fROCEEDlNGS OP THE SOCIETY. 261 



sending you this because this man knew nothing of ]\Iicroscope work 

 beyond what he had done in the medical schools, and, what is more 

 important, he has not what may be called good sight for instrumental 

 work. He is so troubled with muscse that only the lowest power eye- 

 pieces can be used. 



" This case proves the ease with which the flagella (or whatever 

 these appendages of the tubercle bacillus are) can be seen." 



Dr. Hebb also read an abstract from a letter from Major Sampson, 

 describing an observation made in Southern Nigeria, as follows : " A 

 curious case came under my notice the other day (I have not seen it in 

 any book). A thick living arch of travelling ants across a sunny road, 

 and in the centre hundreds of pupa3 being carried along in the shade 

 thus caused ! ! This is the more wonderful because the African ant, as 

 a rule, cannot stand the sun at all." 



The President said no doubt many of those who were present had 

 seen the very ])eautiful slides which had been sent up by Mr. Flatters 

 for exhibition that evening — some of which were exceptionally good. 

 He was sure they would all unite in passing a very hearty vote of thanks 

 to Mr. Flatters for his kindness, and would also give their thanks to 

 Messrs. Beck for the loan of the Microscopes under which many of these 

 slides were shown. 



The thanks of the Society were unanimously voted accordingly.
