THE PRIYATE BOOK OF USEFUL ALLOYS and Memo 

 randa for Goldsmiths, Jewellers, etc. By JAMES E. COLLINS 



This little book is compiled from, notes made by the Author from the 

 papers of one of the largest and most eminent Manufacturing Goldsmiths and 

 Jewellers in this country, and as the firm is now no longer in existence, and the 

 Author is at present engaged in some other undertaking, he now offers to the 

 public the benefit of his experience, and in so doing he begs to state that sill 

 the alloys, etc., given in these pages may be confidently relied on as being 

 thoroughly practicable. 



The Memoranda and Receipts throughout this book are also compiled 

 from practice, and will no doubt be found, useful to the practical jeweller.
