June 8.— Mr. John Brent, Jiin. delivered a Lecture on 

 Pneumatics. After a few prefatory remarks on the revival 

 of science in the fourteenth and fifteenth centuries, he pro- 

 ceeded to give a brief history of the originof the principles of 

 Pneumatics — referring to the doctrines of the school of Aris- 

 totle, and the subsequent hostility that the followers of that 

 school manifested towards the brilliant discoveries of Galileo, 

 Pascal, Toricelli, and others of the Literati of the time, 

 who advocated the doctrine of atmospheric pressure. The in- 

 vention of the first air pump, and the improvements or additions 

 of most importance upon that instrument came next in review. 

 After describing the different properties of air, its weight, elas- 

 ticity, Sic., together with the interesting phenomena attendant 

 on these properties, the Lecturer concluded by referring the 

 higher principles of Pneumatics to their practical elucidation 

 in the doctrine of projectiles and the arts of gunnery and 

 navigation. 



June 15, — The Rev. J. Quin delivered a Lecture on the 

 utility of general information, and the advantages of culti- 

 vating the understanding. After shewing that the most 

 valuable part of humanity consisted in intellectual qualifica- 

 tions, the Lecturer in a logical manner proved the utter 

 absurdity of the position that knowledge was not intended 

 for every one, and convincingly proved that the less know- 

 ledge a man possessed, the less utility he must be to his 

 family, to society, and to his country. He pointed out the 

 grand divisions of human knowledge; and concluded by 

 proving that considerable information was requisite for the 

 perfect understanding of moral Philosophy, and which when 

 comprehended would operate more in favor of happiness to 

 the individual, than any other study. 



June 22. — Mr. W. J. Cooper delivered a Lecture on 

 Vegetable Physiology, in which he developed the difTcrent 

 chemical changes in the Vegetable World, and described the 

 nature and properties of the various Earths which constitute 

 the soil proper for the growth of Vegetables, as well as the 

 external agents, air, water, light, and hcnit. Several Dia- 

 grams were produced to illustrate the different layers of the 

 trunk of the Tree, as also the circulation of the sap, and 

 change produced upon it in its progress through the leaves. 



June 29. — Mr. Hunt delivered a Lecture on the Properties 

 of MattcT. He commenced l)y urging upon all the students 

 of science the indispensable importance of Ix'ing well grounded 

 in the knowledge of those phenomena of matter which form 

 the basis of all the scien<'es ; describing the laws which re- 

 gulatf! ihe movements and constitution of the material world, 

 us standing in the same relation to the practical sciences as
