DR. MATTHEWS ON A NEW METHOD OF ILLUMINATION. 



intelligent maker can see almost at a glance how it can be effected. 

 I have hitherto used direct lamp light only ; but it is quite easy 

 to adapt a prism or mirror for the convenience of those who prefer 

 daylight. I need scarcely say that I shall be happy to give my 

 plans for either form to those who may wish it. 



I will not occupy your time any further now, for I fear that I 

 have trespassed too much on your patience already. I had much 

 more to say, but think that I may well leave it for a future paper, 

 if the subject prove interesting to you. 



Most of those around me know my profession, and may easily 

 imagine, therefore, how little time I have at my disposal for carry- 

 ing out investigations which require an uninterrupted leisure. If, 

 however, what I have said shall induce others who are not similarly 

 fettered to take up the subject, but with greater skill, knowledge, 

 and experience than I can pretend to — and I see many such before 

 me — my purpose in jotting down these observations will have been 

 answered, and I shall leave this place to-night contented and 

 happy.
