140 MEETING OF THE BRITISH ASSOCIATION 



The second paper was by Dr. Houston, descriptive of a Twin 

 Foetus born without Brain, Heart, Lungs, or Liver. 



The third and last paper which occupied the attention of the sec- 

 tion this day, was one by R. Carmichael, Esq. on Tubercles. The 

 reading of this paper, many of the propositions of which were illus- 

 trated by preparations in a high state of preservation, occupied one 

 hour and a quarter, and commanded much attention. 



Wednesday. — The business of the section commenced this 

 morning by reading — 1st. A report of the Dublin committee ap- 

 pointed by the British Association, on the Motion and Sounds of 

 the Heart, read by Dr. Macartney. 2nd. A report of the London 

 committee on the same subject, read by Dr. Clandining. 



The third subject introduced was on the Gyration of the Heart, 

 by A. P. A. Greeves, Fellow of the Royal Colleges of Surgeons of 

 Edinburgh and London, and one of the Honorary Surgeons of the 

 Nottingham Dispensary. 



A paper on the Polarization of Light observed in the Crystalline 

 Lens, by Dr. Brewster, was read by the president ; as was also a 

 letter from the same gentleman on the subject of cataract, which, if 

 resisted in its early stages, the Doctor believed might be overcome. 

 This disease, which generally manifested itself between the ages of 

 forty and sixty, when persons began to require spectacles, the Doc- 

 tor gave a recipe for detecting, which he had done in his own case ; 

 and though perhaps induced by an impaired state of health, yet, by 

 attention to diet and regimen, and taking care not to study by 

 night, he found, in about eight months, he had been cured. If the 

 affection had not been checked in time, he entertained no doubt it 

 would have ended in cataract. 



The last paper read was one possessing great interest — " On 

 Absorption," by Dr. Carson, of Liverpool. 



Thursday. — The first paper read was by Dr. Hodgkin, on the 

 Connection between the Veins and Absorbents. Dr. Reid then 

 read his paper entitled " A short Exposition of the Functions of the

 containing some particulars on the Anatomy of the Fifth Nerve. 



Dr. Macartney exhibited to the members a portable probang. Dr. 

 M. also read two short papers : one an account of the Organs of 

 Voice in the New Holland Ostrich, and the other on the Structure 

 of the Teeth. The last paper was by Mr. Walker, on the Nerves 

 and Muscles of the Eye-ball. 



Friday. — The first paper read was entitled " Observations on the 

 Pathological Condition of the Bones in Chronic Rheumatism ;" and 

 " On the Condition of the new Circulatory Channels in a case of 

 Double Popliteal Aneurism," by Mr. Adams. 



The third paper read was a report on " Fracture of the Neck of 

 the Thigh Bone," by Dr. Evanson. 



All of the above papers seemed to derive an interest from Mr. 

 Hetling's, " On a new Instrument for the removal of the Ligature
