers at this date. 
No. 60. — On 20th May a small lot of bees covering three frames was obtained, 
which on examination was found to be harbouring the parasite Nosema apis. 
Apart from this there were no external signs of disease about the stock, and it 
built up moderately well. By 2nd August the bees covered over nine frames, with 
brood upon seven. The season was poor and stores were short.
