142 PEOCEEDINGS OF THE SOCIETY. 



which had drawn them up with the blood they had sucked. Some 

 successful attempts at instantaneous photomicrography of the Amoebfe 

 were also shown. As illustrating photomicrography with extremely 

 high powers, a series of slides of the usual test objects was shown, such 

 as Podura scale, up to x 2500, Pleurosigma angulatum up to x 2200, and 

 Amphipleura pellucida up to x 4250 — the highest ever taken direct by 

 the lecturer with a lens lately made by Powell. The finest and most 

 interesting pictures shown in this section were undoubtedly those of 

 bacteria which had been stained and photographed through coloured 

 screens, the use of which was duly explained. These included the 

 specific organisms of diphtheria, bubonic plague, cholera tubercle, and 

 typhoid. The action of phagocytosis was also admirably shown. 



The lecturer remarked that the 1/8 apochr. N.A. 1*40 by Zeiss was,, 

 he believed, the finest lens in the world; other makers might equal it,, 

 but none, in his opinion, had ever surpassed it. Although he had shown 

 such fine results with Powell's lenses, these two great firms held the 

 apcchromatic world under their thumbs, and merited the warmest thanks 

 of all microscopists. Notwithstanding this, he had shown some very 

 good work that could be done with low powers by Beck, and especially 

 by the photo-corrected series by Wray. 



Owing to the lateness of the hour at which the exhibition concluded^ 

 it was not found possible to discuss the many interesting points which 

 had arisen, but the President tendered on behalf of the Society their 

 indebtedness to Dr. Spitta for the very beautiful exhibition he had given 

 them, and also for his extremely interesting explanations. 



A hearty vote of thanks to Dr. Spitta was formally put to the Meeting 

 by the President and carried by acclamation. 



Dr. Hebb having been obliged to leave the meeting at an earlier 

 period of the evening, Mr. Vezey on his behalf reminded the Fellows

 for these were as follows : —

The Council had also appointed Mr. J. M. Allen as Auditor of the

 Fellows.
