PREFACE 



In this second report the record of the proceedings of the Harrow 

 School Scientific Society is continued to the end of the Summer 

 Term, 1867. Its publication has from various causes been too long 

 delayed, but it is hoped that the papers contained in it will not 

 thereby have lost their interest for the members and friends of the 

 Society and of the School, and that a third report bringing forward 

 the record nearly up to the current date will appear after no long 

 interval. It will, we trust, be felt that the Society has by this, as 

 by the former, report "justified its existence," and made good its 

 claims for wider and more active support from present members of 

 'the School. It is probable that some change in the constitution of 

 I the Society will shortly be made, by which larger numbers will 

 'become admissible to our meetings, in the hope that by extending its 

 influence over a wider area it may become, what we believe it 

 already to be in a considerable degree, an important integral part of 

 the intellectual life of Harrow School.
