higher plants is likely to be of the greatest value. It will 

 be seen, however, that the aim is to lead the student on 

 from the simple to the complex by natural stages, and in 

 such a way that each successive step depends upon and 

 is, to some extent a review of all the preceding. 



Drawing constitutes an important feature of the course, 

 and each student is expected to make a complete series of 

 drawings of at least one plant in each of the groups studied. 

 This not only fixes the main facts securely, but leads to 

 greater accuracy of work, and a more critical judgment, 

 while it also promotes facility in drawing, a most essential 

 adjunct to all biological work.

 1. — GoTHITE. 



In a report on the Iron Ores of Canada, published in 18*74, 

 the writer called attention to the occurrence of gothite in 

 Nova Scotia. It was found by him associated with the 

 hematite and limonite of Clifton (Old Barns), and also 

 with black oxide of manganese, calcite, barite, &c, in 

 veins cutting the Lower Carboniferous limestones of 

 Black Eock, near the mouth of the Shubenacadie Eiver. 

 In some cases it appears as a velvety coating upon 

 hematite, calcite, or other minerals, but the finest specimens 

 obtained consisted of beautiful radiating needles with 

 adamantine lustre (nadel-eisenstein or needle iron-ore), the 

 needles occassional ly being capped with rhombohedral 

 crystals of calcite. Minute single crystals of the gothite 

 were also observed.
