In the above charts the dotted lines are " isobars," or lines of eqnal barometrical pressure, the valnes which they indicate being 

 given in figures at the end, thus — 30'4. The shade temperature is given in figures for several places on the coast, and the weather is 



recorded in words. The arrows fly with the wind, the force of which is shown by the number of barbs and feathers, thus : — »- 



light J >-, fresh or strong; > :> , a gale ; » ■ > , a violent gale ; signifies calm. The state of the sea is noted in capita} 



letters. The • denotes the various stations. The hour for which each chart is drawn is C p.m.

I have tested all these rings in practice, and have found the 

 theory true in all cases, the requisite conditions being, of course, 

 good eyesight and good light ; in very hazy, bad lights, nothing 

 but the most open sights will allow the bull even to be seen ; but in 

 strong lights, with a heavy mirage, I have found the rings equally 

 serviceable, the diffraction fringe hiding the image as effectually as 

 it docs the bull's-eye when it gets behind it. F. T. P. 



The Stamping out of Smallpox. — An important experiment, 

 which is exciting the greatest interest in medical circles, is being 

 made at Leicester, under the care of Dr. William Johnston, medical 

 officer of liealth. There are more cases of noncompliance with 

 the compulsory vaccination laws in Leicester than in all the other 

 towns of the kingdom pnt together. Hence the past six months 

 have witnessed very serious outbreaks of smallpox of a very 

 virulent kind in the midlands, and at Liicestcr a verj- considerable 

 number of cases have been imported from London, Birmingham, 



Nottingham, and other towns. Every one of these outbreaks was 

 stamped out by the following method : — Tlio corporation have 

 powers under a local Act of Parliament compelling, under a heavy 

 penalty, medical men and householders promptly to report 

 the outbreak of infectious diseases, including smallpox and 

 fever, the medical men receiving a small fee for each report. 

 In the event of a case of smallpox being reported at the 

 sanitary offices, which are directly connected with the fever and 

 cmall-pox hospitals by means of the telephone, an officer at onco 

 communicates with the institution, tho removal van is placed in 

 readiness, and beds are prepared for the reqnisito number of 

 patients. The medical officer of health and an inspector at onco 

 visit tho house where the outbreak lias occurred, explaining tho 

 nature of tho disease to the inmates, and invariably succeed in 

 inducing not only the patients to bo removed to tho hospital, but — 

 what is of equal importance — in inducing every one who has come 

 into contact with tho sufferer, and every one living in the same 

 house, to occupy quarantine rooms at tho hospital. The telephone 

 is again brought into requisition, and the roninvals take place with 

 the least possible delay. Those in quarantine are provided with 

 every comfort and means of recreation until the period of quaran- 

 tine has elapsed, and meantime, the house where tho outbreak 

 occurred is thoroughly disinfected, at tho expcnso of the local 

 authorities. — Times.
