Does anyone have a copy of the book Church Records of the 18th Century, 1768-1800 by F. Edward Wright?

I'm seeking the complete transcription of the following two baptisms / dates of birth if listed, but I'm not sure if it's in this book or another book. It's for sure in some book of baptisms in Maryland. :>)

Frederick/Washington Co., MD
book that lists baptisms, etc. the following:
PETER WIRT and ELISABETH, parents of two children
bapt. @ Salem German Reformed Church, Conscocheague Dist., Washington Co., MD:

Their two children baptized at the above named church are:
Valentine Wirt, baptised 19 Jan 1772
Eva Wirt, baptised 30 Mar 1777

If anyone knows if their baptisms are recorded in the above book or in another book, I would like to the the complete transcription with page numbers, name of church, parents, name of church, etc.

Thanks
Nancy
