during the time of winter, the pores of the Earth being ftopt, and 

 the Mineral thereby not permitted to exhale, the water is then 

 impregnated with it, and gives the tinfture ; whereas in the fum- 

 mer feafon it expires fo much, that the depauperated water can 

 fliew nothing of it. That waters do thus alter according to the 

 Seafons of the Year, I found alfo to be manifeft from the waters 

 of Deddington, which I found fomtimes lighter* and at other 

 times heavyer than common water, and to give much difterentye- 

 diments at divers tryals with the lame materials. And this I 

 thought convenient to note, not only to excite Men to more cri- 

 tical Obfervations, but that the curious Explorator may not be 

 ftartled, in cafe he find them at any time not exa&ly to anfwer. 



63. In the Park at Cornbury, not far from the Lodge, in a 

 pit newly digged, there rifes a firing alfo of a Vitriol kind , co- 

 louring the mud and earth under it very black ; into this pit, it 

 being defigned for a conservatory of Eifh, they put over night 

 fome of feveral forts, but found them next day in the morning 

 all dead ; which gave me good ground tofufpefl: (having juft be- 

 fore met with a relation of Dr. Wit ties 1 , That Carps put into a 

 Copper Brewing-veffel to be preferved but for one night, were all found 

 dead in like maner in the morning) that here might be fomthing of 

 that nature too ; and that the Vitriol wherewith this water is fated, 

 might rather be that of Venus than Mars : And in thefe thoughts 

 I was the more confirmed, when I quickly after was informed, of 

 an odd kind of fteam that rofe hereabout of a fuitable effect* 

 But of this no more, leaving its further confideration to the 

 Right Honorable and ingenious Proprietor of the place, and my 

 Angular good Lord, Henry Earl of Clarendon, a moft effectual 

 cncourager of thisdefign. 



64. To thefe I muft add another fort of 'waters, which though 

 in taft they refemble milk? muft yet I believe be reduced to this 

 Head, for I find, notwithftanding their eminent fweetnefs, they 

 all refufe to lather with foap, and therefore conclude them to hold 

 fome Acid : Of thefe we have feveral within the City of Oxford, 

 one at a Pump over-againft the Crofilnn, another near the Mount 

 in New College Gar den, and a third at the Pump at Buckley Hall, 

 now the dwelling houfe of one Mr. Bowmam Book-feller, and 

 feveral other places * : All which, notwithftanding their lacleous
