SCIENCE GIVEN AT HAZELWOOD AND BRUCE CASTLE. Ill 



swered by the Teacher. More frequently, however, a work 

 has been selected by the Teacher, as a text-book for Class- 

 instruction, from which he has read to the Class, either 

 the whole, or suitable portions selected for the purpose ; in- 

 terspersing the reading with observations and corrections of 

 his 'own, and also frequently entering into detailed explana- 

 tions of the author's statements, when they were of too pro- 

 found or too complicated a nature, to be immediately apprehen- 

 sible by his pupils ; giving proper opportunities for receiving 

 questions from them, and occupying a portion of every lesson, 

 in ascertaining, by proposing questions himself, the degree of 

 progress made by each pupil in the particular subject before 

 him. The performance of Experiments, and the exhibition 

 of specimens and drawings have been combined, as much as 

 possible, with the oral instruction *. 



Those portions of " Harry and Lucy," (forming part of Mr. 

 and Miss Edge worth's " Early Lessons,") which bear upon 

 the truths of physical science, and are explained in that work 

 in the most familiar terms, have been adopted for the 



* It will readily be conceived that a very numerous series of pictorial 

 representations will be required, for the adequate illustration of the Course 

 of Instruction in the Physical Sciences, as stated in p. 8 1 . On this account the 

 foundation has been laid of a collection of prints and drawings, for the use of 

 this department. Drawing is one of the regular branches of instruction in 

 the Schools, and the Teacher has accordingly availed himself of the skill of 

 some of those pupils who have attained a degree of proficiency in that art, 

 in the preparation, under his superintendence, of large drawings and dia- 

 grams, expressly adapted to the illustration of his Lectures and lessons. 

 From their pencils, exerted chiefly "out of school hours," or during intervals 

 of comparative leisure, he has obtained copies, on a highly-enlarged scale, 

 of the illustrative engravings contained in some of the more important class- 

 books. These have been employed in the lessons given from those works, 

 and the pupils, having thus received explanations of the illustrations con- 

 tained in them, will be qualified to understand the engravings themselves, 

 when they meet with them in subsequent private perusal of the books. A 

 series of drawings, many of them greatly enlarged, has also been commenced, 

 of the instruments, machines, and natural objects described in some of those 

 class-books which are not illustrated by engravings. Most of the pictorial 

 representations employed in the Lectures have hitherto consisted, merely, 

 of extemporary diagrams, drawn with white chalk upon black boards, also 

 by some of the pupils ; but those with which the Courses on Vegetable and 

 Animal Chemistry were illustrated, formed the* commencement of a series 

 of permanent drawings for this purpose, to which additions have since been 

 made, consisting of sections of the instruments and apparatus employed in 

 the Lectures, &c. Large diagrams, in stong outline, of some of the Crystal- 

 line Forms which most frequently occur among minerals and salts, and co- 

 loured Geological sections, have also been prepared. 



Many of these drawings were exhibited in the Public Lecture on this De- 

 partment, delivered at Hazelwood, in October last, all the graphic illustra- 

 tions employed in which, with the exception of the Transparency repre- 

 senting the Hylesinus Destructor, were from the pencils of the pupils.
