naturally covered with fossile salt; again, that those lakes are furnished with 

 vast animals, as crocodiles, hippopotami, and doubtless great VHriety of other 

 smaller animals ; from all these things, well considered, it is easy to imaginCj 

 that in a year's time most of the salt water of those lakes has passed through 

 the bodies of those animals, and consequently is become urinous or saline uri- 

 nous, as is the nature and composition of factitious sal ammoniac. 



Observations on the Practice of Physic. By Dr. Turbervilley of Salisbury. 



N° 167, p. 839. 



A gentlewoman was much troubled with the falling sickness; in her water I 

 saw a great number of short worms, full of legs, and like millepedes; I gave 

 her 2 or 3 purges, first with pil. agaric, and rhubarb; but still perceived in 

 every water that was brought me, 8, 10, or more, of the worms. They ap- 

 peared lively and full of motion; and the fits continued daily. At last I gave 

 her 4- an ounce of oxymel helleboratum, in tansy water, which wrought well, 

 and was successful ; so that she had a complete cure. 



About 6 or 7 years since, I had a gentleman (Mr. OylifF) in cure for his eye, 

 which was as large as my fist, black, fleshy, and full of bluish bladders; this I 

 judged to be a cancer. After purging and bleeding, I cut out the ball and 

 ulcered flesh, by many cuts, which were all insensible to him, till I came to the 

 optic nerve ; at the last cut he complained, and bled a little, the wound was 

 healed in about a fortnight; he now wears a black patch over the place. 



Not long after this, a young man had an eye as large as a hen's egg, very 

 fair, without blemish, rheum, or redness^ and his sight was pretty tolerable. I 

 judged these symptoms to proceed from thin humours fallen on the eye, and 

 distending its coats. I cured this distemper by applying drying medicines to 

 the head and eyes, and making an issue in nucha. Appello morbum oculura bo- 

 vinum, sive oculi hydropem. 



Obsei-vations on the Cicindela Folans, or Flying Glow-worm. By Ricliard Waller, 



Esq. F.R.S. N° 167, p. 841. 



The cicindela volans* is but rarely found in England, though I have happened 

 twice to catch them at Northaw in Hertfordshire; they flew about the candle 

 as soon as it grew dark; at both which times the weather was very hot, and per- 

 haps it shines only at such seasons, though the animal be easy enough to be 

 met with, all winged when it shines not, and without wings shining, which is 



* The insect here described is not the common glow-worm, the female of which is wingless. It 

 geems very nearly allied to the Italian glow-worm, lampyris Italica of Linnaeus.
