SCIENTIFIC INTELLIGENCE, AND NOTICES OF SUBJECTS 

 CONNECTED WITH SCIENCE. 



I. Lectures. 



Mrs. Lowry is about to recommence her Lectures on 

 Mineralogy. 



Mr. Guthrie, Deputy Inspector of Military Hospitals, will 

 commence his Spring Course of Lectures on Surgery, on Mon- 

 day, Jan. 19, at five minutes past eight in the evening, in the. 

 waiting room of the Royal Wesminster Infirmary for Diseases of 

 the Eye, Marylebone-street, Piccadilly. To be continued on 

 Mondays, Wednesdays, and Fridays. 



Mr. Thomas Bell, F.L.S. will commence his Lectures on the 

 Structure and Diseases of the Teeth, &c. at Guy's Hospital, on 

 Friday, Jan. 9, at half-past five o'clock. 



II. Safety Lamp for Coal-Mi nes. 



A publication has been forwarded to the Editors, eutitled, a 

 " Report upon the Claims of Mr. Geo. Stephenson relative to 

 the Invention of his Safety Lamp, by the Committee appointed 

 at a Meeting holden in Newcastle, on Nov. 1, 1817." The 

 Editors of the Annals, not choosing to take any part in the 

 controversy between the friends of Sir H. Davy and of Mr. 

 Stephenson, have not inserted the Report of a Committee of Sir 

 H. Davy's friends assembled at Sir Joseph Banks's ; and for the 

 same reason shall abstain at present from noticing the proceed- 

 ings of Mr. Stephenson's friends. At some future time, how- 

 ever, they mean to take up the subject, and to give, with all the 

 impartiality in their power, a history of the experiments insti- 

 tuted, and of the machines invented, for the purpose of prevent- 

 ing explosions in coal-mines. 



III. Fluor Spar in Scolland. 



Fluor spar, although abundant in England, is one of the 

 rarest simple minerals found in Scotland. Hitherto it has been 

 met with but in two places : at Monaltree, in Aberdeenshire, 

 where it forms one of the constituents of a galena vein in gra- 

 nite ; and in the remote island of Papa-Stour, one of the Shet- 

 lands, in vesicular cavities in amygdaloid, associated with chal- 

 cedony, calcareous spar, and heavy spar. A few months ago 

 Professor Jameson, during his investigation of the mineralogy 

 of Renfrewshire) again met with this rare substance, near the 

 village of Gourock, in vesicular cavities in porphyry. 



IV. Chromate of Iron in Slid land. 

 Dr. Hibbert, who lately visited the Shetland Islands, with the
