462 Notices respecting Neiv Booh. 



genious and learned editor Dr. C. Hutton, late of the Royal 

 Academy, Woolwich. That work however being now out 

 of print, and the stock of questions considerably increased, 

 Mr. T. Leybourn, editor of the Mathematical Repository, 

 has issued proposals for publishing, by subscription, all the 

 mathematical questions and their answers, from the com- 

 mencement (/-f the Diary to the present time. Besides the 

 valuable notes given in Dr. Hutton's edition, the present 

 editor intends to give others, and in particular he means 

 to give, as far as he can, brief notices of any circumstances 

 he may be able to learn respecting such authors of the an- 

 swers to the questions as are dead, and even of such as are 

 alive when it can be done with propriety. 



But as many of the authors have now been dead for a 

 number of years, and have not been known beyond the 

 particular circle of their friends, he is aware that this part 

 of the work can only be rendered tolerably complete by the 

 assistance of such friends to his undertakmg as may be ca- 

 pable of giving the information here speciried. He ven- 

 tures, therefore, through the medium of The Philosophical 

 Magazine, to solicit communications respecting the authors 

 of the mathematical parts of the Diary. These may be ad- 

 dressed to him at the Koyal Military College, Great Mar- 

 low, Bucks.

The following Resolutions must be interesting to our 

 readers, being an extract from a very recent publication of 

 the Original Vaccine Pock Institution, in Broad-street, 

 Golden-square, containing the resultti of eleven years prac- 

 tice, which has the candour to publish the defects as well 

 as the advantages of vaccination. 



1. That it does appear in the practice of this Institution 

 that the small-pox has occurred subsequently to vaccination 

 in the most distinct manner, in the proportion of about one 

 of 550 in 5000 patients. 



2. That in these cases of failure the small-pox was in 

 rione very severe, but, on the contrary, in most of them 

 milder than usual in even the inoculated small-pox. 



3. That ther^ have not occurred any aliiiming vaccine 

 cases, excepting in a very small proportion from inflamed 

 and sore arms. 



4. That in many hundreds subjected to the countcrproof 

 of re-inoculation with variolous matter, not one has taken 

 the small-pox, 



5. That
