New Injection Syringe for Bacteriological Purposes.* — Dr. F. 

 Inghilleri has invented a syringe (fig. 59) which consists of a glass tube 

 divided by constrictions into thi"ee portions ABC. B is the receiver 

 for the fluid to be injected. It may be made of different capacities, is 

 marked with a scale, and ends in a nozzle on which the trocar fits. The 

 expansion G is intended to provide against the fluid being accidentally 

 drawn into the air chamber A, the lower part of which is stuffed with 

 cotton-wool. The piston D works in A. The piston-rod is a hollow

tube and its upper end carries a cap over which the thumb is pressed 

 during injection. When the apparatus is to be sterilised the piston 

 is removed and the trocar inserted in A. after the lower end has been 

 plugged with cotton-wool. The object of the hollow piston-rod is to 

 allow the plunger to be pushed down if the receiver B does not fill suffi- 

 ciently. 



Stand for Holding Slides.f — K. Holzapfel describes a frame or stand 

 for holding a considerable number of slides. The apparatus is intended 

 for the treatment of paraffin serial sections. It is made of glass and is so 

 constructed that it fits inside a glass jar. The construction and the way 

 it is intended to be used are easily gathered from an inspection of the 

 accompanying illustrations (figs. 60 and 61).
