which bad been given in tbo two papers beforo them, were certainly 

 very full and valuable, and he very much regretted tbat, owing to the 

 lateness of the bour, it was impossible to afford time for their dis- 

 cussion. Tbo authors, however, were to be much congratulated on 

 tbe lucidity of their explanations tbat evening. 



Dr. E. M. Orookshank gave a resume of his paper on the Surra 

 parasite, under the title of " Flagellated Protozoa in the Blood of 

 diseased and apparently bealtby Animals," which he illustrated by 

 drawings, photographs, and specimens exhibited under tbe Microscopo 

 (supra, p. 913). 



Tbe President regretted that time did not permit them to give a 

 proper discussion of this subject, which was evidently of great interest 

 and practical importance, and Prof. Bell referred to previous papers 

 of Biitschli. 



Dr. Crookshank said that it was rather a disadvantage to discuss 

 the subject of a papor only parts of which had been read ; but when tho 

 paper was before tbem in extenso, they would see that be had not 

 overlooked what Biitschli bad said. At that late bour of tbe evening
