Lancet :“This book will be especially valuable to the student of chemistry, whilst to the lecture a sistant it is simply a sine qua non. The expriments are all ad nirably described and of the kind whi h are calculated nt only to excite the siudent's inierest but to clearly point out to him the lessons which they are intended to convey."

Sir H. E. Roscoe, in Nature :“ The very description of a good lecture experiment to one who had for thirty years always enjoyed performing an old one, and was overjoyed in bring.ng out a new ne, is something akin to that of the old war-hurse when he scents the battle frum afar. And both Mr. Newth's experiments and his d-scriptions are good; so I think that not only the nvices of the profession but the old hands will read this book--the first with profit with a view to what they will do, and the secind with pleasure in rec llecting what they have done. ... All the ordinary and many fthe extraordinary experiments detailed in the book may be carried out with limle cost and without great trouble : indeed, st of them may be made by the veriest tyro provided he stick to the letter of the description ... 01 good experimen's 'there is no end' (Mr. Newth describes 625 for the non-metals alone) whilst of a review of a book in NATURE there must be a speedy end, and I will end by advising all those who like to see and to show god experiments to get Mr. Newth's book."
