nocturnal folar gravitation, that it can fcarcely be afcribed to this 

 influence. At the fame time it is curious to obferve, that veget- 

 ables in refpect to their times of fleeping more regularly obferve 

 the huur of the day, than the prefence or abfence of light, or of 

 heat, as may be feen by confulting the calendar of Flora. Bo-

Some difeafes, which at firft light might be fuppofed to be in- 

 fluenced by folar periods, feem to be induced by the increafmg 

 ieniibility of the fyllem to pain during our fleeping hours ; as 

 explained in Seel:. XVIII. 15. Of thefe are the fits of afthma, 

 of lome epilepfies, and of fome Lxmoptoes ; all which dilturb 

 the patient alter lome hours fleep, and are therefore to be af- 

 cribed to the increafe of our dormant fenfibility. There may 

 Jikevvife be fome doubt, whether the commencement of the pain 

 of gout in the foot, as it generally makes its attack after fleep, 

 fhould be afcribed to the increafed fenfibility in fleep, or to fo- 



' influence ? 



M. M. When aflhmatic or epileptic fits or hiemoptoe occur 

 after a certain number of hours of fleep, the patient mould be 

 forcibly awakened before the expected time by an alarm clock, 

 and drink a cup of chocolate or lemonade. — Or a grain of opi- 

 um fhould be given at going to bed. — In one cafe to prevent 

 the too great increafe of fenfibility by fhortening the time of 

 fleep •, and in the other by increafmg the irritative motions, and 

 expending by that means a part of the fenforial power. 



2. Studii inanii periodus. Clafs 111. j. 2. 2. The cataleptic 

 fpafm which preceded the reverie and fomnambulation in the 

 patient, whofe cafe is related in Seel. XIX. 2. occurred at ex- 

 actly the fame hour, which was about eleven in the morning for 



ny weeks ; till thofe periods were dilturbed by large dofesof 

 opium ; and muft therefore be referred to fome effect of folar 

 gravitation. In the cafe of Mailer A. Sect. XXXIV. 3. as the 

 reverie began early in the morning during fleep, there may be a 

 doubt, whether this commenced with torpor of fome organ 

 catenated with folar gravitation ; or was caufed by the exig- 

 ence of a previous torpid part, which only became fo painful as 

 to excite the exertions of reverie by the perpetual increafe of 

 fenfibility during the continuance of fleep, as in fome fits of epi- 

 lepfy, ailhma, and hiemoptoe mentioned in the preceding article.

 2. 2. 8. The torpor and confequent pain of fome membranes 

 on one fide of the head, as over one eye, are frequently occa- 

 fioned by a decaying tooth, and are liable to return every day, 

 or on alternate days at folar or lunar periods. In this cafe large 

 quantities of the bark will frequently cure the difeafe, and es-
