IN MEMORIAM. 235 



has given many others at intervals since that time. He 

 designed the lamp shade which, in a modified form, is still in 

 use upon microscope lamps, and, in 1877, designed and brought 

 before the Club a very useful machine for cutting both hard 

 and soft sections. Although interested in every branch of 

 microscopy, and possessing more or less knowledge upon every 

 branch, he had devoted himself for many years almost entirely 

 to the study of the Foraminifera, and of beautifully mounted 

 slides of these, as well as of foraminiferous material, he 

 possessed a large and valuable collection. 



Until attacked with the disease which caused his death he 

 does not seem ever to have had any very serious illness, at any 

 rate after his marriage. He had, however, for years suffered 

 intensely, and at somewhat frequent intervals, from hemicrania, 

 and was often quite prostrated by the violence of these attacks 

 of headache. On Saturday, the 15th October last, he returned 

 home from the City apparently in his usual health. A window 

 had been broken at the back of the house in which he lived, 

 and Hailes, who liked, as far as possible, to do all the work 

 about his home for which most people employ the British 

 artisan, set to work to repair the damage. A cold north-east 

 wind was blowing, and the job occupied rather longer than 

 usual because of his breaking one pane of glass and having to 

 get another. It was, doubtless, while doing this that he caught 

 the chill which caused his death. On Sunday he did not go 

 out all day, feeling less well than usual, and being troubled 

 with toothache ; but on Monday he felt better and got up to go 

 to business as usual. Before starting, however, he had a 

 violent fit of shivering and returned to bed. On Tuesday he 

 again got up ; but the doctor, who was then called in, sent him 

 again to bed. An examination showed that he was suffering 

 from a sharp attack of pleurisy and pneumonia, and that his 

 heart was also weak ; at that time, however, the doctor hoped 

 to be able to save his life. On Wednesday he was much worse, 

 and on Thursday afternoon he evidently felt that his end was 

 near. He then took leave of all his family, being quite con- 

 scious, and speaking to each one individually. In the evening 

 he rallied a little, though breathing was extremely difficult, 

 and the heart was not only weak, but had become displaced by 

 his starting up in bed. During the night, however, he became 

 weaker until, just before eight on Friday morning, he passed
