object they have determined to throw open, without additional charge, the 

 practice of the several institutions to which they are respectively attached. 

 We have opened to you a chest infirmary, an eye institution, and portions 

 of the practice of seven dispensaries. At these institutions, eleven clinical 

 clerks will be appointed from this school. At these charities, you will see 

 diseases as you will have to treat them in after-life : you will see them 

 under the same circumstances of position and state, and you will have 

 most ample opportunities of making yourselves acquainted with diseases 

 in all their multifarious forms. 



I trust you will excuse me if I say a few words upon the relation which 

 we are desirous should exist between the teachers and pupils. We are 

 one and all desirous that free intercourse and communication should con- 

 tinually take place between us. We wish you to regard us as students 

 further advanced in that knowledge, the end of which we can never 

 attain. Whatever you would ask of a friend, ask of us, as your teachers, 

 and nothing will please us so much as continually to contribute to 

 your welfare. 



You are about to enter, gentlemen, upon the study of the most 

 exalted profession. Every moment of your life will be spent in the 

 study and observation of nature. The most intimate structure of the 

 human body will be exposed to your view, and the innermost recesses of 

 the human mind will be revealed to you. Every moment of your life will 

 be spent in doing good, and contributing to the happiness and welfare of 

 your fellow-creatures ; day by day you will receive the praises and heart- 

 felt thanks of gratitude for your aid in the time of danger and disease. 

 Let me not deceive you, gentlemen ; do not think you will attain eminence 

 without the most incessant labour and the most unremitting attention ; 

 and you will find, with all your exertion, your utter inability to master the 

 subject you have taken in hand. Delighted with every step you make, you 

 will, in the language of the Psalmist, exclaim, " Such knowledge is too 

 wonderf ul and. excellent for me, I cannot attain unto it." 



[NOTE. The lecture throughout was profusely illustrated with 

 specimens of the power of man, and the room presented generally an 

 imposing appearance, from a display of beautiful examples of the novelties 

 of science.]

ON THE DETECTION OF NEEDLES, ETC., IN THE HUMAN 

 BODY. Lecture delivered at the Aldersgate School of Medicine, 

 December 9th, 1844. 



WHEN the foreign body, retained in the wound, is either iron or steel, 

 we have means by which we may readily and effectually determine its 

 presence. Portions of steel are particularly liable to be introduced into 

 the body, in the shape of needles, or as parts of cutting instruments ; and,
