It remained so at the end of October, although at this date it showed a propor- 

 tion of infected bfies 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. Glasgoiv, 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.
