pared for the purpose by Mr. Perrin. A small pipe having been introduced into 

 the pulmonary artery, and tied round, it was fixed to a syringe, filled with the 

 blue fluid, which was then forced into the artery by the pressure of the hand, 

 and, passing thence into the smaller vessels throughout the body, soon forced 

 out the natural fluids of which it took the place. In about two minutes the 

 feet of the animal begun to turn blue, showing how completely the fluid had 

 pervaded the whole system ; and the lung was then removed, and handed round 

 the room for the inspection of the members, who were thus enabled to see how 

 completely successful the operation had been. A frog was next experimented 

 upon, and the injection of the lung was again perfectly successful ; after which 

 a second rat was injected, and showed very clearly the complete manner in 

 which the injecting fluid had filled the smaller vessels of the ears, eyes, and 

 tongue. Injected specimens of various kinds— some injected with several 

 colours — were exhibited by means of portable microscopes, which were passed 

 round amongst the members ; and after giving a few further practical hints as 

 to cleanliness, pressure, cleansing in cases of extravasation, &c. Dr. Beale con- 

 cluded his remarks, which had been listened to throughout with the greatest 

 interest and attention, amidst a hearty outburst of prolonged applause. 



Dr. R. Braithwaite said that he felt he had now a duty to perform, in which 

 all would join, namely, that of proposing a vote of thanks to Dr. Beale for what 

 he had brought before them that evening. 



Mr. T. C. White seconded the motion, and expressed his personal thanks to 

 the president for his kindness in coming forward in the way he had done. The 

 vote of thanks was then put to the meeting and carried by acclamation. 



The President having briefly responded, the proceedings terminated with a 

 conversazione, at which the following objects were exhibited —
