202 SUMMARY OF CURRENT RESEARCHES RELATING TO 
MICROSCOPY. 
‘ [The Publication Committee of the Journal has decided on resuming the issue 
of the Microscopic Bibliography, which was dropped on the lamented death of 
Mr John Mavall, iun. It is intended in future to give at least the title ot 
every work or paper (commencing from January 1st, 1899) coming under the 
head of Microscopy A or of Technique 3 (Microtomes); and we shall be much 
obliged to any of our Fellows who will call our attention to any such papers or 
articles published in Journals which are likely to escape our notice.— Editor.]
