 is first thoroughly s.-uked, is wrung ai.d placed iu the mrichine 

 (taking care not to close up any of the holes in the tube), and left 

 for half an hour on the fire. 'The machine is then removed from 

 the fire, and the contents poured into a tub and well rinsed. If 

 necessary, the machine is again prepared as at first, and again 

 heated for half an hour, and the linen will, it is claimed, be per- 

 fectly soft and white, without having received any injury in the 

 washing. The circulation of the water produced in this apparatus 

 is its feature. 



LIFEBOAT. 

 [Patent Xo. 4,411. 1885.] This boat, invented by Sir. James 

 Wright, of 97, Lucey-street, Bermondsey, S.E., is designed and 

 constructed to right itself with sails set and sheets fast, dis- 

 charging the whole of the water shipped in TS or 24 seconds. 

 Her lines are straighter and shear much lower than that of other 

 self-righting boats, making greater speed with head to wind. 

 She has been thoroughly tested at Brighton, Ramsgate, and 

 Margate : and also, previously, in the West India Docks and 

 the Thames, manned with miniature weighted model men, and 

 afforded great satisfaction to those present. The chief novelty 

 of the invention, patented, is the peculiar construction of the 

 fore-and-aft air-tight compartments, without which no boat with 

 " sails set and sheets fast" can right itself. 



SASH- FASTENER. 

 [Patent No. 535. 1885.] — This is a simple, but ingenious, inven- 

 tion by Colonel Henry, of 35, Stanhope-gjrdens, S.W. The object

fix it, take the sash-frames out in the usual way by removing 

 beading ; rip the old sash-line off, taking out all" nails. Fit the 

 fastener to the existing slot iu frame ; the fastener must fit the 

 groove or slot easily, care being taken to keep the fastener in 

 centre of sash bar. Countersink top of sash bar to allow flat top 

 of fastener to go in flush. When accurately fitted put a screw into 

 the slot of frame through the fork of fastener, about midway, and 

 turn the screw down until the head nearly touches the fork. Now 

 take the fastener out and place one end of the new sash-line in 

 lower end of fastener, as shown in Fig. 2, by means of the three 

 screws, which will now hold the rope or line quite firmly, and the 

 fastener can be screwed down to the frame. The "sash-frame 

 should now be put back in its proper position, the other end of the 

 rope passed over the pulley, and fastened to weight in the usual

A Fatal Error. — Tjwo male patients have, says the Lancet, been 

 poisoned in St. Lonis nospital, Paris. The pupil in the dispensing 

 department sent poison up to the wards instead of the mixture 

 which was ordered. The dispenser, on becoming acquainted with 

 the deplorable result of his carelessness, attempted to commit 

 suicide, and was only restrained from affecting his purpose by the 

 exercise of considerable violence on the part of the other students. 



From the Report and Pass-List of the Technological Examina- 

 tions held by the City and Guilds of London Institute in May last, 

 we gather that no less than 3,968 candidates presented themselves, 

 of whom, however, 2,168 only, or some 55 per cent., succeeded in 

 passing. Some of the examiners speak of a satisfactory improve- 

 ment in the character of the papers submitted, but there is much 

 more "damning with faint praise" (to say nothing of actual fault- 

 finding) than seems quite desirable.
