labour." So says Mr. Orford in his preface. He 

 has, however, set himself to lessen that loss of 

 time, and maybe of temper also, by setting forth 

 in simple manner the best means of proceeding 

 when one desires to make one's own 

 lenses. Even for those who do not 

 care to expend time on such work, 

 this book will be useful in giving a 

 better understanding of the place of 

 lenses in optics, and will explain the 

 occasional great cost of such as they 

 may require to purchase.

Every one who has had the pleasure 

 of meeting the enthusiastic author of 

 this work will be glad to hear that 

 another of his handbooks has been 

 printed by the Government of Ontario. 

 Its intention is to place before teachers 

 and others in Canada, a concise and 

 fully illustrated account of the Indian 

 people of North America, from an 

 ethnological point of view. In his 

 first chapter entitled "Whence came 

 the Indians," Mr. Boyle points out 

 the probability of frequent enforced 

 vogages to America by stress of 

 weather, from Asia on the one side 

 and Europe on the other, in those 

 dark ages long prehistoric to the 

 Columbian period. Certain it is that 

 the earliest remains of human civiliza- 

 tion found on the American continent 

 of the stone age, are in many instances 

 almost identical with the types of 

 worked flints of the old world. The 

 numerous illustrations are for the 

 most part, if not entirely, new, and 

 are taken from the provincial collec- 

 tion in the Museum at the Canadian 

 Institute, at Toronto. J. T. C.
