542 reports of american observatories. 



173 Gates Avenue, Brooklyn. 



I have been trying in vain nearly a year to obtain the Harvard Vol. IX, 



to aid me in photometric work. Hope to get it soon. For that reason, 



and from other business, my observatory has remained idle this year 



and does not deserve a place in your notices. I hope to resume work 



next year ; but my eyes need rest, and do not seem to improve in this 



long astronomical recess. 



Yours, truly, 



Henry M. Parkhurst.
