collect any useful information from their writings. But it is 
certain the place of the moon has some influence on the 
weather. That changes of weather oftener take place about the 
full and new moon,and alout the quadratures, than at other 
times, ts really a fact founded on long observation.” 
I apprehend that the moon in conjunction with, or in opposi- 
tion to, the sun, are two data whence the old notions of the astro+ 
logers were formed; and if the quadratures may be considered 
productive of any variations in the atmosphere, the moon’s posi- 
tien with respect to the sun appears to be the only rational 
mode of accounting for them. 
If Mr. Forster should be induced to consider the operations of 
Saturn, Jupiter, &c. possible, he will most probably be con- 
vinced that the variations in the atmosphere are not dependent 
solely on the moon.

My Lorp,— Worn the last year the surgeons of our dif- 
ferent stations in London have vaccinated 6,581 persons, and 
have distributed to the public 32,821 charges of vaccine lymph. 
We cannot state precisely what the sixty-eight honorary and 
corresponding vaccinators may have effected in the country, as 
returns are not always sent: however, we have ascertained that 
those practitioners whom we have supplied with lymph have 
varcinated 42,667 in the course of the year. 
We have the satisfaction of informing your lordship, that we 
have furnished the means of disseminating this blessing in the 
island of St. Domingo; and that the director has received the 
annexed letter from the government of Hayti on that subject. 
It is equally gratifying to us to state, that by the ingenuity of 
Mr. Giraud of Faversham, means have been devised of preserving 
the lymph in a fluid state ; by which we have just reason to hope 
that it may be found efficient in any elimate, and for any space 
of time. 
Your lordship has probably been informed, that in consequence
