DETONATING BALLS. 



These balls, which have for some time been exhibited at Lec- 

 tures as a chemical experiment, are now sold in some shops in 

 London. V/e are sorry that they should thus be put into th« 

 hands of children and foolish people. They are formed by in- 

 closing in little glass bulbs about a quarter of a grain of fulmi- 

 nating silver, and then covering the bulb with thin paper pasted 

 all over it to secure the ori.uce. Children by putting them into 

 their mouths may be much injnred by their explosion — received 

 into the stomach thev would cause death. 



SCHOOL OF PHYSIC IN IRRLAND. 



The Education of Medical ."Students is committed to six Pro- 

 fressors. Three of these, viz. the Professors of Anatomy, Clic- 

 luistrv, and Lotanv, are on the foundation of Trinity College, 

 and are called the University Professors. Tlie other three, viz. 

 the Professors of tlie Institutes of Medicine, of the Practice of 

 Medicine, and of Materia Medica, are on Sir Patrick Dun's 

 foundation, and are called the King's Professors. 



The Lectures on the above subjects commence on the first 

 Monday in November, and terminate on the last day of April 

 in the succeeding year. Dis-rections and Anatomical Demonstra- 

 tions begin w^ith December, and end early in tiie follov, ing April. 

 The Lect\;rps on Botany commence on the first Monday in May, 

 and continu.e to the end of July. 



The Terms of attendance on each Course of Lectures are four 

 guineas, — The Terms for Dissections and Anatomical Demon- 

 strations are six guineas ; for which also, half of a subject for 

 tlie Muscles, and half of another with the Bloodvessels injected, 

 are furnished. The Student is likewise at hberty to dissect an v 

 number of subjects he may procure at lis own expense. For 

 the use of the Dissecting-room daring the Season, without Sub- 

 jects being furnished, and for tlic Demonstrations, five guineas 

 are paid ; or for the Demonstrations alone, four guineas. 



The Students in Botany have the use of one extensive Botanic 

 Garden, and access to another in the immediate vicinity of 

 Dublin. The opportunities of acquiring a knowledge of other 

 branches of Natural History are also very considerable, especially 

 of Mineralogy, bv means of the valuable collection of Leske which 

 is open to the public. 



Tlie Clinical Hospital, belonging to the Scliool of Physic, i« 

 supported bv a large endowment of the late Sir Patrick Dun.
