No. XXII.] APPENDIX. '299 



" After being married, lie is like an Ass (that is, bui-thened). 



" Having got children, lie must find food for them ; and is therefore as 

 impudent as a Dog. 



" Grown old, he gets like a Monkey, — but (this is) only the ignorant 

 man : whereas of the wise man Scripture says, ' King David was old ' 

 (1 Kings i. 2). Old, but still a king." * 



In the remarks which I have made this day, I would wish you clearly to 

 understand that I do not expect all of you are to become professed chemists, 

 naturalists, or botanists ; nor in fact necessarily professors of any other 

 branch of natural knowledge. I have particularly desired to call your 

 attention to the value of natural knowledge to all classes of society. You 

 should esteem natural knowledge as indispensable to every gentleman; and 

 I feel sure that all the points which I have reviewed for your consideration 

 should not be neglected by anyone aspiring to the title of an educated 

 Englishman. 



I doubt not that there are very few of you who would not greatly 

 prefer these lectures to your ordinary school exercises. Tou must not, 

 however, neglect the tediousness of books for the pleasures of lectures. 

 Follow the study of languages, arithmetic, and of mathematics at school as 

 the most valuable aids to the understanding of natural knowledge; and 

 prosecute natural science as a guide for the conduct of your own affairs. 

 The study of Nature confers on you pleasure, honour, power, the means of 

 procuring wealth, of benefiting your fellow-creatures, and leads you to the 

 contemplation of the Sourca of All Good. 



The London Institution has given you great opportunities of instruc- 

 tion ; and if my discourse should determine any of you rightly to take 

 advantage of the benefits now offered, the words of my heartfelt appeal to 

 study Nature with earnestness and attention, will be engraven on your 

 minds to the latest day of your lives ; and you wUl rejoice that you have 

 been this day present at the London Institution.

ON THE NEW BANK OF ENGLAND NOTE, AND THE 

 SUBSTITUTION OF SURFACE-PRINTING FROM ELEC- 

 TROTYPES FOR COPPER-PLATE PRINTING. By Alfked 

 Smeb, F.R.S., Surgeon to the Bank of England. 1854. 



I FEEli some delicacy in appearing before the Society of Arts upon a 

 matter of so much importance to the commercial community as the print- 

 ing of the Bank of England notes ; nevertheless, from the part which I 

 have played in this matter, I trust the members of the Society wiU not 

 think that I am exceeding my duty in bringing the matter before them. 



In the month of November 1851, I had the honour of presenting a 

 report to Mr. Hankey, the Governor of the Bank of England at that
