NATURE says:— "The firm of Leybold Nachfolger 

 in Cologne has recently issued a very complete and 

 interesting catalogue of physical apparatus and 

 fittings sold by them The book starts with a history 

 of the instruments made in Cologne during the last 

 century. In its second section we find an account 

 of the construction and fittings of various chemical 

 and physical institutions. After this follows the cata- 

 logue proper, filling some 800 large pages, profusely 

 illustrated and admirably arranged. The book will be 

 most useful to the teacher." (No. 1846, Vol. 71.) 



THE CATALOGUE WILL BE FORWARDED TO SCHOOLS 

 AND INSTITUTES ON APPLICATION.
