Opening bowler Mohammad Abbas took 4-23 and Hasan Ali, a star of Pakistan's Champions Trophy triumph in the United Kingdom past year, picked up 4-51.
"Good two days, we will enjoy them", Pakistan coach Mickey Arthur said, "but the reality is we've got plenty to do".
Cook equalled former Australian captain Allan Border's world record of 153 Test appearances in succession.
Pakistan, whose players do not feature in the Indian Premier League, had arguably had better preparation for this series than that enjoyed by England's Ben Stokes and Jos Buttler while they were playing in the lucrative Twenyty20 event. "Fifty for one can very quickly become 80 for four".
Asad Shafiq (59) and Babar Azam, who made 68 before retiring hurt, kept the runs coming before Shadab Khan (52) hit his second half-century in three Tests.
Canada restaurant blast: India offers help to trace suspects
The first male suspect is said to be in his 20s, and between five-foot-ten and six feet tall with light skin and a stocky build. Bertram said there were several family gatherings in the restaurant at the time, involving people of "a wide range of ages".
Unlike the first two days, the sun was out on day three at Lord's as the England openers made their way on to the pitch with nearly the entire day's play to look forward to. "The pitch is dry, the forecast is it's going to get warmer, but there is live grass on it".
Mark Stoneman's dismissal for four continued his unprofitable alliance with Alastair Cook at the top of the order.
Mark Stoneman's unconvincing global career continued when he was bowled by Abbas for four, beaten as he tried to drive a full-length delivery which clipped the top of his off stump.
The pair grafted away and picked off the loose balls before fast bowler Mark Wood eventually ended a stand worth 75 runs when, having tried to "rough up" the batsmen from around the wicket, he slipped in a fuller-length delivery that Haris (39) edged to wicket-keeper Jonny Bairstow.
But the work of team fielding coach Steve Rixon, the former Australia wicket-keeper, was rewarded when Asad Shafiq held a hard catch at second slip edge after Jos Buttler, recalled as a specialist number seven, edged a drive off Hasan and fell for 14.
After the end of the first day's play of the Test match, the International Cricket Council's (ICC) Anti-Corruption and Security Unit banned the use of smartwatches during any cricket match as two of the Pakistan cricketers Hasan Ali and Babar Azam were seen wearing the device on the field during play.
