spiral deposit does not consist of one long-, continuous fibre, 

 as usually stated in books, but in reality it is made up of 

 comparatively short pieces, rarely extending - unbroken be- 

 yond a few turns round the tube. Mr. Michael doubted if 

 this observation was new, and thought the correct struc- 

 ture, which was as stated by Mr. Merlin, would be found 

 described in the more modern German works — suchas,for 

 instance, Lang's "Comparative Anatomy." Mr. Hughes 

 also quoted some authorities to the same effect. Mr. Hil- 

 ton thought the very term "spiral fibre" a misnomer. In 

 some cases, at least, it could be made to disappear on pres- 

 sure, and in his view the appearance was produced by fold- 

 ing - , like the extending - bellows of a camera, and was oblit- 

 erated in the same way by being - stretched. Mr. J. T. 

 Holder then gave an exhibition with the lantern, project- 

 ing - some 130 beautiful photographs on the screen. The 

 subjects comprised vegetable and animal histology, dia- 

 toms, radiolaria, and foraminifera, &c, and were all his 

 own work. A very cordial vote of thanks to Mr. Holder 

 was moved by the President and carried by acclamation. 

 The deaths of Mr. J. W. Bailey, Mr. W. Goodwin, and 

 Amos Topping - , the well-known mounter, were referred to.

The fact that a second edition of Muirand Kitchie'sMan- 

 ual of Bacteriology has appeared in two years speaks well 

 for the work. It is essentially a work for practitioners and 

 students as it deals only with those bacteria and other low 

 organisms, Amoeba and Plasmodia connected with the dis- 

 eases of man. The work only deals with the pathogenic 

 bacteria of man and only incidentally touches upon those 

 occuring in lower animals when the same organism occurs 

 in both. It is to be regretted that the authors did not in- 

 clude the other animal bacterial parasites. It would have 

 added greatly to this excellent volume. The general ac-
