 of Sir H. Davy, by which he ascertained the high temperature 

 necessary for the inflammation of this gas and the consequent 

 means 3 preventing the inflammation, when the gas has its 

 temperature lowered^ passing through any coo ling mech urn a 

 circumstance which eventually led to the ™™^™f en ™ 

 safety-lamp in its present form. It appears to have been as 

 SSl inX mines of Flanders as in those of Engknd since no 

 accident of any kind has occurred there since it has been 

 Spied, nor ha/any inconvenience or difficulty been experienced 

 with respect to it. The pamphlet can scarcely be said to con- 

 tain an/information that is new to us in this country ,butit 

 must be regarded a valuable document, in as much as it affords 

 T ndepenaent evidence in favour of the value of the -^»g

XII. Infirmary for Diseases of the Eye. 

 Sir William Adams having been nonunated by his ' Majes^s 

 government to superintend that part of York R ospi^^^ 

 which has been appropriated to the reception of the bl md gen 

 sioners belonging to the army, navy, and artillery, feels it a duty 

 to Uv open to the profession at large his new modes of treating 

 Xem This duty is suggested as well by the pecular confidence 

 5 has been reposed in him, as by the high sanction thus 

 Conferred upon his improvements in ophthalmic surgery He, 

 therefore freely invites all medical practitioners, and students, 

 who are interested in the advancement of this branch of surgery, 



to attend h" operations at J^^f^f^SS?^ 

 vemence, will be performed in future on Tuesday, and May,, 

 between the hours of seven and nine m the morning. 



To remove all doubt, or misconception, with regard to S r 

 William Adams's practice, he proposes, on each of the.e day., 

 to o-ive a description of the nature of one of the diseases to oe 

 operated upon-the general modes of performing the operation 

 S ^s peculiar mode^and his reasons for deviating from the usual 

 nractice where such deviation has been found necessary. 

 P The recm^s kept of each case, from the patient's admission 

 into tie Hospital to his final discharge, will be open at the periods 

 ilreadv mentioned, for the inspection of such gentlemen as 

 a=; so thatthe'profession will be enabled fair y to .ap^rec-te 

 the character of the new as compared with the old modes ot 

 practice.
